Wolfspeed HM3 High Power Modules

Wolfspeed HM3 High Power Modules are all-silicone carbide, switching optimized, low inductance modules in a low profile footprint (110mm x 65mm x 12.2mm). The HM3 components implement switching-optimized third-generation SiC MOSFET technology. A lightweight 62mm compatible ALSiC baseplate enables system retrofitting. Other features include a 175°C junction operation temperature and a high-reliability silicon nitride insulator. The Wolfspeed HM3 High-Performance Half-Bridge Modules are ideal for railway/traction, solar, EV charger, and industrial automation/testing applications.
