LCDP1521SDual line programmable TVS for SLIC protection | Circuit Protection | 1 | Active | This device has been especially designed to protect 2 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. Separated gates allow the SLICs to be supplied by two different voltages. |

LCP1531Protection for single voltage SLICs | Thyristors | 1 | LTB | These devices are ideally suited to meet the protection requirement of VoIP SLICs located in next generation residential gateways. They can be used for protecting any ringing SLIC since they meet the protection standard requirements.
Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBATthrough the gate.
These components present a very low gate triggering current (IGT) to reduce the current consumption on printed circuit board during the firing phase. |
LCP154Programmable transient voltage suppressor for SLIC protection | Thyristors | 1 | Active | 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. |
LCP22Protection IC for ringing SLICs | Interface | 1 | LTB | The LCP22 has been developed to protect SLICs operating on both negative and positive battery supplies, as well as high voltage SLICs. It provides crowbar mode protection for both TIP and RING lines. The surge suppression is assumed for each wire by two thyristor structures, one dedicated to positive surges the second one for negative surges. Both positive and negative threshold levels are programmable by two gates.
LCP22 can be used to help equipment to meet various standards such as UL1950, IEC 60950 / CSAC22.2, UL1459 and TIA-968-A. LCP22 pinout and clearance is compatible with UL60950. A Trisil™ meets UL94 V0.
The LCP22 associated with Epcos PTC model B59173C1130A151 is compliant with ITU TK20/K21 (4 kV lightning and AC power fault tests). |
LCP3121RLProgrammable transient voltage suppressor for SLIC protection | Thyristors | 1 | Obsolete | This device has been especially designed to protect single and dual voltages SLICs against transient overvoltages.
Connecting gate to the right supply voltage leads to overvoltage protection.
Used with diode bridges, LCP3121RL protects several twisted pairs.
LCP3121RL can be used to help equipment to meet various standards such as UL1950, IEC 60950 / CSAC22.2, UL1459 and TIA-968-A (formerly FCC part68). |
