Surface Mount SurgectorTM Transient 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 Nano2® 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.

1.78
Surface Mount Surgectors may be soldered with wave or reflow methods,
and are compatible with common industry time-temperature profiles that
include a preheat stage. When hand soldering, a 30W iron with a 1mm
tip is recommended. The temperature should not exceed 300oC or a
maximum 5 second duration.
