Description
Transient Voltage Suppressor (TVS) is a circuit protection
component that either attenuates (reduces) or filters a
transient voltage spike (overvoltage), TVS diodes provide
critical protection by going into avalanche breakdown
within no more than a few nanoseconds after a strike,
clamping the transient voltage, and routing its current to
the ground.
