1N5822RL

1N5822RL Description

The 1N5822RL from STMicroelectronics is a high-performance Schottky barrier rectifier diode designed for fast switching and low forward voltage drop applications. With a 40V reverse voltage (Vr) and 3A average rectified current (Io), it is optimized for efficiency in power supply circuits, DC-DC converters, and reverse polarity protection systems. The diode features a fast recovery time of ≤500ns, making it ideal for high-frequency applications. Its Schottky technology ensures minimal power loss, while the 525mV maximum forward voltage (Vf) at 3A enhances energy efficiency. Packaged in a DO-201AD through-hole format and supplied in Tape & Reel (TR), it is suitable for automated assembly processes.
