ABSTRACT:
A silicon-controlled rectifier (SCR) device having a high holding voltage includes a PNP transistor and an NPN transistor, each transistor having both p-type and n-type dopant regions in their respective emitter areas. The device is particularly suited to high voltage applications, as the high holding voltage provides a device which is more resistant to latchup subsequent to an electrostatic discharge event compared to devices having a low holding voltage.
