TVS – Varistors, MOVs devices are the semiconductor components used to protect circuits from transient overvoltage. A common TVS device is ERZ-E11A331CS, which is designed to protect systems from high-voltage transients. The device has a breakdown voltage of 331V, a clamping voltage of 375V, and a peak pulse surge current rating of 10500Amps. The application field of ERZ-E11A331CS can include telecom equipment, automotive electronics, consumer electronics, and anywhere a transient voltage protection solution is needed.

When it comes to the working principle of ERZ-E11A331CS, its primary function is to absorb and divert any excessive voltage transient before it can damage circuits and components. The device is composed of a metal oxide varistor (MOV) inside, with two metal or plastic terminals on either side. When the device is connected between two nodes of a circuit, no current will flow through it, until a voltage transient exceeding its breakdown voltage is applied, at which point, it will conduct current and relieve the overvoltage.

The quick response of the MOV device will safely absorb excessive voltages, while the chip remains low leakage current and low capacitance. As soon as the transient voltage has passed, the MOV immediately goes back to its original state and resumes its open-circuit voltage. The device has high surge current capability and good heat dissipation. It also has excellent ESD protection performance and is simple to use.

ERZ-E11A331CS is a cost-effective, space-efficient solution to provide surge protection against high-amplitude voltage transients. The device is ideal for applications where there is not enough room for a full-size TVS diode solution, and can be used in both low voltage and high voltage circuits for maximum protection. With its small size, low power consumption, and quick response time, the device offers superior protection to ensure reliable and consistent operation of the system.
