Field plates on two opposed surfaces of double-base bidirectional bipolar transistor: devices, methods, and systems

Last updated:

Abstract:

Dual-base two-sided bipolar power transistors which use an insulated field plate to separate the emitter/collector diffusions from the nearest base contact diffusion. This provides a surprising improvement in turn-off performance, and in breakdown voltage.
