LCP154DJF

Programmable transient voltage suppressor for SLIC protection

Datasheet

production data

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.

• 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_H= 150 mA min.

Benefits

7LS

5LQJ

• 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]).

TM: Trisil is a trademark of STMicroelectronics
