Inventor： James Paul DiSarro ,  Aravind Chennimalai Appaswamy ,  Zaichen Chen

IPC: H01L27/02 ,  H01L29/739 ,  H02H9/04

CPC classification number: H01L27/0262 ,  H01L29/7393 ,  H02H9/046

Abstract: An electrostatic discharge protection system with a node adapted to receive a signal and threshold detecting circuitry coupled to the node. The system includes an IGBT having an IGBT gate coupled to an output of the threshold detecting circuitry, a resistor coupled between an IGBT emitter of the IGBT and a low reference potential node, and a BJT having a BJT base coupled to the IGBT emitter.
