SIDACtor® Data Book and Design Guide

Product Description

SIDACtor components are solid state crowbar devices designed to protect telecom

equipment during hazardous transient conditions. Capitalizing on the latest in thyristor

advancements, Teccor makes SIDACtor devices with a patented ion implant technology.

This technology ensures effective protection within nanoseconds, up to 5000 A surge

current ratings, and simple solutions for regulatory requirements such as GR 1089,

TIA-968 (formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950.

Operation

In the standby mode, SIDACtor devices exhibit a high off-state impedance, eliminating

excessive leakage currents and appearing transparent to the circuits they protect. Upon

application of a voltage exceeding the switching voltage (VS), SIDACtor devices crowbar

and simulate a short circuit condition until the current flowing through the device is either

interrupted or drops below the SIDACtor device’s holding current (IH). Once this occurs,

SIDACtor devices reset and return to their high off-state impedance.

V-I Characteristics

Advantages

Compared to surge suppression using other technologies, SIDACtor devices offer absolute

surge protection regardless of the surge current available and the rate of applied voltage

(dv/dt). SIDACtor devices:

• Cannot be damaged by voltage

• Eliminate hysteresis and heat dissipation typically found with clamping devices

• Eliminate voltage overshoot caused by fast-rising transients

• Are non-degenerative

• Will not fatigue

• Have low capacitance, making them ideal for high-speed transmission equipment
