AEC-Q101 qualified 1200 V, 100A and 40A SiC MOSFETs from Diodes
Date: 02/07/2023
Diodes released automotive-compliant AEC-Q101 qualified Silicon Carbide (SiC) N-channel MOSFETs DMWSH120H90SM4Q and DMWSH120H28SM4Q automotive-compliant Silicon Carbide (SiC) MOSFETs for designing power electronics sys such as on-board chargers, automotive motor drivers, DC-DC converters in EV/HEV, and battery charging systems.
DMWSH120H90SM4Q operates up to 1200VDS with a gate-source voltage (Vgs) of +15/-4V and has an RDS(ON) of 75m? (milli ohms) (typical) at 15Vgs. This device is designed for on-board chargers, automotive motor drivers, DC-DC converters in EV/HEV, and battery charging systems.
The DMWSH120H28SM4Q operates up to 1200VDS, +15/-4Vgs, and has a lower RDS(ON) of 20 m? (milli ohms) (typical) at 15Vgs. This MOSFET has been designed for motor drivers, EV traction inverters, and DC-DC converters in other EV/HEV subsystems. Low RDS(ON) enables these MOSFETs to run cooler in applications that require high power density.
Both products have low thermal conductivity (R?JC=0.6°C/W), enabling drain currents up to 40A in the DMWSH120H90SM4Q and 100A in the DMWSH120H28SM4Q. They also have fast intrinsic and robust body diodes with low reverse recovery charge (Qrr) of 108.52nC in the DMWSH120H90SM4Q and 317.93nC in the DMWSH120H28SM4Q. This enables them to perform fast switching with reduced power losses.
Diodes said by using the planar manufacturing process, it has created new MOSFETs that offer more robust and reliable performance in automotive applications—and with increased drain current, breakdown voltage, junction temperature, and power rings as compared to previously released versions. The devices are available in a TO247-4 (Type WH) package, which offers an additional Kelvin sense pin. This can be connected to the source to optimize switching performance, enabling even higher power densities.
The DMWSH120H90SM4Q and DMWSH120H28SM4Q are manufactured in IATF 16949 certified facilities, and support PPAP documentation. The DMWSH120H90SM4Q is available at $18 in 1,000 piece quantities, and the DMWSH120H28SM4Q is available at $38 in 1,000 piece quantities.
