Abstract:
An ESD protection circuit including an SCR having at least a PNP transistor and at least a NPN transistor such that said PNP transistor is coupled to an anode and the NPN transistor is coupled to a cathode. The circuit also includes a first resistor coupled between the anode and the base of the pnp transistor and a second resistor coupled between the cathode and the base of the npn transistor. A parasitic distributed bipolar transistor is formed between said first and second transistor to control triggering of the SCR.
