Metal Oxide Varistors

Varistor>25D180~182KJ Series

Applications

• Transistor, diode, IC, thyristor or triac semiconductor protection.

• Surge protection in consumer electronics.

• Surge protection in industrial electronics.

• Surge protection in electronic home appliances, gas and

petroleum appliances.

MOV

• Relay and electromagnetic valve surge absorption.

Features

• Wide operating voltage (V1mA) range from 8V to 1800V.

• Fast responding to transient over-voltage.

• Large absorbing transient energy capability.

• Low clamping ratio and no following-on current.

General Characteristics

General Information

The MOV-25DxxxK Series of 25mm radial leaded varistor devices

protects against overvoltage transients such as lightning, power

contact and power induction. The metal oxide varistors offer a

choice of varistor voltages from 18 V to 1800 V and Vrms voltages

from 11 V to 1000 V.

The devices have a high current handling, high energy absorption

capability and fast response times to protect against transient

faults up to rated limits.

device. The operating values of a MOV need to be derated

at high temperatures as shown above. Because varistors

only dissipate a relatively small amount of average power

they are not suitable for repetitive applications that involve

substantial amounts of average power dissipation.

Should transients occur in rapid succession, the average

times the number of pulses per second. The power so

developed must be within the speciﬁcations shown on the
