| Zusammenfassung: | The present application discloses a transient diode failure monitoring circuit, and relates to the technical field of circuit protection. A differential amplification module and a voltage sampling module of a circuit are electrically connected to a transient diode, and when the transient diode is switched from a high-resistance state to a low-resistance state, an operational amplifier in the differential amplification module obtains a diode active signal, a statistical module is electrically connected to the differential amplification module, and the statistical module counts working times signals of the transient diode according to the diode active signal and outputs an aging signal of the transient diode.
