The Teccor SIDACtor is a solid state transient voltage protector designed for use in telephony, data, and some
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.
The SIDACtor will return to its high impedance state when the current is interrupted or falls below the minimum
holding current of the device.

Pulse Current rating. It should be noted that the SIDACtor will fail short if the device is subjected to a surge that
exceeds its rated Peak Pulse Current (IPP) or Peak One Cycle Surge Current (ITSM).
SIDACtors are available in breakdown voltages ranging from 30 to 540 volts and Peak Pulse Current ratings up
to 500 amps (2x10µS). Tape-and-reel packaging is available for the TO-92 and TO-220 packages along with
embossed carrier reel packing for the DO-214AA.
