This fixed voltage, unidirectional, modified DO-214 SIDACtor thyristor series is designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients.

These components provide single port protection implementing voltage switching characteristics for negative polarity surges and a clamping diode for positive polarity surges. All positive surges are routed through internal diodes to a ground reference.


  • Low voltage overshoot
  • Low on-state voltage
  • Does not degrade surge capability after multiple surge events within limit
  • Fails short circuit when surged in excess of ratings
  • Integrated diodes for positive voltage surges
  • Single-port protection
  • 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)


  • TIA-968-A
  • TIA-968-BITU K.20/21
  • Enhanced Level*
  • ITU K.20/21 Basic Level
  • GR 1089 Inter-building*
  • GR 1089 Intra-building
  • IEC 61000-4-5 2nd edition
  • YD/T 1082
  • YD/T 993
  • YD/T 950
