SIDACtor Device Selection Criteria

SIDACtor
®
Data Book and Design Guide
When selecting a SIDACtor device, the following criteria should be used:
Off-state Voltage (V
The V
the circuit that the SIDACtor device is protecting.
Example 1:
For a POTS (Plain Old Telephone Service) application, convert the maximum operating
Ring voltage (150 V rms) to a peak voltage, and add the maximum DC bias of the central
office battery:
Example 2:
For an ISDN application, add the maximum voltage of the DC power supply to the
maximum voltage of the transmission signal (for U.S. applications, the U-interface will not
have a DC voltage, but European ISDN applications may):
Switching Voltage (V
The V
voltage rating of the component it is protecting.
Example 1:
Example 2:
Peak Pulse Current (I
For circuits that do not require additional series resistance, the surge current rating (I
the SIDACtor device should be greater than or equal to the surge currents associated with
the lightning immunity tests of the applicable regulatory requirement (I
For circuits that use additional series resistance, the surge current rating (I
SIDACtor device should be greater than or equal to the available surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (I
