An electrostatic discharge (ESD) protection device is provided. The apparatus includes: a double diffused drain N-type metal oxide semiconductor field effect transistor (MOSFET); a P-type silicon controlled rectifier (SCR); a double diffused drain P-type MOSFET; and an N-type SCR, wherein: the double diffused drain N-type MOSFET is connected in parallel with the P-type SCR between an output pad and a first voltage pad; the double diffused drain P-type MOSFET is connected in parallel with the N-type SCR between the output pad and a second voltage pad; and the N-type SCR is connected in parallel with the P-type SCR between the first voltage pad and the second voltage pad.
