A semiconductor device for protecting loads from power surges includes a first resistor having a first end connected to a first supply terminal, a capacitor connected to a second end of the first resistor and a second supply terminal. There is a first transistor with a source connected to the first supply terminal and a gate connected to a point between the first resistor and the capacitor. A second resistor is connected between the drain of the first transistor and the second supply terminal, and a first diode is connected between the gate and the source of the first transistor. A second transistor has a drain connected to the first supply terminal, a source connected to the second supply terminal, and a gate connected to the drain of the first transistor. There is a second diode connected between the gate and the source of the second transistor.
