RA Varistor Series
The RA Series transient surge suppressors are varistors (MOVs)
supplied in a low-profile box that features a precise seating plane to
increase mechanical stability for secure circuit-board mounting. This
feature makes these devices suitable for industrial applications critical
to vibration. Their construction permits operation up to 125oC (ambient)
without derating.
2
The RA series are available in voltage ratings up to 275V V
,
M(AC)RMS
and energy levels up to 140J. These varistors are used in automotive,
motor-control, telecommunication, and military applications.
See RA Series Device Ratings and Specifications table for part number
and brand information.

Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipation
required is simply the energy (watt-seconds) per pulse times the number
of pulses per second. The power so developed must be within the specifi-
cations shown on the Device Ratings and Specifications table for the
specific device. Furthermore, the operating values need to be derated
at high temperatures as shown in Figure 1. Because varistors can only
dissipate a relatively small amount of average power they are, therefore,
not suitable for repetitive applications that involve substantial amounts of
average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified current) of more than ±10% could result.This type of shift, which normally results in a decrease of V ,
N(DC)
may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
