TVS Diodes

A ‌Transient Voltage Suppression (TVS) diode‌ is a specialized semiconductor device designed to protect sensitive electronics from ‌sudden voltage spikes‌ (e.g., electrostatic discharge/ESD, lightning strikes, or switching surges). It operates by rapidly diverting excess current away from protected circuits, clamping the voltage to a safe level within nanoseconds. Unlike standard diodes, TVS diodes feature ‌larger PN junctions‌ to handle high-energy transients without damage‌

Core Working Principle‌:

‌1. Reverse Standby State:

In normal operation (voltage < breakdown threshold), the TVS diode acts as an open circuit with minimal leakage current.

2‌. Clamping During Surge:

When a transient voltage exceeds the ‌reverse breakdown voltage(typically 5V–495V), the diode instantly switches to a low-impedance state, shunting current to ground and limiting voltage across the protected circuit‌

3.Self-Recovery:

After the surge passes, it automatically resets to standby mode.
