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 -VBAT 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.

Features
■ Programmable transient suppressor
■ Wide negative firing voltage range: VGn = - 175 V max.
■ Low dynamic switching voltages: VFP and VDGL
■ Low gate triggering current: IGT = 5 mA max.
■ Peak pulse current: – IPP = 100 A (10/1000 µs) – IPP = 150 A (5/310 µs) – IPP = 500 A (2/10 µs)
■ Holding current: IH = 150 mA min. 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]).
