## Compact DFN5060 Package for High-Current, Space-Constrained Power Designs
MCC introduces a 40V N-channel MOSFET ([MCAC2D6N04Y](https://www.mccsemi.com/products/mosfets/power-mosfets/mcac2d6n04y)) in a compact DFN5060 package, engineered for designs where efficiency, power density, and board space are equally critical. Featuring an ultra-low RDS(on) of 2.6 mΩ (VGS = 10 V) and a high 166 A continuous drain current rating, this device minimizes conduction losses and heat generation, allowing designers to deliver more power in a smaller footprint while easing thermal design. Its combination of very low on-resistance, fast and efficient switching, and small package size makes it an ideal solution for battery protection circuits, compact DC-DC converters, motor drive stages, and other space-constrained power systems.
With its Split Gate Trench structure delivering low gate charge (Qg = 38.3 nC) and fast switching, the MCAC2D6N04Y-TP is well suited for high-frequency power stages where switching losses and EMI must be tightly controlled. The device’s 175 °C maximum junction temperature provides solid headroom for demanding load conditions, reducing the need for heavy heatsinking and lowering overall thermal overhead.

##### Features & Benefits:
- Ultra-low RDS(on) of 2.6 mΩ (max) at VGS =10V, minimizing conduction losses to extend battery life and boost overall system efficiency
- Split Gate Trench technology optimized for low gate charge (Qg = 38.3 nC) and high switching speed, enabling efficient
- High continuous drain current (ID) rating of 166 A, delivering robust power handling in demanding power designs
- High maximum junction temperature of 175 °C, improving device ruggedness and relaxing cooling and thermal management requirements
- Compact DFN5060 package (5.0 mm × 6.0 mm), reducing board space while supporting high power density layouts
- RoHS compliant and halogen-free, meeting global environmental and regulatory standards
