DUAL LINE PROGRAMMABLE TRANSIENT
A.S.D.TM
VOLTAGE SUPPRESSOR FOR SLIC PROTECTION
FEATURES
Dualline programmable transient suppressor
Wide negative firing voltage range : VMGL = -80V
Low dynamic switching voltages : VFP and VDGL
Low gate triggering current : IGT = 5mA max
Peak pulse current : IPP = 15 A (10/1000 µs)
Holding current : IH > 150 mA
DESCRIPTION
The LCDP1511D is a dual line protector which pro-
tects subscriber line interface circuits (SLIC)
against transient overvoltages.
Positive overvoltages are clamped with diodes to-
wards GND, while negative overvoltages are sup-
pressed by thyristors connected to GND. The
breakdown voltage of the thyristors is determined
by the voltage applied to the gate, generally -Vbat.
