Vishay Intertechnology, Inc.: Vishay Siliconix Releases New 20-V and 30-V P-Channel TrenchFET(R) Power MOSFETs With Industry's
MALVERN, PA--(Marketwire - December 17, 2008) - Vishay Intertechnology, Inc. (
Whereas the available competing devices with these voltage ratings in the SO-8 footprint offer on-resistance only down to 24 milliohms, the Si7633DP offers an ultra-low on-resistance of 3.3 milliohms at 10 V and 5.5 milliohms at 4.5 V. These values are 27 % lower at 10 V and 28 % lower at 4.5 V than the closest competing 30-V device and 28 % and 15 % lower, respectively, than the closest competing 25-V SO-8 device. The 30-V Si7135DP offers an on-resistance of 3.9 milliohms at 10 V and 6.2 milliohms at 4.5 V. These values are 13 % lower at 10 V and 19.5 % lower at 4.5 V than the closest competing device.

Packaged in the PowerPAK® SO-8, both MOSFETs allow for a 60 % higher maximum drain current and 75 % higher maximum power dissipation than devices in the SO-8 package.
The devices will be used as the adaptor switch and for load switching applications in notebook computers and industrial/general systems. Adaptor switches (switching between the adaptor/wall power and the battery power) are always on and drawing current. The lower on-resistance of the Si7135DP and Si7633DP translates into lower power consumption, saving power and prolonging battery life between charges.
Vishay has also released the Si4459ADY 30-V p-channel TrenchFET power MOSFET in the SO-8 package. The device offers an on-resistance of 5 milliohms at 10 V and 7.75 milliohms at 4.5 V. All devices released today are 100 % Rg- and UIS-tested and halogen-free.
Samples and production quantities of the new Si7135DP and Si7633DP TrenchFET power MOSFETs are available now, with lead times of 10 to 12 weeks for larger orders.
