The SL1003 series has been especially developed for Broadband equipment. Special design features provide high levels of protection against fast rising transients in 100V/µs to 1kV/µs range usually caused by lightning disturbances.
These devices have Ultra low capacitance 1.5pF and present insignificant signal losses up to 1.5GHz. These devices are extremely robust and are able to divert a 5000A pulse without destruction. For AC Power Cross of long duration, overcurrent protection is recommended.

  • Low insertion loss
  • Surface mountable
  • 5kA surge capability tested with 8/20µS pulse as defined by IEC 61000-4-5
  • GHz working frequency.
  • Excellent response to fast rising transients.
  • Can be used to meet Telcordia GR1089 without series resistance
  • 10/700µs 6kV capability, as per ITU-T k.21, enhanced test level
  • 2000A 2/10µS surge rating
  • RoHS compliant


  • Broadband equipment.
  • ADSL equipment.
  • XDSL equipment.
  • Satellite and CATV equipment.
  • General telecom equipment.
