A varistor is a voltage-dependent resistor which has a nonlinear, non-symmetrical current-voltage characteristic that either allows a high current at a low voltage or blocks the current at a higher voltage. This type of device is also known as a voltage-dependent resistor (VDR) or a surge-protector component. Varistors are ideal for applications that require overvoltage protection or surge protection, such as power adapters, portable equipment, appliances, and automobiles.

VARISTOR 12ZA1 is a zinc-oxide-based varistor with the rated AC voltage of 500V. It is specifically designed for overvoltage protection in residential, commercial and industrial applications. The 12ZA1 is encapsulated in a vapor-phase epoxy body, which provides superior thermal performance, and is UL and RoHS compliant.

The 12ZA1 also features a low profile, light weight, and a low profile, making it ideal for applications with limited space. Additionally, it can be used in both AC and DC applications. Its excellent climate resistance allows it to be used both indoors and outdoors.

The working principle of the VARISTOR 12ZA1 is based on the nonlinear current-voltage characteristics of zinc oxide, which is commonly used in varistors. When voltage is lower than the rated voltage of the device, the resistance is extremely low and it allows high current to flow. On the other hand, when voltage is higher than the rated voltage, the resistance increases and blocks the current.

A varistor can also act as a static switch. When the voltage is higher than the breakdown voltage, it will short the circuit. This can be used to prevent overcurrents in an electronic circuit in the event of a voltage surge. The VARISTOR 12ZA1 is used in a wide variety of applications including over-current protection, over-voltage protection, surge protection, EMC filters, and more.

The VARISTOR 12ZA1 is an ideal solution for residential, commercial, and industrial applications requiring overvoltage protection or surge protection. This device features a low profile and is available in a variety of packages, making it easy to integrate into a variety of circuit designs. It is RoHS and UL compliant and has a high tolerance to both temperature cycling and shock. Additionally, it offers excellent climate resistance, making it suitable for both indoor and outdoor use.
