-20-V p-channel MOSFET features lowest on-resistance

The Si7655DN is the industry’s first –20-V p-channel MOSFET in a 3.3 x 3.3-mm package to offer on-resistance of 4.8 mΩ max at a 4.5-V gate drive. It is the first device to be released in a new version of the PowerPAK 1212 package, which enables lower-R_DS(on) devices while providing a 28% slimmer nominal profile of 0.75 mm and maintaining the same PCB land pattern.

Applications for the p-channel MOSFET include load switching and hot swapping in industrial systems; adapter, battery, and load switches in charger circuits; and power management for smartphones, tablet PCs, and other mobile computing devices. The device is also used for redundancy switch, ORing, and supervisory applications in fixed telecom, cell phone base station, and server/computer systems. Prices start at $0.28 each in 100,000-piece quantities.
