P0721SCLRP Datasheet Sidactor Protection Thyristors

Manufacturer: Littelfuse

Overview: SIDACtor® Protection Thyristors SLIC Protection Fixed Voltage Series - DO-214 Agency Approvals Agency Agency File Number E133083 Pinout Designation Indicates cathode Schematic Symbol (T/R).

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

Fixed Voltage Series DO-214 are uni-directional SIDACtor® devices designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients.

The series provides single line protection using a fixed voltage switching device for negative surges.

All positive surges are routed through an internal diode to a ground reference.
