100 V N-channel MOSFET for automotive power switching
The STL45N10F7AG: The 100 V Vdss rating provides headroom for automotive bus applications.
Switching speed and gate drive requirements
Input capacitance Ciss is 1450 pF at 50 V drain-source. That capacitance, combined with the gate charge, determines the switching loss profile in hard-switched topologies like boost converters or motor-drive H-bridges.
AEC-Q101 qualification and junction temperature range
The 175 °C ceiling is critical for engine-bay or exhaust-adjacent mounting.
The 8-lead PowerVDFN (PowerFlat 5x6) surface-mount package dissipates 72 W (Tc).
The laser etch and date-code traceability should be verified against ST's factory marking guide when receiving material.
