DESCRIPTION
SIP 4
SCHEMATIC DIAGRAM
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 (I
GT
) in order to reduce the
current consumption on the PC board during the
firing phase.
