1N5819 Description

Short technical summary and product information.

The 1N5819 is a Schottky barrier rectifier diode manufactured by Diotec Semiconductor, rated for a repetitive peak reverse voltage of 40V and an average rectified forward current of 1A. It comes in a through-hole DO-204AC (DO-15) package and is designed for use in low-voltage, high-frequency rectification circuits, freewheeling diodes, and polarity protection applications.

 

Specifications include a forward voltage of 0.9V at 3A, a peak forward surge current of 40A, and a leakage current of 1000µA at 40V. The junction temperature range is -50°C to 150°C, with a thermal resistance junction-to-ambient of 80°C/W and junction-to-lead of 15 K/W. The device is ESD rated with a human body model of >8000V.

 

The component has a net weight of approximately 0.4g, with corrosion-resistant and solderable terminals. Maximum lead soldering temperature is 260°C for 10 seconds. The package is UL 94 V-0 rated for flammability.
