The 1800 pF input capacitance at 25 V drain-source is moderate for a 70 A device, so the gate drive loop — trace inductance and driver output impedance — will dominate the switching edge, not the FET's own capacitance. Low Qg also reduces cross-conduction losses in half-bridge topologies where dead time is tight. ## Package and mounting — PowerFlat with wettable flanks The 8-lead PowerFlat (5x6 mm) package uses wettable flanks, which means the side pads are solderable — this allows automated optical inspection (AOI) of the solder joints after reflow, a requirement for automotive-grade assembly. The large exposed pad on the bottom conducts heat to the PCB copper plane; the 72 W power dissipation rating assumes a thermal pad with adequate via array and a 2 oz copper pour on the top layer. ## Active production and compliance status It is ROHS3 compliant and qualified to AEC-Q101, so it meets the automotive stress-test requirements for temperature cycling, high-temperature reverse bias, and humidity.","metaTitle":"STL70N4LLF5 MOSFET N-CH 40V 70A PowerFlat, AEC-Q101","metaDescription":"STripFET V N-channel MOSFET, 40V drain-source, 70A continuous drain, 6.5mOhm Rds(on) at 10V.
