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 (V_S), 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 (I_H). Once this occurs,

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

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
