Overview
The FDN304P is a P-Channel MOSFET from onsemi, optimized for low-voltage applications using the advanced POWERTRENCH process. This device is particularly suited for battery power management, load switching, and battery protection. It features a SUPERSOT-23 package, which offers 30% higher power handling capability compared to the standard SOT-23 package in the same footprint. The FDN304P is Pb-free, halogen-free, and RoHS compliant, making it an environmentally friendly choice.
