General Information
The Teccor SIDACtor is a solid state transient voltage protector designed for use in telephony, data, and some AC applications. The SIDACtor is a bidirectional device that is normally connected to the high side of a circuit and a common. The SIDACtor remains in a high off-state impedance (leakage current <5µA) until it senses a voltage exceeding its voltage breakover (VBO). Upon sensing an overvoltage, the SIDACtor will clamp the voltage and transition through a positive or negative zener region until enough current is present to allow the device to crowbar into a low impedance state. The typical voltage drop across the device during full conduction is typically less than 5 volts.
