Tyco Electronics / Raychem Circuit Protection Polyswitch TSM600-250

TE Connectivity announces the introduction of a new Raychem Circuit Protection Polyswitch TSM600-250 over-current protection device for DSL and other telecommunications network equipment applications. The small-footprint, low-resistance, surface-mount device provides tandem resettable over-current circuit protection for use in high-density multi-port line cards and other telecommunications network equipment. The TSM600-250 device incorporates two matched, low-resistance PPTC (polymeric positive temperature coefficient) components into a single device yielding balanced protection on tip-and-ring lines with minimal attenuation of data transmission.

  • SMT for factor
  • Maximum interrupt fault rating of 600VAC
  • Lightning surge capability of 1kV, 100A, 10/1000µsec
  • Low resistance
  • Hold current of 250mA
  • Two resistance matched PPTC protection components per package
  • Small footprint


  • xDSL and ADSL linecards
  • T1/E1 systems
  • Twisted pair telecom ports requiring Telcordia GR-1089 compliance
  • Battery powered devices
  • DC / DC converters in distributed power systems
  • DC / DC convert for Field Programmable Gate Array (FPGA)
