ROHM’s New SiC Schottky Barrier Diodes for High Voltage xEV Systems: Featuring a Unique Package Design for Improved Insulation Resistance

　　ROHM has developed surface mount SiC Schottky barrier diodes (SBDs) that improve insulation resistance by increasing the creepage distance between terminals. The initial lineup includes eight models - SCS2xxxNHR - for automotive applications such as onboard chargers (OBCs), with plans to deploy eight models - SCS2xxxN - for industrial equipment such as FA devices and PV inverters in December 2024.　　The rapidly expanding xEV market is driving the demand for power semiconductors, among them SiC SBDs, that provide low heat generation along with high-speed switching and high-voltage capabilities in applications such as onboard chargers. Additionally, manufacturers increasingly rely on compact surface mount devices (SMDs) compatible with automated assembly equipment to boost manufacturing efficiency. Compact SMDs tend to typically feature smaller creepage distances, fact that makes high-voltage tracking prevention a critical design challenge.　　As leading SiC supplier, ROHM has been working to develop high-performance SiC SBDs that offer breakdown voltages suitable for high-voltage applications with ease of mounting. Adopting an optimized package shape, it achieves a minimum creepage distance of 5.1mm, improving insulation performance when contrasted with standard products.　　The new products utilize an original design that removes the center pin previously located at the bottom of the package, extending the creepage distance to a minimum of 5.1mm, approx. 1.3 times greater than standard products. This minimizes the possibility of tracking (creepage discharge) between terminals, eliminating the need for insulation treatment through resin potting when surface mounting the device on circuit boards in high voltage applications. Additionally, the devices can be mounted on the same land pattern as standard and conventional TO-263 package products, allowing an easy replacement on existing circuit boards.　　Two voltage ratings are offered, 650V and 1200V, supporting 400V systems commonly used in xEVs as well as higher voltage systems expected to gain wider adoption in the future. The automotive-grade SCS2xxxNHR are AEC-Q101 qualified, ensuring they meet the high reliability standards this application sector demands.　　Going forward, ROHM will continue to develop high-voltage SBDs using SiC, contributing to low energy consumption and high efficiency requirements in automotive and industrial equipment by providing optimal power devices that meet market needs.　　Application Examples◇ Automotive applications: Onboard chargers (OBCs), DC-DC converters, etc.　　◇ Industrial Equipment: AC servo motors for industrial robots, PV inverters, power conditioners, uninterruptible power supplies (UPS), and more　　Online Sales InformationAvailability: The SCS2xxxxNHR for automotive applications are available now.　　The SCS2xxxN for industrial equipment are scheduled in December 2024.　　Pricing: $10.50/unit (samples, excluding tax)　　Online Distributors: DigiKey™, Mouser™ and Farnell™　　The products will be offered at other online distributors as they become available.　　EcoSiC™ BrandEcoSiC™ is a brand of devices that leverage silicon carbide, which is attracting attention in the power device field for performance that surpasses silicon. ROHM independently develops technologies essential for the advancement of SiC, from wafer fabrication and production processes to packaging, and quality control methods. At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.　　TerminologyCreepage Distance　　The shortest distance between two conductive elements (terminals) along the surface of the device package. In semiconductor design, insulation measures with such creepage and clearance distances must be taken to prevent electric shocks, leakage currents, and short-circuits in semiconductor products.　　Tracking (Creepage Discharge)　　A phenomenon where discharge occurs along the surface of the package (insulator) when high voltage is applied to the conductive terminals. This can create an unintended conductive path between patterns, potentially leading to dielectric breakdown of the device. Package miniaturization increases the risk of tracking by reducing creepage distance.　　Resin Potting　　The process of encapsulating the device body and the electrode connections between the device and circuit with resin, such as epoxy, to provide electrical insulation. This provides durability and weather resistance by protecting against water, dust, and other environmental conditions.　　AEC-Q101 Automotive Reliability Standard　　AEC stands for Automotive Electronics Council, a reliability standard for automotive electronic components established by major automotive manufacturers and US electronic component makers. Q101 is a standard that specifically applies to discrete semiconductor products (i.e. transistors, diodes).

