TVS - Varistors, MOVs (V22ZT05PX2855) are high performance over-voltage protection components, specifically designed to protect critical electronic systems from over-voltage damages (surges, spikes, ESD, EFT).

V22ZT05PX2855 is a professional high performance over-voltage protection components, specifically designed to protect critical electronic systems from over-voltage damages (surges, spikes, ESD, EFT). It is an Zener-diode based device which utilizes the superior clamping performance of Zener-diode combined with the excellent transient current capacity of MOV (Metal Oxide Varistor). It also provides multiple ground paths to ensure an enhanced ability to dissipate surge energy and helps reduce overall surge countermeasures.

The V22ZT05PX2855 contains an advancement over traditional diode-based devices, encompassing two layers of protection. The first layer utilizes Zener-diode to provide fast clamping action, rendering the second layer, which is MOV (Metal Oxide Varistor), unnecessary for most applications. But, when higher surge currents are encountered, the second layer will activate and dissipate the extra surge energy.

V22ZT05PX2855 features multiple ground paths to provide an enhanced ability to dissipate surge energy. Its unique design provides extremely low capacitance when compared to many other available voltage protection devices. The main advantages are its low capacitance, wide operating voltage range, and fast response time. It also has high surge current capability and excellent reliability.

The V22ZT05PX2855 is most suitable for applications that require higher speed, low capacitance, and pulse power protection. It is widely used in data lines, telecom lines, power lines, computers, and consumer electronic equipment to provide over-voltage protection. It is ideal for applications where high energy transient over-voltage protection and low capacitance is critical.

V22ZT05PX2855 working principle is designed around a 0.5V Zener-diode together with a high current Metal Oxide Varistor (MOV). If the applied voltage exceeds the Zener voltage, the Zener-diode conducts and short-circuits the input to ground. In such cases, the current is limited by the very low series resistance of the Zener-diode. The Zener-diode will clamp the over-voltage to the Zener voltage and protect the circuit. If the over-voltage is higher and the MOV is activated, it will provide additional surge current protection and dissipate the extra energy.

In summary, V22ZT05PX2855 is a high performance over-voltage protection components, specifically designed to protect critical electronic systems from over-voltage damages (surges, spikes, ESD, EFT). It provides multiple ground paths to ensure an enhanced ability to dissipate surge energy and helps reduce overall surge countermeasures. The main advantages are its low capacitance, wide operating voltage range, and fast response time, which makes it the ideal choice for applications where high energy transient over-voltage protection and low capacitance is critical.
