Littelfuse introduces the Surgector™ Series surface mount thyristor circuit protection device, specifically designed to protect telecom equipment. Surgectors protect circuits from transient voltages induced or coupled into telecommunications equipment due to lightning. In addition, these products protect any peripheral equipment connected to the telephone network, such as internet appliances, modems and fax machines. Surgectors comply with the requirements listed in UL 1950, Belcore 1089, CCITTK.20, FCC Part 68.

Littelfuse Surgectors are also designed to protect cable equipment such as set- top boxes and cable modems.The family of devices is packaged in a low-profile DO-214AA package that is small enough to fit into a PCMCIA modem. To support a wide range of designs the product is offered in nine different voltages — ranging from 64 to 350 volts. Furthermore, the device performance includes a sub-nanosecond turn on time in 50 A and 100 A current ratings.
