Fairchild FDN340P Single P-Channel MOSFET Datasheet
The document describes the Fairchild Semiconductor FDN340P, a single P-Channel Logic Level PowerTrench MOSFET. It is designed to minimize on-state resistance while maintaining low gate charge for superior switching performance in portable electronics applications such as load switching and DC/DC conversion.
Key specifications include a drain-source voltage rating of -20V, a continuous drain current of -2A, and an on-resistance (Rds(on)) of 70 mΩ at Vgs = -4.5V. The device is housed in a SuperSOT-3 package with identical pin-out to the standard SOT-23 but offers 30% higher power handling capability.
