Electric load control circuit uses n-channel MOSFET protected by Zener diode connected across its switched current path and diode between its gate and earth

摘要

The load control circuit (10) uses a n-channel MOSFET (Tr0) acting as a high-side switch for supplying the current to the electric load (4), with a Zener diode (ZD1) between the drain and source of the MOSFET and a diode (D1) connected between the gate of the MOSFET and earth.
