UnitedSiC adds 7 SiC FETs to 650V product range

     Silicon Carbide (SiC) power semiconductor manufacturer UnitedSiC/ United Silicon Carbide Co., Ltd. announced that it has added seven new TO220-3L and D2PAK-3L device/package combinations to the UJ3C (universal) and UF3C (Hard Switch) series 650V SiC FETs.

     These new devices provide a new level of high-voltage power performance for applications such as the rapidly growing data center server power supply, 5G base station telecommunication rectifiers, and on-board chargers for electric vehicles. These new devices will be extremely attractive to design engineers, who still prefer 3-pin, TO220 or D2PAK package options, but are also working to improve power performance in power factor correction circuits, LLC resonant converters, and phase-shifted full-bridge converters.

     UnitedSiC's UJ3C and UF3C FETs are unique in their true "direct replacement" capabilities. By replacing existing Si IGBTs, Si FETs, SiC MOSFETs or silicon super junction devices with UnitedSiC FETs, designers can significantly improve system performance without changing the gate drive voltage.

     Both series of SiC FETs are based on UnitedSiC's unique "common source, common gate" circuit configuration, where normally ON SiC JFET and Si MOSFETs are packaged together to build normally off SiC FETs with standard gate drive characteristics. As a result, existing systems upgraded with UnitedSiC "direct replacement" FETs will have a significant performance boost, enabling lower on-off and switching losses, enhanced thermal performance and integrated gate ESD protection. With a new design, UnitedSiC FETs offer higher switching frequencies, resulting in significant system benefits, enabling greater efficiency and reducing the size and cost of passive components such as magnetic components and capacitors.

     With UnitedSiC's sintered-silver package technology, the industry standard three-pin TO220-3L package offers enhanced thermal characteristics. New products available in this package include UJ3C devices with RDS (on) values of 30 and 80 Mω, and UF3C devices with RDS (on) specifications of 40 Mω.

     The three-lead industry standard D2PAK-3L package is designed for surface mount and is certified to IPC and JEDEC Moisture Sensitivity Level 1. New products available in this package include UJ3C devices with RDS (on) specifications of 30mΩ and 80mΩ, and UF3C devices with RDS (on) specifications of 30mΩ and 40mΩ. UnitedSiC also offers automotive grade devices that comply with the AEC-Q101 standard.
