Overview
The STPS20120CFP is a dual diode Schottky rectifier produced by STMicroelectronics. This component is designed for high-frequency switched-mode power supplies and is available in various packages, including DPAK, TO-220AB, TO-220AB narrow leads, and I²PAK. It is particularly suited for applications in notebook and LCD adaptors, as well as desktop SMPS, where it provides a reliable margin between the applied voltages and the diode's voltage capability.
