1N5819RLG Description

Short technical summary and product information.

The 1N5819RLG is a Schottky barrier rectifier from ON Semiconductor designed for low-voltage, high-frequency applications. It features a peak repetitive reverse voltage of 40V and an average rectified forward current of 1A.

 

This device employs Schottky barrier technology with chrome barrier metal and oxide passivation, resulting in low forward voltage and minimal stored charge. The forward voltage is typically 600 mV at 1A, contributing to high efficiency and low power loss.

 

Packaged in a through-hole axial DO-204AL (DO-41) case, this diode is suitable for automated insertion and wave soldering. It is rated for operation over -65°C to 125°C and has a non-repetitive surge current capability of 25A.

 

Typical applications include polarity protection, freewheeling diodes, and output rectification in switch-mode power supplies. The part is lead-free (Pb-Free) and molded in epoxy.
