175 °C junction — where this part lives comfortably
The IPB049N08N5ATMA1: The -55 °C to 175 °C operating junction temperature range covers automotive under-hood environments and industrial enclosures. The 125 W power dissipation at case temperature gives headroom for sustained high-current operation.
Gate drive and switching — what the numbers tell you
The 3.8 V maximum gate threshold at 66 µA means the part is fully enhanced with a 10 V gate signal; the drive voltage range of 6 V to 10 V for minimum Rds(on) lets you use a 10 V rail for lowest conduction loss or a 6 V rail to reduce gate-drive losses. The 3770 pF input capacitance at 40 V drain-source is the load the gate driver sees. The ±20 V maximum gate-source rating gives margin against ringing on long gate traces.
Package and ordering — which exact code you need
This MPN is the Tape & Reel (TR) variant of the D²Pak (TO-263-3) package; a Cut Tape (CT) option is also listed under the same base code. If your pick-and-place line runs reels, this is the ordering code. The PG-TO263-3 supplier device package is the Infineon internal designation. ROHS3 compliant per the lifecycle record.
