This Product is Obsolete. For new Designs use the SIDACtor PxxxxS_ Series devices. 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 silicon thyristor technology, offering bi-directional voltage clamping for transients of either polarity from a single chip. 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.
