Overvoltage / Suppression Protection

Surgector

™

Transient Voltage Suppressors

SGT (TO-202) Series

Features

Bidirectional Surge Suppressors:

(SGT 23B13, SGT 27B13, SGT 27B27)

•

Constructed with a thyristor whose gate

contains a special diffused section

which acts as a zener diode

Zener diode section permits anode

voltage turn on of the structure

Packaging: Modified TO-202

•

Unidirectional Surge Suppressors:

(SGT 03U13, SGT 06U13, SGT 23U13)

•

Offers unidirectional clamping action

Designed to protect telecommunications

equipment, data links, and other

sensitive electrical circuits from damage

by transients, lightning strikes, load

changes, and power line crosses

Packaging: Modified TO-202

•

Gate Controlled Unidirectional Surge

Suppressors: (SGT 27S10, SGT 27S23)

•

Fast turn-on, high holding

current thyristors

Provides excellent voltage limiting,

even on very fast rise time transients,

when coupled with a user supplied

voltage level detector

High holding current allows for

return to a high impedance off state

after a transient

Packaging: Modified TO-202
