Power line protection: surge current > 24 A

Image

ST’s power-line overvoltage protection devices support applications such as satellite boxes (LNB), high power DC-DC converters, and telecom power rails.

They are designed to meet IEC 61000-4-5 and offer:

  • Surge current capability up to 500 A
  • Wide package offering, including multi-line high-power device packages
  • Devices optimized to support specific applications

The ITA series is optimized for industrial applications, the SLVU and PEP01 for Ethernet or PoE, and the STIEC45 series is for DC power rails.
