Abstract:  An apparatus and method is disclosed for providing an electrostatic discharge protection circuit for compound semiconductor devices and circuits. The electrostatic discharge protection circuit comprises a first terminal and a second terminal. The electrostatic discharge protection circuit further comprises a transistor shunt element that is operably coupled between the first terminal and the second terminal; the transistor shunt element is capable of providing a bi-directional discharge path between the first terminal and the second terminal. The electrostatic discharge protection circuit further comprises a shut-off element that is operably coupled with the second terminal; the shut-off element is capable of keeping the transistor shunt element turned-off.
