OVERVOLTAGE GUARD FOR ELECTRONIC CIRCUITS |
摘要 |
An overvoltage guard for electronic circuits protects the connections from voltage transients which exceed the supply voltage of the circuit. The transients are bypassed to the grounded terminal of the supply voltage source by a thyristor connected between the terminal and the grounded terminal, the gate electrode of the thyristor being connected to the ungrounded terminal via a diode. Between the terminal and the grounded terminal there is conventionally connected a limiting diode. |
