STMicroelectronics in production with new power MOSFETs

June 4, 2011
Driving up vehicle electrical efficiency

STMicroelectronics (ST), a global leader serving customers across the spectrum of electronics applications and a leader in semiconductors for automotive systems, has extended its range of STripFET VI DeepGATE power MOSFETs with the introduction of nine new automotive-grade devices that will deliver energy efficiency, size and cost benefits to cars in the near future.

Energy-efficient electrical systems are increasingly important to car makers. These systems manage equipment from window winders, wipers and heater blowers to engine controllers, starter-alternators and energy recovery systems.

Hybrid and electric vehicles, especially, need effective energy management for maximum traveling range.

ST's new power MOSFETs will minimize the energy normally lost in electrical drives and controls, leading to greater efficiency, while simultaneously reducing heat generation, allowing smaller, more lightweight assemblies, said the company.

This new series of AEC-Q101-qualified 30V and 40V power devices uses ST's advanced STripFET VI DeepGATE technology to achieve extremely low conduction losses relative to their active chip size. They feature low on-resistance ranging from 3.0 milliohms up to 12.5 milliohms in industry-standard DPAK or D2PAK surface-mount power packages, taking up less board space.

This new range of power MOSFETs also includes both logic- and standard-level types.

To assure reliability and robustness for automotive-grade applications, all devices undergo 100% avalanche testing both at wafer level and as finished products to meet the conditions for AEC-Q101 qualification. The new devices will also increase the efficiency of power supplies and drives for a wide range of non-automotive equipment and applications.
