Wolfspeed Achieves Industry’s First All-SiC 1.2kV power Module Reliability Benchmark for Harsh Environment Operation

New SiC power module enables highest
reliability SiC devices for outdoor systems in renewable energy and
transportation
Wolfspeed, a Cree Company and a leader in silicon carbide (SiC)
power products, extends its leadership in SiC power device
technology with the release of the industry’s first power module
that passes the harsh environment qualification test for
simultaneous high-humidity, high-temperature and high-voltage
conditions.
This reliability benchmark enables system designers to use this
device in outdoor applications such as transportation, wind, solar
and other renewables where extreme environmental conditions have
historically challenged safe device operation. The new all-SiC
module, rated for 300 A and 1.2 kV blocking, was stressed in an 85
percent relative humidity, 85°C ambient while biased at 80 percent
of rated voltage (960V). Success in harsh environment testing under
bias provides further confidence in the overall ruggedness of SiC
device technology for all applications.
“SiC components enable the design of compact, lightweight,
low–loss converters required for railway transport applications,”
said Michel Piton, semiconductor master expert at Alstom, a leading
global supplier of systems, equipments and services for the railway
market. “Achieving March 2017 the benchmark for temperature and
humidity under high bias voltage is a key milestone for SiC devices
in its adoption into our demanding market.”
Powered by new Wolfspeed™ MOSFETs (CPM2-1200-0025A) and Gen5
Schottky diodes that also pass the harsh environment test at the
die level, the new module retains the low 4.2 mΩ on-resistance and
more than five times lower switching losses than similarly rated,
latest generation IGBT modules. Module construction utilizes high
thermal conductivity aluminum nitride substrates and optimized
assembly methods to meet industry thermal and power cycling
requirements.
“This device is yet another industry-first driven by Wolfspeed,”
said John Palmour, Wolfspeed’s chief technology officer. “The
latest 1200V module demonstrates our commitment to enabling markets
and applications by meeting the anticipated system requirements for
2020 and beyond.”
Available under part number WAS300M12BM2, the new module can be
driven using existing Wolfspeed™ gate drivers for 62mm modules.
