Silicon Protection Circuits  
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 SIDACtypes. Surface Mount Surgector  
Suppressors are supplied in embossed carrier tape on 330mm  
(13in) reels.  
Rated for Telecom Industry Transient Surge Levels:  
- Telcordia (Bellcore) GR-1089  
- ITU CCITT K.20/.21  
- FCC PART 68  
- UL 60950
