A solid state relay and method for enabling and disabling power to a load are disclosed. A fast turn-on circuit and fast turn-off circuit receive control signals in an isolated manner. The control signals allow only one of the fast turn-on circuit and fast turn-off circuit to be enabled at a time. A power switching circuit that enables power to be supplied to a load when the fast turn-on circuit is enabled and the fast turn-off circuit is disabled state, and disables the power from being supplied to the load when the fast turn-on circuit is disabled and the fast turn-off circuit is enabled. A power supply circuit provides isolated power used by the fast turn-on and fast turn-off circuits to drive or discharge a gate in the power switching circuit. |
