Surge Suppressors Can Fend Off Up To 3 kA Surges

Designed to handle surge currents up to 3 kA, the SIDACtor series of TVS suppressors is made using a patented ion-implant technology that enables the devices to provide surge protection within nanoseconds. Transparent to the circuits they protect in standby mode, the suppressors exhibit a high off-state impedance to eliminate excessive leakage currents. When triggered by voltages in excess of the switching voltage, the devices simulate a short-circuit condition until the current falls below its holding value. Then the surge suppressors reset and return to a state of high off-state impedance. Typically placed behind a slow-blow fuse or other current limiters, the suppressors eliminate voltage overshoot caused by fast rising transients. The series has a V_DRM of from 6V to 320V, with its surge ratings extending from 50A for a 10 x 560 µs event to 500A for a 2 x 10 µs event. Operating temperatures range from 0°C to +150°C.
