Key Features

ProTek's Thyristor Surge Suppression devices are designed to protect telecommunications equipment against lightning and transients induced by AC power lines. These devices are ideal for use in central office equipment, PBX, DSU, OCU, digital telephones, fax machines, modems and radio controlled equiment.

Thyristors are offered in a bidirectional configuration. The discrete surface mount package allows individual placement of the device on printed circuit boards or other locations where multiple component devices do not offer the versatile in board trace layout.

These devices provide protection in accordance with industry standard immunity requirements such as FCC Part 68, ANSI C62.41, UL 1459 and GR-1089-CORE. In addition, ProTek's Thyristors are designed to meet EFT immunity requirement IEC 61000-4-4 (40A, 5/50ns) and Surge (Power, Line to Ground and Line to Line) immunity requirement IEC 61000-4-5 (Levels vary depending upon product series).
