IAUTN10S7N009ATMA1

IAUTN10S7N009ATMA1 is an Infineon OptiMOS 7 100 V N-channel automotive MOSFET in the PG-HSOF-8 (TOLL) leadless power package, supplied on tape and reel — the 100 V high-current option of the TOLL group, for 48 V systems with severe load-dump exposure and other 100 V-class nodes. Its 0.88 mΩ maximum RDS(on) at 10 V gate drive and 350 A rating hold conduction loss at 100 A to about 8.8 W, and the typical gate charge of 187 nC keeps the driver stage modest for a die of this size. The 10 x 12 mm leadless footprint suits automated optical inspection, and the junction range reaches +175 °C. Selection advice: within the 100 V class this TOLL code is the high-current path; the SSO10T IAUCN line is the alternative where top-face cooling and a 5 x 7 mm footprint matter more than current — its N025T code is 2.5 mΩ at 175 A and the L290T code trades resistance for direct logic-level drive. If the bus never leaves the 48 V envelope, the 80 V TOLL pair beats this code on resistance. Infineon lists the part as active and preferred. Parameters verified against Infineon documentation.
