SIDACtor Device Selection Criteria

[phone]
The maximum available surge current is calculated by dividing the peak surge voltage (V
by the total circuit resistance (R
For longitudinal surges (Tip-Ground, Ring-Ground), R
Ring:
For metallic surges (Tip-Ring):
Example 1:
A modem manufacturer must pass the Type A surge requirement of TIA-968 (formerly
known as FCC Part 68) without any series resistance.
Example 2:
A line card manufacturer must pass the surge requirements of GR 1089 with 30 W on Tip
and 30 W on Ring.
Holding Current (I
Because TIA-968 4.4.1.7.3 specifies that registered terminal equipment not exceed
140 mA dc per conductor under short-circuit conditions, the holding current of the SIDACtor
device is set at 150 mA.
For specific design criteria, the holding current (I
than the DC current that can be supplied during an operational and short circuit condition.
