    ROHM Added a Lineup of Compact 600V Super Junction MOSFETs

    3 Min Read

    ROHM has added a lineup of compact 600V Super Junction MOSFETs R6004END4 / R6003KND4 / R6006KND4 / R6002JND4 / R6003JND4. These devices are ideal for small lighting power supplies, pumps, and motors.

    In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated – spurring the demand for compact MOSFETs that are essential for switching operation.

    Generally, however, it has been difficult to reduce the size of Super Junction MOSFETs while maintaining an optimal balance between high breakdown voltage and low ON resistance. In response, after reviewing the shape of the mounted chip, ROHM was able to develop 5 models in the SOT-223-3 package (6.50mm × 7.00mm × 1.66mm) – providing a smaller, lower profile form factor without compromising the performance of conventional products.

    Compared to the conventional TO-252 package (6.60mm × 10.00mm × 2.30mm), ROHM’s new products reduce area and thickness by 31% and 27% – contributing to smaller, lower profile applications. At the same time, the same land pattern (footprint) as the TO-252 package can be used, enabling mounting on existing circuit boards without modification.

    Offering distinctive features, three of the models optimized for compact power supplies. The R6004END4, characterized by low noise, is suitable for applications where noise is a concern, while the R6003KND4 and R6006KND4, capable of high-speed switching, are ideal for sets requiring low loss, high efficiency operation.

    The R6002JND4 and R6003JND4 utilize proprietary PrestoMOS technology to achieve significantly lower switching losses by speeding up reverse recovery time (trr), making them well-suited for motors-equipped devices.

    Supporting materials such as application notes, technical documents, and SPICE simulation models for each product are available on ROHM’s website free of charge to enable quick market introduction.

    Going forward, ROHM will continue to expand its Super Junction MOSFET lineup in different packages and even lower ON resistances that contribute to solving social issues such as environmental protection by reducing power consumption in variety devices.

  • Alpha and Omega Semiconductor Added a 100V MOSFET in DFN 5x6 Package

    Alpha and Omega Semiconductor Added a 100V MOSFET in DFN 5×6 Package

    2 Min Read

    Alpha and Omega Semiconductor Limited (AOS) announced the AONA66916, a 100V MOSFET packaged in the company’s innovatively designed top and bottom side cooling DFN 5 x 6 package. Designers have long trusted AOS power semiconductors as essential components that help them meet a wide variety of high performance application requirements.

    Now, in delivering a state-of-the-art package that keeps its semiconductor products cooler, AOS is taking a huge step in enabling engineers to develop more efficient designs in telecommunications and industrial applications that must frequently operate in harsh conditions.

    Typically, when using the standard DFN 5×6 package, the bottom contact is the main contributor for cooling, and most of the heat generated by the Power MOSFETs will be transferred to the PCB. This increases the PCB thermal management design considerations to meet system requirements. AOS’ new top and bottom cooling DFN 5×6 package is designed to achieve the highest heat transfer between the exposed top contact and heat sink due to its large surface contact area construction.

    This allows the device to achieve a low thermal resistance (Rthc-top max) of 0.5°C / W with results being transferred to the PCB board, enabling significant thermal performance improvements. The top exposed DFN 5×6 package of the AONA66916 shares the same 5mm x 6mm footprint as AOS’ standard DFN 5×6 package, eliminating the need to modify existing PCB layouts.

    Another benefit of the AONA66916 is that it utilizes AOS’ 100V AlphaSGT™ technology, providing excellent FOM for balanced performance in hard switching applications. AONA66916 has a maximum RDS(on) rating of 3.4mOhms and has a 175°C junction temperature rating.

    “Cooling the power MOSFET in high power design can be challenging, and AOS has successfully addressed this essential issue with our advanced top exposed package design. It not only enables better thermal transfer from its top side exposed contact to heat sink due to large exposed surface area, our new package delivers a much cooler device that contributes to a more efficient and robust final design,” said Peter H. Wilson, Marketing Sr. Director of the MOSFET product line at AOS.

    Qorvo Unveiled Automotive-Qualified SiC FET in a Compact D2PAK-7L Package

    2 Min Read

    Qorvo® unveiled an automotive-qualified silicon carbide (SiC) field effect transistor (FET) offering an industry-best 9mΩ RDS(on) in a compact D2PAK-7L package. This 750V SiC FET is the first in a new family of pin-compatible SiC FETs from Qorvo with RDS(on) options up to 60mΩ, making them well suited for electric vehicle (EV) applications, including on-board chargers, DC/DC converters and positive temperature coefficient (PTC) heater modules.

    The UJ4SC075009B7S features a 9mΩ typical RDS(on) at 25°C needed for reducing conduction losses and maximizing efficiency in high voltage, multi-kilowatt automotive applications. Its small, surface-mount package enables automated assembly flows and reduces customer manufacturing costs. This new 750V family complements Qorvo’s existing 1200V and 1700V automotive SiC FETs in D2PAK packaging to form a complete portfolio addressing EV applications that span 400V and 800V battery architectures.

    Ramanan Natarajan, director of Product Line Marketing for Qorvo’s Power Products, said, “The launch of this new family of SiC FETs demonstrates our commitment to providing EV powertrain designers the most advanced and efficient solutions for their unique automotive power challenges.”

    These fourth generation SiC FETs leverage Qorvo’s unique cascode circuit configuration, in which a SiC JFET is co-packaged with a Si MOSFET to produce a device with the efficiency advantages of wide bandgap switch technology and the simpler gate drive of silicon MOSFETs. Efficiency in SiC FETs is dependent on conduction losses, and Qorvo’s cascode/JFET approach enables reduced conduction losses through industry-best RDS(on) and body diode reverse voltage drop.

    The key features of the UJ4SC075009B7S include:

    • Threshold voltage VG(th): 4.5V (typical) allowing 0 to 15V drive
    • Low body diode VFSD: 1.1V
    • Maximum operating temperature: 175°C
    • Excellent reverse recovery: Qrr = 338 nC
