Overview
SIDACtors are thyristor devices used to protect sensitive circuits from electrical
disturbances caused by lightning and AC power cross conditions. The unique structure
and characteristics of the thyristor are used to create an over-voltage protection device
with precise and repeatable turn-on characteristics with low voltage overshoot and
high surge current capabilities.
Key Parameters
Key parameters for SIDACtors are V
DRM
, I
DRM
, V
S
, I
H
, and V
T
. V
DRM
is the repetitive
peak off-state voltage rating of the device (also know as stand-off voltage) and is the
continuous peak combination of AC and DC voltage that may be applied to the
SIDACtor in its off-state condition. I
DRM
is the maximum value of leakage current that
results from the application of V
DRM
. Switching voltage (V
S
) is the maximum voltage
that subsequent components may be subjected to during a fast rising (100V/μs) over-
voltage condition. Holding current (I
H
) is the minimum current required to maintain the
device in the on-state. And on-state voltage (V
T
) is the maximum voltage across the
device during full conduction.

Operation
The SIDACtor operates much like a switch. In the off-state, the device exhibits leakage
currents (I
DRM
) less than 5μA making it invisible to the circuit it is protecting. As a
transient voltage exceeds the SIDACtors V
DRM
, the device will begin to enter its
protective mode with characteristics similar to an avalanche diode. When supplied with
enough current (I
S
), the SIDACtor will switch to an on-state, shunting the surge from
the circuit it is protecting. While in the on-state, the SIDACtor is able to sink large
