Power bjt device with single pulse current strong turn-off capability, circuit breaker, and method

Abstract

A power BJT device with single pulse current strong turn-off capability, a circuit breaker, and a method are disclosed, in the power BJT device with single pulse current strong turn-off capability, an N-type drift region is laminated on a substrate, a P-type base region is laminated on the N-type drift region, at least one N-type region is arranged on the P-type base region, a collector is arranged on the N-type substrate as a power lead-out electrode, an emitter is arranged on the N-type region as a power lead-out electrode, a base is arranged on the P-type base region without contacting the N-type region as a control lead-out electrode, and a drive circuit is connected with the base to control the turn-on and turn-off of the power BJT device.

Dependencies are inferred from the claim text.
