The new SEPxxxxQ38 series has a surge rating compatible with GR1089 Inter-building and ITU K.20/21 Enhanced protection requirements.

Targeted for high-speed applications such as 10BaseT, 100BaseT, and 1000BaseT, the SEP series maintains signal quality while providing robust protection for Ethernet and PoE applications.

This latest silicon design innovation results in a capacitive loading characteristic that is constant with respect to the voltage across the device. This reduces distortion caused by typical solid-state protection solutions.

Offered in a surface-mount, QFN package, the SEP provides small package size without sacrificing power and surge handling capabilities.

Features & Benefits:

  • Compatible with 1000Base - T
  • Balanced over-voltage protection
  • Low distortion
  • Low insertion loss
  • Low profile
  • Small SO-8 footprint
  • Fails short circuit when surged in excess of ratings

Applicable Global Standards:

TIA-968-A, TIA-968-B, ITU K.20/21 Enhanced Level, ITU K.20/21 Basic LeveL, IEC 61000-4-5 2nd edition, IEC 61000-4-5 2nd edition, GR 1089 Intra-building, YD/T 1082, YD/T 993, YD/T 950, Class 4/5 compliance of IEC 61000--4-5
