Abstract
A power semiconductor device of the present invention comprises a voltage drive type power MOS transistor, a series connection of a first resistor and Zener diode, a second resistor, and a series connection of a third resistor and MOS transistor. The power MOS transistor has a gate, source and drain. A drain-to-source voltage of the power MOS transistor is applied across the series connection of the first resistor and Zener diode. A gate-to-source voltage of the power MOS transistor is applied across the second resistor. The gate-to-source voltage of the power MOS transistor is applied across a series connection of a third resistor and the MOS transistor. The MOS transistor has a gate, source and drain. The gate of the MOS transistor is connected to a node between the first resistor and the Zener diode.
