WIDE BANDGAP DEVICE IN PARALLEL WITH A DEVICE THAT HAS A LOWER AVALANCHE BREAKDOWN VOLTAGE AND A HIGHER FORWARD VOLTAGE DROP THAN THE WIDE BANDGAP DEVICE

摘要

A method and device for protecting wide bandgap devices from failing during suppression of voltage transients. An improvement in avalanche capability is achieved by placing one or more diodes, or a PNP transistor, across the blocking junction of the wide bandgap device.
