General Characteristics
General Information
The MOV-07DxxxK Series of 7 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 820 V and Vrms voltages
from 11 V to 510 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
Device Ratings and Specifications Table for the specific
