Silicon Protection Circuits

Surface Mount Surgector^TMTransient Voltage Suppressors

Surgector Thyristors For Telecom Protection

Designed to suppress lightning and other transients, Surgector suppressors

are primarily intended for operation on the telephone line “tip and ring”

environment in order to protect telecommunications CPE and COE

products in conjunction with the Littelfuse 461 series Telecom Nano^2®fuse.

These devices provide secondary protection for telecommunication

equipment such as telephone, MODEM, line card and other devices

subject to damage from transient over voltage events. Surgectors can be an

integral part of a Telephone Line Protector Unit, meeting AC Power Cross

criteria when used in association with properly selected resistor/ PTC/ fuse

combinations such as the Littelfuse 461 series fuse. Littelfuse Surface

Mount Surgectors are manufactured using a silicon thyristor technology,

offering bidirectional voltage clamping for transients of either polarity

from a single chip.

Features

The Surgector devices described in this data sheet are manufactured

with the DO-214AA low profile case style and are second source

equivalent parts to industry “SIDAC” types. Surface Mount Surgector

Suppressors are supplied in embossed carrier tape on 330mm

(13in) reels.
