The BAS40-04-7-F is a Schottky Diode & Rectifier by Diodes Incorporated. It is a 40V, 350mW with a low forward voltage drop for higher efficiency and superior performance in many applications. It is constructed using a combination of surface-mount technology and traditional rectifier molding techniques and is packaged in the SOT-323 Small Outline Transistor (SOT-23) outline. It offers excellent protection in low-voltage power applications where fast switching, low power dissipation and high reliability are required. The low forward voltage drop of this part helps reduce power requirements and eliminate unwanted switching delays. It is ideal for DC-DC converters, automotive power control, voltage regulation and LED lighting applications.
