DESCRIPTION
This Power MOSFET is t he second generation of
STMicroelectronics unique “STripFET™” technolo­gy. The resulting transistor shows extremely low on­resistance and minimal gate charge. The new Pow­erFLAT™ package allows a significant reduction in board space without compromising performance.
