  • 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).

    Key Features

    • Programmable transient voltage suppressor compatible with:
      • single voltage SLICs
      • dual voltage SLICs
      • multi line SLICs
    • Firing voltage range: -100 V to +100 V
    • Peak pulse current:
      • IPP = 100 A (10/1000 µs)
      • IPP = 150 A (5/310 µs)
      • IPP = 250 A (2/10 µs)
    • Holding current: IH = 100 mA min.
