Surge Suppressors (TO-202 Surgector)
Surgector transient surge protectors are designed to protect
telecommunication equipment, data links, alarm systems,
power supplies, and other sensitive electrical circuits from
damage that could be caused by switching transients,
lightning strikes, load changes, commutation spikes, and line
crosses.
These devices are fast turn-on, high holding current
thyristors. When coupled with a user supplied voltage level
detector, they provide excellent voltage limiting even on very
fast rise time transients. The high holding current allows this
surgector to return 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.
