N-Channel MOSFET further enhances its wide bandgap product family, addressing the growing demand for SiC solutions that enable higher efficiencies in automotive subsystems of electric and hybrid electric vehicles (EV/HEV) and higher power density (such as battery chargers, on-board chargers (OBC), high-efficiency DC-DC converters, motor drives, and traction inverters).
The DMWSH120H90SM4Q operates safely and reliably up to 1200V DS with a gate-source voltage (V gs ) of +15/-4V and an R DS(ON) of 75mΩ (typical) at 15V gs. The devices are designed for OBCs, automotive motor drives, DC-DC converters in EV/HEV and battery charging systems.
The DMWSH120H28SM4Q operates up to 1200V DS, +15/-4V gs and has a low R DS(ON) of 20 mΩ (typ) at 15V gs. This MOSFET is designed for motor drives, EV traction inverters and DC-DC converters among other EV/HEV subsystems. The low R DS(ON) allows these MOSFETs to operate at lower temperatures in applications requiring high power density.
Both products feature low thermal conductivity (R θJC =0.6°C/W) and drain current up to 40A for the DMWSH120H90SM4Q and 100A for the DMWSH120H28SM4Q. They also feature fast intrinsics and a robust body diode with a reverse recovery charge (Q rr ) of 108.52nC in the DMWSH120H90SM4Q and 317.93nC in the DMWSH120H28SM4Q. This enables them to perform fast switching and reduce power loss.
By using a planar fabrication process, Diodes has created new MOSFETs that offer more robust and reliable performance in automotive applications with increased drain current, breakdown voltage, junction temperature and power loop compared to previously released versions . The device is available in a TO247-4 (WH type) package with an additional Kelvin sense pin. It can be connected to a power supply to optimize switching performance for higher power density.
Both the DMWSH120H90SM4Q and DMWSH120H28SM4Q are AEC-Q101 compliant, manufactured in an IATF 16949 certified facility and support PPAP documentation. The DMWSH120H90SM4Q is available for $18 per thousand pieces and the DMWSH120H28SM4Q is available for $38 per thousand pieces.
