The BAT54S-E3-08 is a surface-mount, dual Schottky diode and rectifier manufactured by Vishay. It is designed for use in low voltage applications, such as portable electronic devices, and is rated for 200mA and 30V. It offers low forward voltage drop, fast switching, and excellent electrical performance. The diode is housed in a small low-profile SOD-323 package, allowing for efficient thermal management and space savings in applications where board space is at a premium. The diode also has a low forward voltage drop of 0.45V at 100mA. It is RoHS Compliant.
