Understanding TVS Diode Operation and Selection

TVS diodes are protection devices designed to clamp high-energy voltage transients before they can damage sensitive circuitry. Proper device selection requires matching working voltage, breakdown voltage, clamping voltage, and peak pulse power to the expected surge conditions.

Understanding how parameters such as VRWM, VBR, and VC interact is essential to ensure effective protection without overstressing downstream components.
