40 V, 75 A N-channel TrenchMOS with integrated current sense
The device is qualified to AEC-Q101, making it suitable for under-hood and chassis-domain automotive applications such as electric power steering, engine cooling fans, and DC motor drives.
What the 8 mOhm Rds(on) means for your BOM
The 84 nC typical gate charge at 10 V means the driver needs to source and sink enough peak current to switch the gate quickly; a standard automotive gate-driver IC with 2 A to 4 A peak output handles it cleanly. The 3140 pF input capacitance at 25 V drain-source also informs the switching speed and driver sizing.
Integrated current-sensing FET — no external shunt needed
A distinguishing feature of this part is the integrated current-sensing FET (marked as FET Feature: Current Sensing). This allows the designer to monitor load current by measuring the voltage across a small sense resistor in the source leg of the sense FET, eliminating the power dissipation and board area of a conventional high-current shunt resistor. For automotive loads where overcurrent detection or closed-loop current control is required, this feature simplifies the bill of materials and reduces PCB thermal stress.
Package and mounting: D²Pak (TO-263-5) with exposed tab
The part comes in a TO-263-5 (D²Pak) surface-mount package with four leads plus a large exposed drain tab (SOT-426 equivalent).
Temperature range and automotive qualification
The AEC-Q101 qualification means the part has passed the stress tests required for automotive-grade components: high-temperature reverse bias, temperature cycling, and humidity bias.
