V120ZT05PX2855

A Varistor is a voltage-dependent Resistor (VDR) used to protect electrical circuits from high-voltage shock, overvoltages, overcurrents, and overpowers. This makes it an incredibly useful device for a variety of applications. The V120ZT05PX2855 is a Varistor manufactured and marketed by Littelfuse, and it is designed specifically for use in protecting delicate electronic circuits.

The V120ZT05PX2855 Varistor offers impressive surge-current protection, with an average maximum clamping voltage of 330V at a 1.2/50 surge of 8/20μs. It has a peak surge current capability of 40A and a minimum breakdown voltage of 90V. It is designed with a bidirectional electrical flow, allowing it to function effectively in both AC and DC circuits.

The Varistor is a small, cylindrical component that can be used in a variety of applications. It is commonly used in consumer electronics, automotive electronics, industrial machinery, and teletronics. It can be used to protect delicate circuits from high voltage surges, current transients, and inrush current. It can also be placed in between power supplies and the ground for added protection against electrical overloads.

The Varistor’s working principle is based on its voltage-dependent behavior. When exposed to a higher voltage level than its breakdown voltage, the Varistor acts as a low-resistance shunt across the circuit, allowing it to pass the energy to the ground and thereby protect the underlying circuit. The Varistor also has a current-limiting characteristic, allowing it to protect from both over-voltage and over-current events. This makes it an ideal device for protecting sensitive equipment from electrical over-voltages.

As the demand for consumer electronics, automotive electronics, industrial machinery, and teletronics continues to grow, the need for reliable surge protection solutions is becoming increasingly important. The V120ZT05PX2855 Varistor is a great option for providing surge protection, thanks to its impressive maximum clamping voltage and surge current capabilities. Its small size and bidirectional electrical flow make it ideal for use in a variety of applications, making it a great choice for protecting your sensitive electronic circuits.
