MCG6D9N04YHQ-TP-VB Product details

Product introduction:

You are designing a high-power-density DC-DC converter with tight board space, yet you need to continuously handle over 30A of high current. Traditional MOSFETs either have large packages or suffer from high conduction losses. The VBsemi MCG6D9N04YHQ-TP-VB is designed to solve this pain point—it integrates a 40V drain-source voltage, 40A current capability, and an ultra-low on-resistance of 4.5mΩ into a compact DFN8(3X3) package, enabling high-current power designs to balance efficiency and miniaturization.
