The DirectFET™ Isometric SC package is a surface-mount can with a large solderable backside that acts as both the drain connection and the primary thermal path. Standard reflow profiles for lead-free solder apply; the package is compatible with automated pick-and-place.

Frequently asked questions
Does AUIRF7732S2TR have a direct replacement or equivalent?
No direct pin-compatible replacement is listed in the official records. The peer IPD50R950CEAUMA1 is a 500 V CoolMOS™ device with a much higher Rds(on) and lower current rating, so it is not a functional substitute. For a second-source option, consult the Infineon HEXFET portfolio in the same DirectFET SC package and voltage class.
