Vishay Introduces 30-V P-Channel TrenchFET Gen III Power MOSFET

May 02, 2010 by Jeff Shepard

Vishay Intertechnology, Inc. unveiled the first 30V p-channel TrenchFET® Gen III power MOSFET in the PowerPAK® 1212-8 package. The device features what the company says is the industry’s lowest on-resistance for a p-channel MOSFET with this voltage rating in the 3.3 by 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 24V 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 7mΩ at 10V and 11mΩ at 4.5 V. These values are 30 % lower at 10V and 39% lower at 4.5V than the previously leading 30V device in the 3.3 by 3.3mm footprint area.

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 % higher, respectively, than the SO-8) or the space savings provided by the PowerPAK 1212-8. With a compact 3.3 by 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 % 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 2010, with lead times of 16 weeks for larger orders. Pricing for U.S. delivery in 100,000-piece quantities starts at $0.30 per piece.
