TVS (Transient Voltage Suppressor) diodes are components that are used to protect sensitive components such as semiconductors. They are designed to react to Voltage spikes and clamp the Voltage at a set amount before going into the circuit.
 
TYPICAL APPLICATIONS
Use in sensitive electronics protection against voltage
transients induced by inductive load switching and lighting
on ICs, MOSFET, signal lines of sensor units for consumer,
computer, industrial, and telecommunication.
