Varistors (VEsters) are semiconductor devices that can be used to protect systems against overvoltage or overcurrent problems. The V470ZA05P is a small-series varistor that offers superior protection performance and high reliability for AC line and DC line applications. This device is based on proven voltage varistor technology that has been tested and proven to provide reliable performance in a variety of applications.

The V470ZA05P is an MOV (Metal-Oxide Varistor) that can be used to help protect against voltage and over-current events. The device consists of a two-terminal device with a ceramic core containing zinc-oxide particles in suspension. The zinc-oxide absorbs the energy from a power surge and diverts it away from the protected circuit. The device is designed to dissipate the absorbed energy as heat quickly and safely.

The V470ZA05P has an operating voltage range of up to 700 volts. It is rated for breakover current up to 0.5A and maximum current up to 21A. The varistor has an insulation breakdown voltage of 6.7KV, and its rated peak current is 100A. The V470ZA05P also has an excellent surge absorption capability, with its peak pulse current being rated at 2450A and its surge absorption energy being rated at 1100 joules. This makes it highly effective at protecting delicate electronic components from overvoltage and overcurrent events.

The V470ZA05P varistor is highly suitable for a wide range of AC and DC applications. It is commonly used in switch mode power supplies, power supplies for computers and telecommunications systems, surge suppressors, motor speed controls, medical diathermy equipment, and vibration motors. It is also suitable for use in automotive and industrial circuits, providing superior protection against short duration transients.

The working principle of the V470ZA05P is simple and effective. When a surge of electricity passes through the device, the zinc-oxide particles inside the device absorb the energy. The energy is quickly dissipated as heat, with the MOV remaining stable and within normal electrical limits. This protects any sensitive components that are connected in the protected circuit, allowing them to continue functioning without any disruption.

The V470ZA05P is a versatile and robust varistor that is ideal for protecting circuits and systems against overvoltage or overcurrent damage. Its surge absorption capabilities and durable construction make it a great choice for many applications, and its wide operating range make it suitable for many different types of circuitry. Its simple and reliable working principle ensures that it will provide reliable protection for years to come.
