Low-voltage power MOSFETs based on charge-compensation using a field-plate offer a significant reduction of the area-specific on-resistance. Beside a further improvement of this key parameter, the new device generation takes an in-depth focus on the

Regarding the ongoing efforts to reduce CO2 emissions of internal combustion engines, the potential friction benefits of toothed-belt drives become more important. In the course of the present study — which has been carried out by FEV on behalf of

Over the years improved silicon technologies for low-voltage power MOSFETs have led to a very low on-resistance of the die which is now comparable or even lower than that of the device package. Modern SMD packages offer a significant reduction of the

The trend of the last years to reduce the thickness of modern Power Silicon Chips was suspected to reduce the thermal performance of the MOSFET. This article shows from thermal point of view what happens in a typical packaged Power Switch during a hi
