Abstract
A switching circuit includes: a transistor having a first electrode, a second electrode and a control electrode; a zener diode; and a capacitor. A connection between the first electrode and the second electrode is capable of temporally switching between a condition state and a non-conduction state by switching a control voltage of the transistor. The zener diode and the capacitor are coupled in series between the first electrode and the control electrode of the transistor. The first electrode is a drain or a collector.
