ABSTRACT:
A Silicon-Controlled Rectifier (SCR) for Electrostatic Discharge (ESD) protection includes an isolation device. The isolation device isolates a main ground voltage line, connected to a first cathode, from a peripheral ground voltage line, connected to a second cathode. As result, even when noise occurs in the peripheral ground voltage line during the operation of an integrated circuit, the main ground voltage line maintains a stable voltage level.
