Abstract:
1. A method for manufacturing an electronic device with an integrated transient voltage suppressing (TVS) circuit comprising: connecting a triggering diode between an emitter and a collector of a first bipolar-junction transistor (BJT) with said triggering diode having a reverse breakdown voltage BV less than or equal to a BVceo of said first BJT where BVceo stands for a collector to emitter breakdown voltage with base left open; connecting a second BJT with said first BJT forming a SCR whereas said first BJT triggering a SCR current through said SCR for further limiting an increase of a reverse blocking voltage; and said step of connecting said triggering diode and said SCR is a step of forming said triggering diode and said SCR on an integrated circuit (IC) chip.
