The Si7625DN is the first 30 V p-channel TrenchFET® Gen III power MOSFET in the PowerPAK® 1212-8 package. The device features the industry's lowest on-resistance for a p-channel MOSFET with this voltage rating in the 3.3 mm by 3.3 mm footprint area. The new device will be used for adaptor, load, and battery switches in notebook computers, netbooks, and industrial/general systems. Adaptor switches (switching between the adaptor/wall power and the battery power) are usually on and drawing current. The lower on-resistance of the Si7625DN translates into lower power consumption, saving power and prolonging battery life between charges, while also reducing heat to enable a smaller PCB pad area. For load switches up to 24 V and hot-swap applications in industrial/general systems, the MOSFET's low on-resistance also results in lower voltage drops. The Si7625DN offers ultra-low on-resistance of 7 mΩ at 10 V and 11 mΩ at 4.5 V. These values are 30 % lower at 10 V and 39 % lower at 4.5 V than the previously leading 30 V device in the 3.3 mm by 3.3 mm footprint area.
