Features
• Programmable transient suppressor
• Wide negative firing voltage range: V
Gn
= -
175 V max.
• Low dynamic switching voltages: V
FP
and V
DGL
• Low gate triggering current: I
GT
= 5 mA max.
• Peak pulse current:
–I
PP
= 100 A (10/1000 µs)
–I
PP
= 150 A (5/310 µs)
–I
PP
= 500 A (2/10 µs)
• Holding current: I

Benefits
• Trisil™ is not subject to ageing and provides 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,
IEC 60950 / CSA C22.2, UL1459, TIA-968-A
(formerly FCC part 68)
• Trisils have UL94 V0 approved resin (Trisils
are UL497B approved [file: E136224]).
Description
This device has 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 -V
BAT
through the gate.
LCP154DJF is specified to comply with
ITU-T K20/21/45 and GR1089-Core when
associated with Cooper Bussmann Telecom
Circuit Protector fuse TCP 1.25 A.
LCP154DJF is packaged in a PowerFLAT™ 5x6
to meet IEC/UL 60950 clearance requirements.
