Wolfspeed

Wolfspeed’s wide bandgap semiconductor products for power and radio-frequency (RF) applications deliver new levels of performance through increased efficiency, higher switching frequency and reduced system size and weight for the transportation, industrial and electronics, energy and communications markets.

Please refer to www.wolfspeed.com for additional product and company information.

Wolfspeed is the world’s leading manufacturer of silicon carbide-based diodes and switches for power control and conversion. These devices provide increased efficiency and enable higher switching frequency to minimize system size, weight and cost. Applications include:

  • Power factor correction
  • Solar inverters
  • Industrial motor drivers
  • Output rectification
  • Power modules
  • Traction inverters

Auxiliary power supplies
Since 2011, Wolfspeed, Inc. has partnered with Semi Dice, Inc. for sole distribution of Wolfspeed’s silicon carbide based power products in wafer and bare die form. Wolfspeed’s family of Z-Rec ® rectifiers has essentially no reverse recovery at 600V, 650V, 1200V and 1700V breakdown and is targeted for applications where low switching loss is required.

Wolfspeed introduced the industry’s first SiC MOSFETs in 2011. Their family of Z-Fet® MOSFETs provide the highest energy efficiency and fastest switching speeds versus any comparable silicon power switch.

Wolfspeed hasn’t stopped innovating. In March 2013, they have released their 2nd-generation MOSFETs, which provided even higher efficiency and reduced size combined with industry-leading power density at half the cost-per-amp of the 1st-generation. Most recently, in February 2014, Wolfspeed announced the full release of their CPW5 family of Z-Rec® Schottky diodes.These advanced silicon carbide diodes deliver the highest current-carrying capability and surge resistance among all commercially available SiC rectifiers.
