SIDACtor® SLIC Protection SMD Thyristors


Littelfuse introduces fixed voltage single port SLIC protection


The Littelfuse Pxxx1DF-1 and Pxxx1DF-1E series fixed voltage protection SIDACtor® devices 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, this new series does not require large and costly gate capacitors, and it offers complete single-port overvoltage protection in a single compact device. The series uses a fixed-voltage switching device to protect against both positive and negative induced surge events without the need of additional external components.
