SILICONIX DEBUTS SEVEN NEW POWER MOSFETS IN D2PAK PACKAGE.

Seven new power MOSFETs in a thermally enhanced D2PAK package, which enables a record-low level of thermal resistance and is capable of handling 29% more current than the conventional D2PAK, have been introduced by Siliconix incorporated (Nasdaq:SILI), an 80.4%-owned subsidiary of Vishay Intertechnology Inc. (NYSE:VSH).

The new n-channel 40- to 200-V TrenchFETs are designed for use in automotive and communications applications, including motor control, ABS, electric power steering, and 42-V Boardnet applications in cars, and for primary-side switching in the isolated dc-to-dc converters used in servers, routers, and networks.

Vishay's new thermally enhanced D2PAK incorporates a proprietary leadframe design that allows devices in the "SUM" series to offer the industry's lowest thermal resistance for this package type, depending on the die-size used.

Compared with conventional D2PAK devices, the new SUM series offers up to 29% higher maximum current of 100 A, 75% higher power dissipation of up to 437.5 W, and on-resistance as low as 2.3 milliohms. Thermal resistance is as low as 0.4 degrees Centigrade per watt -- 33% lower than in standard D2PAK devices.

As a result, the devices can handle higher current and more power, or run cooler while handling the same amount of current and power.

Higher current-handling capability and lower on-resistance values allow designers to save board space and lower production costs because it's possible to run fewer MOSFETs in parallel to reach the required current level and power load for a given application. By eliminating one or more MOSFETs, designers can reduce component, assembly, and testing costs.

In addition to superior current-handling and power-dissipation capabilities, select D2PAK TrenchFETs in the SUM series feature a maximum junction temperature as high as 200 degrees Centigrade, an improvement of as much as 14% in the standard D2PAK footprint.

Samples and production quantities of the SUM110N04-02L, SUM110N04-03, SUM110N06-04L, SUM110N08-05, SUM110N10-09, SUM85N15-19, and SUM65N20-30 are available now, with lead times of 10 to 12 weeks for larger orders.
