1N5817 Description

Short technical summary and product information.

The 1N5817 is a Schottky barrier rectifier diode designed for low-voltage, high-frequency applications. It offers a peak repetitive reverse voltage rating of 20V and an average rectified forward current of 1A. The forward voltage is typically 450 mV at 1A forward current, enabling high efficiency with low power loss.

 

This component is well-suited for use as a rectifier in switching power supplies, freewheeling diodes, and polarity protection circuits. Its majority carrier conduction ensures fast switching with minimal stored charge, making it ideal for high-frequency inverters. The device is rated for an operating junction temperature range of -65°C to +125°C, with a peak junction temperature of 150°C.

 

The 1N5817 is housed in a through-hole DO-41 (DO-204AL) package with axial leads, allowing for easy mounting on printed circuit boards. It is lead-free and manufactured with epoxy molding. The device meets ESD ratings of >8000V (Human Body Model) and >400V (Machine Model).
