TVS - Diodes

A Transient Voltage Suppression (TVS) diode, also referred to as a Transient Voltage Suppressor (TVS), is a two-terminal solid-state device composed of an integrated circuit with a breakdown voltage that can suppress and divert high-voltage electrical transients away from sensitive components. They are commonly used to protect circuitry from electrostatic discharge (ESD), lightning, and induced transients from switching operations. This protection is typically provided with a TVS diode that can be placed near the susceptible component and configured to be triggered by a rapid voltage rise.

PTVS22VZ1USKYL application field and working principle

The PTVS22VZ1USKYL is a unidirectional transient voltage suppressor, designed for protection from hazardous transient voltage. This component is designed to protect sensitive electronics from ESD, EFT, and lightning surges. The component has a two-terminal construction with a high blocking voltage rating of up to 22V. The PTVS22VZ1USKYL is a versatile device that can be used in a variety of applications.When a transient voltage comes into contact with the PTVS22VZ1USKYL, the device quickly switches on and limits the voltage to a safe point. Through dynamic avalanche breakdown, the diode is activated and provides a rapid and safe clamping action that reduces the voltage to the pre-select threshold voltage. After the transient has dissipated, the device’s on-state voltage can return to its low value.The PTVS22VZ1USKYL offers a high surge capacity, making it ideal for use in stereo and HDMI cables that transport high-resolution digital audio and video signals. The device features high surge capacity and low leakage current, which ensures high signal integrity and reliability. The PTVS22VZ1USKYL also helps protect sensitive electronics from high-voltage surges caused by nearby lightning strikes. The device can also be used to protect audio systems and electrical appliances, such as LCD televisions, from voltage transients from power supplies or other electrical sources.In summary, the PTVS22VZ1USKYL is a versatile and reliable transient protection device. Its high surge capacity, low leakage current, and protective functions make it an ideal solution for a wide range of applications.
