Philips MOSFET offers low on resistance

Royal Philips Electronics has developed what it claims as the world's first sub one milliohm MOSFET.

Demonstrating a reduction of approximately 40 percent in the on state resistance for MOSFETs compared to conventionally packaged products, the product reaches low levels of on resistance to enable designers to better manage power distribution, reduce board space and improve electrical efficiency within their systems.

The low on resistance was realized primarily due to the use of copper clip technology. With copper clips, instead of connecting to a single point, the entire surface of the chip is connected. Offered in a TO220-type package, the device is suitable for applications where power loss and heat dissipation are critical, such as computer mother boards.
