Automotive-Compliant Silicon Carbide MOSFETs from Diodes Incorporated Enhance Automotive Subsystems Efficiency

Business Wire
Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announced a
further enhancement of its wide-bandgap product offering with the
release of the DMWSH120H90SM4Q and DMWSH120H28SM4Q
automotive-compliant Silicon Carbide (SiC) MOSFETs. These N-channel
MOSFETs respond to the increasing market demand for SiC solutions
that enable better efficiency and higher power density in electric
and hybrid-electric vehicle (EV/HEV) automotive subsystems like
battery chargers, on-board chargers (OBC), high-efficiency DC-DC
converters, motor drivers, and traction inverters.
The DMWSH120H90SM4Q operates safely and reliably up to 1200VDS
with a gate-source voltage (Vgs) of +15/-4V and has an RDS(ON) of
75mΩ (typical) at 15Vgs. This device is designed for OBCs,
automotive motor drivers, DC-DC converters in EV/HEV, and battery
charging systems.
The DMWSH120H28SM4Q operates at up to 1200VDS, +15/-4Vgs, and
has a lower RDS(ON) of 20 mΩ (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 (RθJC=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.
By using the planar manufacturing process, Diodes 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 AEC-Q101 qualified,
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.
