How to Select Transient Voltage Suppressors (TVS Diode) ?
TVS Diode Tutorial and Selection Procedure:
Transient voltage suppressors (TVS) are clamping devices that limit voltage spikes by low impedance avalanche breakdown of a rugged silicon PN junction.
They are used to protect sensitive components from electrical overstress.
When a transient appears in the circuit, the TVS becomes active, clamping it to a harmless level.
The symbol and characteristics of the TVS are given below:
