Infineon IAUT240N08S5N019

IAUT240N08S5N019 - 80V Automotive MOSFET targeting 48V applications like Inverter, Power Distribution, DCDC and medium power 48V Auxiliaries

Sample of Infineon's IAUT240N08S5N019 MOSFET

Infineon’s 80V and 100V MOSFETs perfectly support hardware engineers in the rapidly growing 48V Electronic Control Units (ECU) market. The MOSFET family is offered in different package types covering high power 48V applications like auxiliary inverter, starter generators and battery switches, medium power like 48V e-Turbo and e-climate compressors as well as lower power 48V auxiliaries.

The IAUT240N08S5N019 is an 80V Automotive MOSFET in 12 x 10 mm² TO-leadless (TOLL) package with an RDS(on) of 1.9mR. With its low resistance and the capability of parallel usage it is suiting the requirements for 48V auxiliary inverters. Next to this the IAUT240N08S5N019 is also targeting the medium power 48V applications like 48 Power Distribution, DCDC converter and 48V Auxiliaries.



  • Lowest RDS(on) MOSFETs down to 1.2mR (80V) and 1.5mR (100V) in 12 x 10 TOLL package
  • PIN- and function-compatible MOSFET for Al based insulated metal substrates (IMS) in package with gullwing leads available (IAUS240N08S5N019 in TOLG)
  • Low package resistance and minimized stray inductance
  • Variety of package and RDS(on) options for different application power requirements
  • Tightened VGS thresholds



  • High power and current density
  • Optimized switching behavior
  • Reduced conduction losses
  • Paralleling of MOSFETs



  • 48V Auxiliary Inverter
  • 48V Power Distribution
  • 48V DCDC Converter
  • 48V Auxiliaries
