1N5819G Description

Short technical summary and product information.

The 1N5819G is a Schottky barrier rectifier from onsemi designed for low-voltage, high-frequency applications. It offers a peak repetitive reverse voltage of 40V and an average rectified forward current of 1A. The forward voltage is typically 600mV at 1A, enabling low power loss and high efficiency.

 

This device employs Schottky Barrier technology with chrome barrier metal and epitaxial construction, resulting in low stored charge and majority carrier conduction. It is suitable for use as a rectifier in inverters, freewheeling diodes, and polarity protection circuits.

 

The 1N5819G is housed in an axial-lead DO-204AL (DO-41) package and is through-hole mountable. It is Pb-Free and RoHS compliant, with an operating temperature range of -65°C to 125°C.
