TVS (Transient Voltage Surge) products are an industry standard for protecting equipment from dangerous electric overshoots and lightning induced voltage spikes. The V120ZC6 is a widely used, high performance TVS component that offers protection from lightning induced overshoots, as well as an ideal combination of trade-offs between surge current and voltage protection.

Application Field

V120ZC6 is primarily used to protect equipment against high-voltage transients found in the powergrid, such as lightning induced voltage spikes. This device is designed to clamp the voltage of transients that exceed its trigger voltage rating and absorb the surge current safely, without affecting the normal operation of the equipment. Other applications include protection of sensitive device noise, such as protection from ground bounce noise generated by high speed logic signals.

Electrical Characteristics

The V120ZC6 has a fail-safe behavior where at greater than 1.5kV it will open up quickly to reduce the risk of fire. This product has an excellent response time, with a Trigger Voltage Rating of 600V and Typical Voltage Rating of 540V, meaning that it will open up fast enough to protect a device from most medium voltage spurious transients. This product has a high surge withstand capability, allowing it to adequately protect from lightning surges and other high voltage spikes without significantly degrading its performance. These features make it suitable for use in both residential and commercial applications.

Working Principle

Like other TVS components, the V120ZC6 is designed to clamp the voltage of transients that exceed its trigger voltage rating. The device works by using a semiconductor junction with an overvoltage protection feature. The device is designed to turn on when a high voltage transient occurs, and then quickly clamp the voltage and displace the surge current. The device will quickly turn off once the surge current has passed, allowing the equipment to resume normal operation. This device has the added safety advantage of using a fail-safe behavior where, at greater than 1.5kV, it will open up quickly, further reducing the risk of fire.

Conclusion

The V120ZC6 is a widely used, high performance TVS component that offers excellent protection from high voltage transients, such as lightning induced voltage spikes. The device has an excellent response time and offers excellent surge current and voltage protection. The device is also designed to have a fail-safe behavior, where it will open up quickly at a greater than 1.5kV to reduce the risk of fire, making it suitable for both residential and commercial applications.
