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 -VBATthrough 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.
- 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.
