SiC Schottky Diodes Designed for Harsh Environments



With the release of the E-Series SiC Schottky diodes, Wolfspeed sets the standard for the rapidly growing field of on-board and off-board automotive applications and solar power inversion. This family of diodes is specifically designed to be robust and reliable in the harshest environments. As a result, the E-Series diodes are the industry’s first 1200V SiC diodes to be automotive-qualified and high-humidity/highvoltage/high-temperature tested.
