The new SEP (SIDACtor Ethernet/PoE Protector) 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
