The MS-012 packaged Fixed Voltage Enhanced Single Port Series are SIDACtor® devices designed to protect sensitive SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients.

The series provides single port protection using a fixed voltage switching device for negative surges. Positive surges are routed though enhanced switching diodes to a ground reference. The series is also pin-to-pin compatible to industry standard programmable SO-8 SLIC protectors.

Features & Benefits:
  • Integrated fast switching diodes for positive voltage surges
  • Single port protection in one package
  • Low voltage overshoot
  • Low on-state voltage
  • Does not degrade with use
  • Fails short circuit when surged in excess of ratings
  • Pin-to-pin SO-8 compatible footprint

Applicable Global Standards:
  • TIA-968-A
  • ITU K.20/21 Enhanced Level
  • ITU K.20/21 Basic Level
  • GR 1089 Inter-building*
  • GR 1089 Intra-building*
  • IEC 61000-4-5
  • YD/T 1082
  • YD/T 993
  • YD/T 950
