Transient voltage suppression diode, also known as a TVS diode, is a protective electronic component that protects electrical equipment from voltage spikes introduced by wires.
TVS diodes are placed in parallel with the circuit to be protected. When its voltage exceeds the burst breakdown level, excessive current is directly shunted. TVS diodes are clamps that suppress excessive voltages that exceed their breakdown voltage. When the overvoltage disappears, the TVS diode automatically resets and absorbs much more energy than a similarly rated crowbar circuit.
