The SuperSOT-8 family of P-Channel Logic Level MOSFETs have been designed to provide a low profile, small footprint alternative to industry standard SO-8 little foot type product. These P-Channel Logic Level MOSFETs are produced using Fairchild Semiconductor's advanced PowerTrench process that has been tailored to minimize the on-state resistance and yet maintain superior switching performance.
These devices are well suited for portable electronics applications: load switching and power management, battery charging circuits, and DC/DC conversion.
