1、穩(wěn)壓二極管的穩(wěn)壓原理：穩(wěn)壓二極管的特點(diǎn)就是擊穿后，其兩端的電壓基本保持不變。這樣，當(dāng)把穩(wěn)壓管接入電路以后，若由于電源電壓發(fā)生波動，或其它原因造成電路中各點(diǎn)電壓變動時，負(fù)載兩端的電壓將基本保持不變。
2、故障特點(diǎn)：穩(wěn)壓二極管的故障主要表開路、短路和穩(wěn)壓值不穩(wěn)定。在這3種故障中，前一種故障表現(xiàn)出電源電壓升高；后2種故障表現(xiàn)為電源電壓變低到零伏或輸出不穩(wěn)定。

1, the voltage regulation principle of the voltage regulator diode: the characteristic of the voltage regulator diode is that after breakdown, the voltage at both ends remains basically unchanged. In this way, when the regulator is connected to the circuit, if the power supply voltage fluctuates, or the voltage changes at each point in the circuit for other reasons, the voltage at both ends of the load will remain basically unchanged.
2, fault characteristics: the main failure of the voltage regulator diode is open circuit, short circuit and unstable voltage regulator value. Among these three faults, the former one shows that the power supply voltage increases; The latter two failures are manifested as the supply voltage becomes low to zero volts or the output is unstable.
