1N5821RLG Description

Short technical summary and product information.

The 1N5821RLG is a 30V, 3A Schottky barrier rectifier manufactured by ON Semiconductor. This diode utilizes Schottky barrier technology to provide extremely low forward voltage drop (500 mV at 3 A) and fast switching with majority carrier conduction, making it suitable for low-voltage, high-frequency applications.

 

The device is rated for a DC blocking voltage of 30 V and an average rectified current of 3 A. It is housed in an axial lead, epoxy molded DO-201AD case (also referenced as DO-201AA or DO-27). The junction operating temperature range is -65°C to +125°C, with a thermal resistance of 28 °C/W junction-to-ambient. The cathode is indicated by a polarity band on the body.

 

Common uses include rectification in low-voltage power supplies, freewheeling diodes in switching converters, and polarity protection circuits. The part is also available with a "RL" suffix for tape and reel packaging (1500 per reel).
