SIDACtor Devices, Fixed Voltage for SLIC Overvoltage Protection

The Pxxx1DF-1 and Pxxx1DF-1E Series from Littelfuse protects SLICs from damaging overvoltage transients


The Pxxx1DF-1 and Pxxx1DF-1E Series Fixed Voltage Protection SIDACtors® from Littelfuse enhance the reliability of telecom equipment by protecting sensitive SLICs (Subscriber Line Interface Circuits) from damaging overvoltage caused by lightning and AC power faults. Unlike programmable solutions, the new series do not require a large and costly gate capacitor, and offer a complete single-port overvoltage protection with a single compact device. The series each use a fixed-voltage switching device to protect against both positive and negative induced surge events without the need of additional external components.

Features
  • Integrated diode for positive surges
  • Fails short circuit when surged in excess of ratings
  • Does not degrade with use
  • Low overshoot voltage during surge events
  • Single port (both tip & ring) protection in a single package
  • Pin-to-pin footprint compatible to programmable SO-8 package SLIC protectors
  • Unlike programmable solutions, both series do not require a bulky gate capacitors
