The B5819W with Schottky Barrier Diodes (SBD) SOD-123 RoHS is a diode manufactured by Microdiode Electronics. It is a small surface-mount device composed of two diodes in a single package, allowing two-way protection from voltage surges. It has a reverse leakage current of less than 1µA at 25°C and a forward current of 800mA. The device has a Schottky barrier which allows efficient current flow, with a forward voltage of 0.3 V at 25°C. The diode has a high surge power rating, with a Peak Pulse Power of 250W at 8.3 ms and 150W at 10 ms. It also has a coefficient of temperature between - 40°C to + 125°C, allowing it to be used in a wider range of applications. The B5819W comes in a SOD-123 RoHS compliant package and is RoHS compliant. This device is suitable for use in a wide range of applications, including automotive, industrial, telecom, and consumer electronics.
