| ee Surge Unidirectionalh Transient Suppressors (TO-202 Surgector) [ /Title aS (SGT0 at 3U13, .D SGT06 w U13, w SGT23 U13) w /Subject (Unidirectional Transient Surge Suppressors (Surge ctor)) /Autho r () /Keywords (Surge ctor, TVS, Transient Suppression, 4U t om .c SGT03U13, SGT06U13, SGT23U13 July 1999 File Number Data Sheet Features * Clamping Voltages: 33V, 60V, or 230V * High Peak Transient Surge Current * Minimum Holding Current: 130mA * Low On-State Voltage * UL Recognized File #E135010 to STD 497B These surgector devices offer unidirectional clamping action and are designed to protect telecommunication equipment, data links, alarm systems, power supplies and other sensitive electrical circuits from damage by switching transients, lightning strikes, load changes, commutation spikes and power line crosses. These surgector devices are monolithic compound structures consisting of a thyristor whose gate region contains a special diffused section which acts as a zener diode. This zener diode section permits anode voltage turnon of the structure. Initial clamping by the zener diode section and fast turn-on by the thyristor, provide excellent voltage limiting even on very fast rise time transients. The thyristor also features very high holding current allowing the surgector to recover to its high impedance off state after a transient. The surgector device's normal off-state condition in the forward blocking mode is a high impedance, low leakage state that prevents loading of the line. These surgector types are supplied in the modified TO-202 package.
