Choosing a suitable transient suppression diode to protect the circuit from overvoltage damage requires consideration of multiple factors. Here are some guiding steps: Voltage Level: Determine the maximum operating voltage and maximum overvoltage required for your circuit. The rated voltage of the transient suppression diode should be slightly higher than the maximum overvoltage to ensure its normal operation and effective suppression of overvoltage.

Transient Voltage Suppressor (TVS) is a special type of diode that works mainly based on the avalanche breakdown effect of PN junction. The following is a detailed introduction to its working principle: 1. Avalanche breakdown effect Avalanche breakdown effect is the core principle of TVS diode operation. The avalanche breakdown effect is the core principle of TVS diode operation. In a PN junction, when the applied voltage exceeds its breakdown voltage
