Wolfspeed Introduces New SiC MOSFET for EV Drive Trains

New 900V, 10mΩ chip enables new improvements in
range, battery usage and vehicle design
Wolfspeed, a Cree Company and a leader in silicon carbide (SiC)
power products, has introduced a 900V, 10mΩ MOSFET rated for 196 A
of continuous drain current at a case temperature of 25̊̊ C. This
device enables the reduction of EV drive-train inverter losses by
78 percent based on EPA combined city/highway mileage standards.
This efficiency improvement offers designers new options in terms
of range, battery usage and vehicle design.
Recently Wolfspeed supplied Ford Motor Company―in a
collaboration with the U.S. DoE―with a full-SiC, 400A power module
designed around the 900V, 10mΩ chip. The module, designed and
produced by Wolfspeed, contains four MOSFETs connected in parallel
to achieved a remarkable 2.5mΩ Rds(on). Wolfspeed engineers have
since demonstrated the capability to use these chips to create an
800A, 1.25mΩ module.
“With the commercial release of the 900V 10mΩ device, electric
vehicles can now reap the benefits of SiC in all aspects of their
power conversion,” said John Palmour, CTO of Wolfspeed. “With
the continued expansion of our Gen3 MOSFET portfolio in new package
options, our devices can now support significant efficiency
improvements in onboard chargers, offboard chargers, and now EV
drive trains.”
Commercially qualified and rated for a maximum operating
temperature of 175˚C, Wolfspeed’s new chip offers high-reliability
in harsh environments, like those found in vehicle
drive-trains.
Device Information
The new 900V, 10mΩ MOSFET is available in bare die, is listed as
part number CPM3-0900-0010A, and is currently available
for purchase from SemiDice. Wolfspeed expects to release the
associated discrete device in a 4L-TO247 package (C3M0010090K) in
the coming weeks. This package has a Kelvin-source connection that
allows engineers to create designs that maximize the benefits of
SiC’s superior speed and efficiency.
