The Transient Voltage Suppressor diode (TVS Diode) is a protection diode designed to protect electronic circuits against transients and overvoltage threats such as EFT (electrically fast transients) and ESD (electro-static discharge). TVS Diodes are silicon avalanche devices and are widely used in home appliances, entertainment devices, telecom equipments and other devices because of their fast response time, excellent voltage clamping ability, lower capacitance and low leakage current characteristics. Polytronics TVS diodes are available for both uni-direction and bi-direction in different packaging sizes, wide working voltage range and wide power range.
