Key ratings and what they mean for the BOM
The AUIRF7732S2TR: Gate charge of 45 nC at 10 V is moderate: the device can be driven by a standard gate driver IC without excessive switching losses up to a few hundred kHz. The 1700 pF input capacitance at 25 V helps the designer size the gate drive circuit and predict switching times.
Package and mounting
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. The PCB footprint must include a thermal via array under the package to pull heat into an internal copper plane. Standard reflow profiles for lead-free solder apply; the package is compatible with automated pick-and-place.
