What this part is and where it fits
The Infineon AUIRF7737L2TR is an N-channel enhancement-mode MOSFET from the HEXFET family. It is rated for a drain-to-source voltage of 40 V and a continuous drain current of 156 A at the case temperature (Tc) of 25°C, with a maximum Rds(on) of 1.9 mOhm at a 10 V gate drive.
Package and mounting — DirectFET L6 specifics
The DirectFET Isometric L6 is a leadless surface-mount package with a large solderable drain pad on the bottom and small source/gate pads. It requires a solder-paste stencil with specific aperture design to avoid solder bridging between the drain pad and the source pads.
Lifecycle and compliance
It is ROHS3 compliant, with no exemptions for lead or other restricted substances. The series is the Infineon HEXFET family, a long-running and widely second-sourced platform.
