2.9 mΩ Rds(on) and AEC‑Q101 Qualification in a Thermally Efficient DFN5060 Package
MCC introduces the MCAC2D9N04YHQ, a 40 V single N‑Channel MOSFET purpose-built for designers who need to switch high currents in minimal board space while maintaining high efficiency and safe operating temperatures in 12 V and 24 V systems. Using advanced split-gate trench technology, this device achieves an ultra-low 2.9 mΩ Rds(on) in a compact DFN5060 (5.0 mm × 6.0 mm) package, cutting conduction and switching losses and enabling high power density in space-constrained layouts.
AEC-Q101 automotive qualification and a robust 40 V VDS rating provide reliable operation under voltage spikes and harsh electrical conditions, making it well-suited for EV body electronics, DC-DC converters, battery management systems, energy storage, and motor control. A low 1.4 °C/W junction-to-case thermal resistance improves heat transfer and supports high current operation without bulky thermal solutions, while RoHS and halogen-free compliance ensure the MCAC2D9N04YHQ fits seamlessly into environmentally responsible, regulation-ready designs.
