Pxxx2SxL Series Two-Chip SIDACtor® DO-214AA are very low capacitance SIDACtor® Protection thyristors designed to protect broadband ICT equipment such as VoIP, xDSL modems and DSLAMs from damaging overvoltage transients. This series provides a surface mount solution that enables equipment to comply with global regulatory standards, while limiting the impact to broadband signals.

Features & Benefits:

  • Low voltage overshoot
  • Low on-state voltage
  • Does not degrade surge capability after multiple surge events within limit
  • Low distortion
  • Fails short circuit when surged in excess of ratings
  • RoHS Compliant and Halogen Free
  • Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD 609A.01)
  • Recognized to UL 497B as an Isolated Loop Circuit Protector

Applicable Global Standards:

  • TIA/968-A/B
  • ITU K.20/21/45
  • IEC 61000-4-5 2nd edition
  • GR 1089 Intra-building
