IAUCN10S7L290TATMA1

IAUCN10S7L290TATMA1 is the orderable tape-and-reel code for Infineon's OptiMOS 7 logic-level automotive MOSFET in the SSO10T package (PG-LHDSO-10, 5 x 7 mm). It is rated at 100 V with 28.6 mOhm maximum RDS(on) at a 10 V gate drive, a typical gate charge of only 5.1 nC and a 27 A maximum current at 25 degrees C, and its typical 1.6 V threshold lets it switch directly from low-voltage drive logic, with no driver stage. The exposed top face carries the heat path, so thermals do not depend on copper area beneath the device - valuable in dense zone controllers needing a 100 V, AEC-Q101 qualified switch for a modest load. Selection advice: the in-catalog IAUCN10S7N025TATMA1 is the same-package low-resistance 100 V option (2.5 mOhm, 175 A) for high-current paths; choose this L290T code where gate-drive simplicity matters more than conduction loss. Infineon lists this OPN as active and preferred in its OptiMOS 7 100 V SSO10T product brief. Parameters verified against Infineon documentation.
