Vishay Intertechnology Inc. has introduced a 30V 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 3.3mm x 3.3mm footprint area.

The new Si7625DN 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 7m at 10V and 11m at 4.5V. These values are 30 percent lower at 10V and 39 percent lower at 4.5V than the previously leading 30V device in a small footprint.

The new MOSFET joins Vishay's previously released 30V p-channel TrenchFET Gen III Si7145DP in the PowerPAK SO-8 package. To meet the needs of individual applications, the p-channel TrenchFET Gen III packaging options offer designers a choice between the maximum drain current and power dissipation of the PowerPAK SO-8 (85 and 79 percent higher, respectively, than the SO-8) or the space savings provided by the PowerPAK 1212-8. With a compact 3.3mm x 3.3mm footprint, the device offers one-third the footprint area of the PowerPAK SO-8 or SO-8 type packages.

The MOSFET is 100 percent Rg- and UIS-tested, compliant to RoHS Directive 2002/95/EC, and halogen-free in accordance with IEC 61249-2-21.

Samples of the new Si7625DN TrenchFET power MOSFET are available now. Production quantities will be available in Q2, with lead times of 16 weeks for larger orders.
