60V, 45A N-channel in a rework-friendly D2Pak
The IPB45N06S4L08ATMA3 is an Infineon OptiMOS-T2 N-channel MOSFET rated for 60 V drain-source and 45 A continuous drain at 25°C case temperature. It comes in a TO-263-3 (D2Pak) surface-mount package — the large copper tab makes it one of the more forgiving power packages under a hot-air station, as long as you preheat the board to keep the tab from wicking heat away too fast.
That figure is specified at 25°C junction; expect it to rise by roughly 50% at 125°C, so budget the conduction loss with the hot value in mind. Total gate charge is 64 nC at 10 V. The input capacitance is 4780 pF at 25 V drain-source, which sets the switching energy and the driver's peak current requirement.
The 175°C TJ max gives headroom for transient overloads. The PG-TO263-3-2 package (D2Pak) has three leads plus the tab. A 2 oz copper pour of at least 6 cm² is a reasonable starting point for continuous operation near the rating.
