Double-base-connected bipolar transistors with passive components preventing accidental turn-on
Last updated:
Abstract:
The present application discloses new approaches to providing "passive-off" protection for a B-TRAN-like device. Even if the control circuitry is inactive, AC coupling uses transient voltage on the external terminals to prevent forward biasing an emitter junction. Preferably the same switches which implement diode-mode and pre-turnoff operation are used as part of the passive-off circuit operation.
