ABSTRACT:
A semiconductor device is fabricated which has reduced power dissipation when the device is turned on and runs cooler in surge suppressor applications. This result is achieved by fabricating a device where the breakdown action takes place preferentially under cathode region. The lower power dissipated during the turn-on action enables the device to operate in environmental conditions from -20.degree. C. to 65.degree. C.
