ABSTRACT:
A protection circuit including complementary bipolar transistors having collectors connected to an input and base and emitters connected together to a respective voltage source. The bipolar transistors are lateral transistors having a field plate over the base region and spaced laterally from the laterally spaced collector and emitter regions. The base may include increased impurity surface regions extending from the emitter and collector to the gate to increase the beta and decrease the collector-base breakdown.
