V27ZC4

TVS (Transient Voltage Suppressors) Varistors, MOVs (Metal-Oxide Varistors) are an important component used in power systems, providing surge protection and preventing catastrophic damage to the system. The V27ZC4 is a commonly used TVS diode, used in many applications, that provide protection against high-power surges and spikes. In this article, we’ll cover the application fields and working principle of the V27ZC4.

The V27ZC4 is a three-terminal device with a high surge withstand capability. It is typically used for 12V, 24V, and as high as 48V applications and is capable of absorbing greater than 2000W of transient energy for a time period of 8/20s and a repetition rate of up to 10 times for repetitive puncture events. It is also designed for low leakage current and low clamp voltage. It can operate over a wide temperature range from -55 to 125C. This type of TVS device offers superior surge protection for many applications, as they are less prone to burnout or false triggering than other types of TVS.

The V27ZC4 TVS device provides protection in the following application fields: DC lines, automotive controllers, telephone lines, peripheral protection, portable medical equipment, and testing and measurement departments as well. It can be used in situations that involve lightning strikes, power surges, or other extremely powerful events. It can also be used for high voltage isolation and filtering, as well as high voltage circuit switching.

The V27ZC4 TVS diode works by sensing a surge or spike in voltage and directing the excess energy to a safe path through the TVS and away from the protected components. The device is connected in parallel to the sensitive node and provides a low impedance path for the system. It absorbs the transient energy by providing a nearly instantaneous path to ground. When the transient voltage or current reaches a certain threshold, the device will start to conduct, providing a low impedance path for the surge or spike, and protect the system from further damage. Once the transient is over, the device will automatically reset itself and return to its normal state.

In summary, the V27ZC4 is a three-terminal TVS device with a high surge withstand capability that is suitable for a wide range of applications, from DC lines to automotive controllers. It is designed to provide superior surge protection and low clamping voltage. It works by providing a low impedance path for the transient surge or spike to ground. The device can automatically reset itself once the transient is over, protecting the system from further damage.
