IAUAN04S7N004AUMA1

IAUAN04S7N004AUMA1 is an Infineon OptiMOS 7 40 V N-channel automotive MOSFET in the PG-HSOF-5 (sTOLL) leadless power package, tape and reel — an established production code (launched April 2024) for designs that need TOLL-class current in a smaller footprint. The sTOLL outline measures 7 x 8 mm, roughly half the board area of the 10 x 12 mm PG-HSOF-8 family, yet this code still carries a 280 A rating with 0.39 mΩ maximum RDS(on) — conduction loss at 200 A is roughly 15.6 W. That density suits 12 V and 48 V distribution, motor pre-drivers and DC-DC stages where the full-size TOLL outline does not fit. Selection advice: note the order-code suffix — the sTOLL codes close with AUMA1, not the ATMA1 of their TOLL siblings, and the BOM must carry the complete string. Choose this N004 code over the N005 sTOLL sibling when the loss budget is tight; take the N005 where its 0.51 mΩ still meets the thermal design. Infineon lists the part as active and preferred.
