PROGRAMMABLE TRANSIENT VOLTAGE
SUPPRESSOR FOR SLIC PROTECTION
FEATURES
DUAL PROGRAMMABLE TRANSIENT SUP-
PRESSOR.
WIDE NEGATIVE FIRING VOLTAGE RANGE :
VMGL = -80V max.
LOW DYNAMIC SWITCHING VOLTAGES :
VFP and VDGL.
LOW GATE TRIGGERING CURRENT :
IGT = 5mA max.
PEAK PULSE CURRENT :
IPP = 30A for 10/1000µs surge.
HOLDING CURRENT :
IH = 150mA.
DESCRIPTION
This device has been especially designed to pro-
tect subscriber line card interfaces (SLIC) against
transient overvoltages.
Positive overloads are clipped with 2 diodes.
Negative surges are suppressed by 2 thyristors,
their breakdown voltage being referenced to
-VBAT through the gate.
This component presents a very low gate trigge-
ring current (IGT) in order to reduce the current con-
sumption on printed circuit board during the firing
phase.
A particular attention has beengiven to the internal
wire bonding. The ”4-point” configuration ensures
reliable protection, eliminating the overvoltage in-
troduced by the parasitic inductances of the wiring
(Ldi/dt), especially for very fast transients.

Surge
generator
This is a GO-NO GO test which allows to confirm the holding current (IH) level in a functional test circuit.
TEST PROCEDURE :
- Adjust the current level at the IH value by short circuiting the D.U.T.
- Fire the D.U.T. with a surge current : IPP = 10A, 10/1000µs.
- The D.U.T. will come back to the off-state within a duration of 50ms max.
