The V620ZA05 is a varistor (voltage-dependent resistor) that is commonly used in surge suppressors, transient voltage surge suppressors (TVSs), and other similar protective device applications. The device is a small, metal-oxide-based resistor that is capable of providing protection against overvoltage transients. The device has a capacitance value of 2.2pF with a breakdown voltage of 95V.

A varistor is a semiconductor device that is designed to provide protection from overvoltages by limiting the voltage transient to safe levels. The device uses a metal oxide film as the resistance medium to rapidly absorb and reduce peak voltages. The varistor responds rapidly to any sudden increase in the voltage, as the current of the voltage transient flows through the device. The metal oxide film behaves like a resistor, increasing its resistance with increased voltage, thus limiting the peak current and eventually the voltage.

When an overvoltage transient occurs, the varistor will act first as a resistor, thus limiting the peak current that flows through the device. As the voltage increases further, the resistance will also increase automatically, further limiting the peak current. The device will thereby limit the voltage transient to a safe level and prevent any damage from occurring to the subsequent circuitry. This protects against overvoltage transients such as ESD, lightning, and associated power surges or spikes.

The V620ZA05 has a maximum clamping voltage of 95V and a peak current rating of 230mV. The device has an operating temperature range of -55°C to 85°C. Its small size is ideal for a wide range of applications, such as audio-visual equipment, personal computers, telecommunications equipment, and any other application that requires surge protection. The device is designed with a long shelf life and high reliability, offering long-term protection from overvoltage transients.

The V620ZA05 is a highly reliable varistor that can provide effective protection from overvoltage transients. Its small size and wide range of capabilities make it a great choice for a range of applications in need of surge protection. This device is a perfect choice for any application requiring fast and reliable protection against damaging overvoltage transients.
