STMICROELECTRONICS STPS140U High Frequency Schottky Rectifier

The power Schottky rectifier is a surface-mount device designed for high frequency switching and low voltage applications such as switched mode power supplies and inverters. Packaged in SMB form, it features very small conduction and switching losses, a low forward voltage drop, and avalanche capability. Suitable for polarity protection and freewheeling, this rectifier provides reliable performance in demanding electronic circuits, with a maximum junction temperature of 150°C, repetitive peak reverse voltage of 40V, and a maximum forward current of 1A, supported by thermal resistance ratings and electrical characteristics tailored for efficient power conversion.
