Procurement Notes
Verify the specific automotive grade certification and RoHS compliance status directly with Diotec Semiconductor before integration. Confirm that the D2PAK-7L package dimensions match your PCB footprint requirements. Ensure that the thermal design accounts for the 55mΩ on-resistance under expected operating currents to maintain junction temperatures within safe limits during continuous operation.
Selection Notes
Select this component when a 40V N-channel MOSFET with high current capacity is required for automotive or industrial use. The 50A continuous drain current makes it suitable for load switching applications. Consider the D2PAK-7L package for its superior heat dissipation compared to smaller surface-mount options. Verify compatibility with gate drive voltages given the standard logic-level thresholds typical for this class of devices.
