LCP154DJF

Programmable transient voltage suppressor for SLIC protection

Datasheet

Features

• Programmable transient suppressor

• Wide negative firing voltage range: V

175 V max.

• Low dynamic switching voltages: V

• Peak pulse current:

• 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,

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.
