Abstract
To provide a technique enabling stable protection of a switching element at the time of short circuit by suppressing jumping of the voltage Vge between a gate terminal and a reference potential terminal at the time of occurrence of short circuit. A power semiconductor module having at least an upper arm, includes: a Zener diode connected between a gate terminal and a reference potential terminal and provided on the outside of a semiconductor chip of a switching element and provided on an insulating substrate; a casing which houses the insulating substrate; and a plurality of external electrodes provided to the casing and connected to the gate terminal and the reference potential terminal.
