1N5819 Description

Short technical summary and product information.

The 1N5819 is a Schottky barrier rectifier diode rated for 40V peak repetitive reverse voltage and 1A average forward rectified current. It offers a low forward voltage of 550 mV at 1A, reducing power loss in low-voltage, high-frequency circuits.

 

This diode is designed for output rectification, freewheeling, and polarity protection applications. It is housed in a DO-41 (DO-204AL) axial-lead through-hole package with a weight of 0.4 g and supports soldering at 260°C for 10 seconds.

 

The 1N5819 is part of the 1N581x series and is ESD rated (HBM 3B, MM C). It has a maximum junction temperature of 150°C and a thermal resistance of 80°C/W junction-to-ambient.
