LCP1521S/LCP152DEE
ASD (Application Specific Devices)
Programmable transient voltage suppressor for SLIC protection
Features
Dual programmable transient suppressor
Wide negative firing voltage range:
VMGL = -150 V max.
Low dynamic switching voltages:
VFP and VDGL
Low gate triggering current: IGT = 5 mA max
Peak pulse current: IPP = 30 A (10/1000 µs)
Holding current: IH = 150 mA min
Low space consuming package
Description
www.DataSheet4U.com
These devices have been especially designed
to protect new high voltage, as well as classical
SLICs, against transient overvoltages.
Positive overvoltages are clamped by 2 diodes.
Negative surges are suppressed by 2 thyristors,
their breakdown voltage being referenced to -VBAT
through the gate.
These components present a very low gate
triggering current (IGT) in order to reduce the
current consumption on printed circuit board
during the firing phase.
Benefits
TRISILs™ are not subject to ageing and provide a
fail safe mode in short circuit for a better level of
protection. Trisils are used to ensure equipment
meets various standards such as UL60950,
IEC950 / CSA C22.2, UL1459 and FCC part 68.
Trisils have UL94 V0 approved resin (Trisils are
UL497B approved [file: E136224]).

LCP1521S/LCP152DEE
Technical information
imposed by the various country standards. Taking into account this fact the actual lightning
surge current flowing through the LCP is equal to:
I surge = V surge / (Rg + Rs)
With:
V surge = peak surge voltage imposed by the standard.
Rg = series resistor of the surge generator
Rs = series resistor of the line card (e.g. PTC)
e.g. For a line card with 30 of series resistors which has to be qualified under GR1089
Core 1000V 10/1000 µs surge, the actual current through the LCP152 is equal to:
I surge = 1000 / (10 + 30) = 25 A
The LCP152 is particularly optimized for the new telecom applications such as the fiber in
the loop, the WLL, the remote central office. In this case, the operating voltages are smaller
than in the classical system. This makes the high voltage SLICs particularly suitable.
The schematics of Figure 7. give the most frequent topology used for these applications.
