axial Schottky barrier rectifier FUXINSEMI SR3100 with low forward voltage drop and high surge capability
Product Overview
The SR320 THRU SR3200 series are 3.0A Axial Schottky Barrier Rectifiers designed for through-hole mounting. These devices offer low power loss, high efficiency, and high current capability with ultra-high-speed switching. Featuring a silicon epitaxial planar chip with a metal silicon junction, they provide low forward voltage drop and high surge capability. A guardring is integrated for overvoltage protection. These rectifiers are suitable for applications requiring reliable and efficient rectification from 20V to 200V. Lead-free parts meet environmental standards of MIL-STD-19500/228.
