V22ZA3PX2855

Varistors, MOVs (metal oxide varistors), also known as transient voltage suppressors, are components used to protect sensitive electronic equipment against damaging voltage spikes or transient voltage. The V22ZA3PX2855 is one such varistor that is designed to protect against high speed surges and overvoltages.

The V22ZA3PX2855 has an operating voltage range from 6.5 V to 400 V with a maximum discharge current of 18 A. This varistor offers excellent high surge capability with a maximum surge current of 2000 A with a clamping voltage between 20 V and 600 V. It is designed with a ceramic body with a single tab termination, and is capable of withstanding a surge duration of up to 900 µs. The V22ZA3PX2855 is suitable for use in applications that require a high degree of protection from voltage spikes and overvoltages, such as solar panels, wind turbines, automotive components, LED lighting, and even household appliances.

The working principle of the V22ZA3PX2855 is fairly simple. When an AC signal exceeding the varistor\'s rated operating voltage is applied, the varistor acts as an open circuit and does not allow the current to pass through it. However, when the signal increases in voltage beyond the varistor\'s breakdown voltage, it begins to conduct and limits the voltage to the predetermined clamping voltage. This in turn reduces the peak voltage on the circuit, thereby preventing damage to the sensitive electronics.

The V22ZA3PX2855 is designed to reduce peak voltage and suppress transient voltages. It is a reliable, compact, and energy-efficient solution for protecting electronic systems from voltage spikes, ESD, and other transient voltage surges. Additionally, the V22ZA3PX2855 has a low capacitance, which makes it suitable for use in applications with high switching frequencies. This makes it an ideal solution for protecting sensitive electronic equipment from damage resulting from high-speed voltage surges.

In conclusion, the V22ZA3PX2855 metal oxide Varistor is a reliable and efficient solution for protecting electronic circuits from voltage spikes and overvoltages. It is suitable for a wide range of applications, including solar panels, wind turbines, automotive components, LED lighting, and household appliances. The varistor works on the principle of reducing the peak voltage to the predetermined clamping voltage, thereby limiting the impact of transient voltage surges and protecting the sensitive electronics from possible damage.
