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.

Current Energy and Power Dissipation Ratings
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
Device Ratings and Specifications Table for the specific
