LCP154DJF

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 -VBAT through the gate. 5LQJ *Q 1& 7LS 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. 3RZHU)/$7Œ[ LCP154DJF is packaged in a PowerFLAT™ 5x6 to meet IEC/UL 60950 clearance requirements.

Example of PCB layout based on LCP154DJF protection To line side To SLIC side >2 mm GND 100 nF GND Figure 4 shows the classical PCB layout used to optimize line protection. The 2 mm distance is used to comply with IEC/UL 60950 clearance requirements. The capacitor C is used to speed up the crowbar structure firing during the fast surge edges. This allows minimization of the dynamic breakover voltage at the SLIC Tip and Ring inputs during fast strikes. Note that this capacitor is generally present around the SLIC - Vbat pin. So to be efficient it has to be as close as possible from the LCP Gate pin and from the reference ground track (or plan). The schematics of Figure 5 give the topology used to protect all SLICs according to ITU-T K20/21/45 and GR1089-Core. Figure 5.
