TVS diodes are used as a means of protecting electronic circuits from voltage spikes. The acronym itself stands for Transient Voltage Suppressor.
Basic Operation
A TVS diode is attached in parallel to an electronic circuit that needs to be protected. Because of the flow of electricity through the circuit, it receives the same amount of voltage as does the protected electric circuit.
When the circuit is functioning normally, a small trickle of electricity flows through the diode, but it is insignificant enough that it doesn
