1N5821RL Description

Short technical summary and product information.

The 1N5821RL is a Schottky barrier rectifier diode manufactured by On Semiconductor (onsemi). It is designed for low-voltage, high-frequency rectification applications. The device offers a maximum DC blocking voltage of 30 V and an average rectified forward current of 3 A. Its forward voltage drop is a low 500 mV at 3 A, contributing to high efficiency and reduced power loss. The diode features fast recovery speed (≤ 500 ns) and can handle a non-repetitive peak surge current of 80 A. The junction operating temperature range is -65°C to 125°C. The component is supplied in a through-hole axial package (DO-201AA / DO-27) with a cathode polarity band. It is commonly used in free-wheeling diodes, polarity protection, and low-voltage power supplies.
