FemtoFET™ N-channel & P-channel MOSFETs

N-channel & P-channel MOSFETs

FemtoFET™ N-channel and P-channel MOSFETs are the smallest, low on-resistance power MOSFETs available in the marketplace today. FemtoFET MOSFETs are in a land grid array (LGA) package, which is a silicon chip scale package with metal pads instead of solder balls. They are ideal for mobile handsets, tablets, and any other application where saving board space and extending battery life are required.
