SUPPRESSOR FOR SLIC PROTECTION
FEATURES
DUAL PROGRAMMABLE TRANSIENT
SUPPRESSOR
HIGH SURGE CURRENT CAPABILITY.
- IPP = 50A, 10/1000 µs.
- IPP = 60 A, 5/310 µs.
- IPP = 150 A, 2/10 µs.
HOLDING CURRENT = 150 mA min.
LOW GATE TRIGGERING CURRENT :
IGT = 15 mA max.
DESCRIPTION
This device has been especially designed to
protect a subscriber line card interface (SLIC)
against transient overvoltage.
Positive overloads are clipped with two diodes,
while negative surges are suppressed by two
protection thyristors, their breakdown voltage
being is referencedto the -Vbat.
This component presents a very low gate
triggering current (IGT) in order to reduce the
current consumption on the PC board during the
firing phase.

FUNCTIONAL DESCRIPTION
LINE A PROTECTION:
- For positive surges versus GND, the diode D1
will conduct.
- For negative surges versus GND, the protec-
tion device P1 will trigger at a voltage fixed by
the -VBAT reference.
LINE B PROTECTION:
- For surges on Line B, the operating mode is the
same , D2 or P2 is activated.
A capacitor (C = 220nF) can be added close to
the gate of the LCP15xx, in order to speed up
the triggering.
