Introduction

In the realm of electronics, ensuring the stability and longevity of circuits is paramount. One component that plays a pivotal role in safeguarding electronic devices against voltage spikes and transient events is the Transient Voltage Suppressor Diode (TVS diode).

Understanding Transient Voltage Suppressor Diodes

Transient Voltage Suppressor Diode commonly known as TVS diodes, are semiconductor devices designed to protect sensitive electronic components from voltage spikes and transient surges. These surges can result from various sources such as lightning strikes, electromagnetic interference, or switching events within the circuit.

Working Principle

At their core, TVS diodes operate by rapidly conducting excess current away from the protected circuit when a voltage surge occurs. They achieve this through a mechanism called avalanche breakdown or Zener breakdown. During a surge, the diode enters a state of low impedance, effectively clamping the voltage across the circuit to a safe level, thus protecting downstream components.
