onsemi NTMFSC0D9N04CL-01

NTMFSC0D9N04CL is a single N-channel MOSFET in a DFN8 5x6 package, designed for high-efficiency power switching in applications such as synchronous rectification and DC-DC conversion. It has a maximum drain-to-source voltage of 40 V and a continuous drain current of 313 A at TC = 25°C, with a typical on-resistance of 0.85 mΩ at 10 V and 1.3 mΩ at 4.5 V. The device supports a pulsed drain current of 900 A and has a maximum power dissipation of 167 W under steady-state conditions with a case temperature of 25°C. Thermal resistance from junction to case (bottom) is 0.9 °C/W, and junction-to-ambient thermal resistance is 39 °C/W on a 1 in² FR4 PCB with 1 oz Cu. The part is Pb-free, halogen-free, RoHS compliant, and has an operating junction and storage temperature range of -55°C to +175°C.
