Metal Oxide Varistors
Varistor>05D180~751KJ Series
MOV
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.
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 Information
The MOV-05DxxxK Series of 5 mm 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 750 V and Vrms voltages
from 11 V to 460 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.

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.
