1N5819W / B5819W SOD123 (1206) 1A 40V Schottky Diode – Fast & Efficient Rectifier

Product Description:

The 1N5819W / B5819W Schottky Diode in the SOD123 (1206) SMD package is a high-efficiency, fast-switching rectifier designed for low-voltage, high-current applications. With a 1A forward current rating and 40V reverse voltage, this diode is widely used in DC–DC converters, battery-powered devices, power supply modules, LED drivers, and polarity protection circuits.

Schottky barrier technology ensures very low forward voltage drop, significantly reducing power loss and heat generation—making it ideal for high-efficiency and compact electronic designs. The durable SOD123 (1206) package provides excellent thermal and electrical performance for surface-mount applications.