ROHM’s New PWM Controller ICs with SOP Package for Power Supply in a Wide Variety of Industrial Applications

　　ROHM has developed external FET-type controller ICs utilizing PWM current control mode optimized for AC-DC power supply in various industrial applications. Mass production has begun for four variants designed to drive a wide range of power semiconductors: the BD28C55FJ-LB for low-voltage MOSFETs, BD28C54FJ-LB for medium- to high-voltage MOSFETs, BD28C57LFJ-LB for IGBTs, and BD28C57HFJ-LB for SiC MOSFETs.　　Although the global semiconductor shortage is beginning to ease, the supply of semiconductor components for power supplies in industrial applications continues to lag behind demand. This is particularly true for PWM controller ICs, where the limited number of manufacturers has resulted in chronic shortages, leading to numerous requests for product development.　　In response, ROHM has developed PWM controller ICs that address the ongoing supply issue by meeting the industrial market’s stringent package and performance requirements. Depending upon the input AC voltage range of the application, a wide variety of semiconductors are used for power supply circuit. Each of these semiconductors demand different undervoltage lock out levels to prevent thermal runaway in case of supply/gate voltage drop. To solve this issue, ROHM has developed 4 variants with different undervoltage lock out levels.　　The new products feature an input voltage range of 6.9V to 28.0V, circuit current up to 2.0mA, maximum startup current of 75µA, and a maximum duty cycle of 50%, offered in the standard SOP-J8 package (equivalent to the JEDEC SOIC8). The products are pin to pin compatible to standard products commonly used in power supply circuits, thus reducing re-design and modification efforts. All variants are equipped with a self-recovery-type undervoltage lockout function (UVLO) with voltage hysteresis. This significantly improves application reliability by reducing the threshold voltage error to ±5%, compared to the typical ±10% of standard products.　　At the same time, these ICs are designated for long-term supply, thus ensuring continuous operation of long-life industrial equipment. Going forward, the lineup will be further expanded to include products suitable to drive high-voltage MOSFETs and GaN devices. More variants to support a maximum duty cycle of 100% are also being planned.　　Application ExamplesIndustrial equipment: AC-DC power supplies, motor drive inverters, and other AC-powered devices　　Product Information　　Applicable Part Nos: BD28C54FJ-LB, BD28C55FJ-LB, BD28C57HFJ-LB, BD28C57LFJ-LB　　TerminologyPWM Control Type　　Short for Pulse Width Modulation, a method for controlling power using semiconductors. The output power is controlled by varying the ratio of ON and OFF times within a fixed cycle.　　Duty Cycle　　The proportion of ON and OFF times as percentage of the switching period is known as ON- and OFF-duty cycle, respectively. It is common to refer to the ON-time ratio as the duty cycle. Duty Cycle (%) = Pulse Width (t) / Period (T).　　Self-Recovery Undervoltage Lockout Function (UVLO) with Voltage Hysteresis　　This function safety stops IC operation before the circuit inside the IC becomes abnormal when the input voltage drops below a threshold. For self-recovery types, the IC can become unstable by repeatedly stopping and starting near the threshold voltage, so a protection circuit with hysteresis is used to create a voltage difference between the stop and restart points.

In 2014, Murata successfully brought to market the world’s first 008004-inch size (0.25×0.125mm) multilayer ceramic capacitors, which have experienced growing utilization in smartphone modules and wearable devices. The creation of this MLCC is the outcome of years of focused R&D in elemental technologies, resulting in a device that measures just 0.16mm x 0.08mm x 0.08mm (L/W/T).　　“Under our slogan 'Innovator in Electronics' we will continue to lead the electronics industry by providing innovative products and developing technologies,” said Hidetoshi Nakagawa, General Manager of Ceramic Capacitor Marketing at Murata Manufacturing Co Ltd. He continued, “This product is another world’s first in a long line of Murata’s market defining MLCCs and will significantly contribute to the future miniaturization and improvement of our customer’s electronic devices.”　　This revolutionary product will be showcased at Murata’s booth (6H104) during the CEATEC JAPAN 2024 event, scheduled to take place at Makuhari Messe in Chiba Prefecture on October 15, 2024.
