A0609CA2LRP is an LCAS protector that does not require an external voltage reference. It specifically provides protection for a balanced ringing system with a ringing voltage range of +54 volts and -78 volts.

This three pin modified DO-214AA solution provides a smaller footprint and lower component count than the typical dual polarity programmable SLIC protector. This new overvoltage protector is applicable for WLL ( Wireless local loops), VoIP (Voice over IP) and regenerated POTS (Plain Old Telephone Systems) applications.


  • Modified DO-214AA
  • Solid-State transient protection
  • Switching speeds of nanoseconds
  • Fixed voltage asymmetrical design
  • Robust surge rating
  • Lower component count solution
  • Eliminates the need for large, bulky capacitors and blocking diodes required by traditional programmable solutions
  • Halogen free and RoHS compliant
  • 2nd level interconnect is Pb-free per IPC/ JEDEC J-STD-609A.01
