The STU417S manufactured by VBsemi Elec is a P-Channel Metal-Oxide Semiconductor Field-Effect Transistor (MOSFET) with a maximum voltage rating of 30V, maximum current of 40A, and on-resistance (Rds(on)) of 18mO@10V, 40A. It comes in an industry standard TO-252 package, and is RoHS compliant. This MOSFET is typically used for heavy-duty applications where the power delivery needs to be managed, such as controlling a motor or a lighting system. It is also suitable for various other purposes, such as battery charging, voltage regulation, power switching, and driving loads.
