Vishay Intertechnology, Inc.: Vishay Siliconix Releases New 20-V P-Channel TrenchFET(R) Gen III Power MOSFET With Industry's Lo
MALVERN, PA--(Marketwire - May 11, 2009) - Vishay Intertechnology, Inc. (
The new Si7615DN offers an ultra-low on-resistance of 3.9 milliohms at 10 V, 5.5 milliohms at 4.5 V, and 9.8 milliohms at 2.5 V. The low on-resistance of the TrenchFET Gen III MOSFET translates into lower conduction losses, allowing the device to perform switching tasks with less power than any previous p-channel power MOSFET on the market.
The Si7615DN will be used as the adaptor switch and for load switching applications in notebook computers, netbooks, and industrial/general systems. Adaptor switches (switching between the adaptor/wall power or the battery power) are always on and drawing current. The lower on-resistance of the Si7615DN translates into lower power consumption, saving power and prolonging battery life between charges.
The Si7615DN joins Vishay's recently released 20-V p-channel TrenchFET Gen III Si7137DP 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 (60 % and 75 % higher, respectively, than the SO-8) or the space savings provided by the PowerPAK 1212-8.
The Si7615DN frees designers from having to rely on 30-V power MOSFETs, which until recently were the only p-channel devices available within this very low on-resistance range. Among competing 30-V devices, the lowest available p-channel on-resistance with the area of the PowerPAK 1212-8 is 14.4 and 27 milliohms at gate drives of 10 V and 4.5 V, respectively.
The device is 100 % Rg-tested and halogen-free in accordance with IEC 61249-2-21.
Samples and production quantities of the new Si7615DN TrenchFET power MOSFET are available now, with lead times of 10 to 12 weeks for larger orders.
