DEFINITION

Classification: 257/143

Having anode shunt means:

(under subclass 139) Subject matter wherein the extended latchup current level device has means connected across the emitter-base junction of the PNP transistor portion of the regenerative device to controllably divert current from the emitter-base junction.
