STMICROELECTRONICS STPS140A High Current Schottky Rectifier

The Schottky rectifier STPS140A is a compact, surface-mount power diode designed for high-frequency switching applications such as switched-mode power supplies, inverters, free-wheeling, and polarity protection. Featuring a low forward voltage drop of 0.5V, it offers very low conduction and switching losses, with a repetitive peak reverse voltage of 40V. Packaged in SMA form with JEDEC DO-214AC standards, it supports high current surges up to 60A and has avalanche capability, making it ideal for efficient, high-speed power rectification in modern electronic systems.
