ABSTRACT:
A high-current, high-voltage solid state switch includes at least one solid state switching component connected to control circuitry configured into a single package. In the preferred embodiment, the switching component includes a power field effect transistor, and the control circuitry includes control logic, temperature sense and overcurrent circuits supported in an adjacent, coplanar relationship. Parallel coupled transistors are used for higher current embodiments.
