Shielded gate trench MOSFETs in TO-leadless packaging target autos

Available now from Digi-Key, Fairchild Semiconductor's innovative TO-LL devices offer an extremely low package resistance, a particularly small footprint, and allows for exceptionally favourable EMI behaviour. This technology is now offered in a range of voltage classes specifically designed and qualified for automotive applications. The combination of Fairchild's latest PowerTrench shielded gate trench technology with the TO-LL package delivers leadless MOSFET products with extremely low RDS(on) ranges. Both the superior silicon technology, as well as the package design, result in excellent switching and EMI performance, which is particularly beneficial for switching and PWM controlled applications in particular and has been verified by early customers of the devices. At the same time, the technology simplifies design, avoids additional passive components, and overall enables electronic manufacturers to better serve the markets for high-current applications. Compared to other discrete packages, the number of parallel MOSFETs needed in high-current applications can be significantly reduced, if not eliminated, leading to overall lower system costs, says the company.
