Bidirectional Transient Surge
Features
Suppressors (TO-202 Surgector)
• Clamping Voltage . . . . . . . . . . . . . . . . . . . . . 230V or 270V
These surgector devices are designed to protect
telecommunication equipment, data links, alarm systems,
power supplies and other sensitive electrical circuits from
• Rated for Peak Transient Surge Current
• High Minimum Holding Current
damage by switching transients, lightning strikes, load
• Low On-State Voltage
changes, commutation spikes and line crosses.
Bidirectional surgector devices are constructed with a
thyristor whose gate region contains a special diffused
msection which acts as a zener diode. This zener diode
section permits anode voltage turn on of the structure.
oInitial clamping by the zener diode section, and fast turn on
.cby the thyristor, provide excellent voltage limiting even on
very fast rise time transients. The thyristor also features high
holding current, which allows the surgector to recover to its
Uhigh impedance off state after a transient.
t4All these devices are supplied in a 2 lead, modified TO-202
package.
