Applications Information (continued)
Protecting One SLIC Line Pair
The TC03A-200 battery tracking TransClamp is specifi-
cally designed to protect subscriber line interface
circuits (SLICs). The protection voltage of the device is
referenced to the system’s DC battery voltage. There-
fore, the protection voltage will be essentially the same
as the SLIC supply voltage, minimizing the stress on
the protected device. The TC03A-200 may be refer-
enced to battery voltages ranging from -5V to -100V.
Pin 1 is connected to the line (A-lead or B-lead). The
battery feed voltage source is connected to the gate of
the internal SCR at pin 3. Pin 2 is connected to
ground. A 0.1F capacitor is recommended between
the gate & ground to speed up the triggering of the
device.

Protecting Multiple SLIC Lines
The TC03A-200 may be used in conjunction with
steering diodes to protect up to two SLIC Tip & Ring
line pairs. The steering diodes shunt positive surges to
ground. In this configuration, each line pair may be
surged to 100A (tp=10/100s) independantly, or all
four pairs may be surged simultaneously up to 50A
(tp=10/100s). This provides the designer with a
flexible, cost effective solution and increased reliability
over low current protection schemes.
