It handles a 25 V drain-to-source voltage and delivers up to 40 A continuous drain current at the case (Tc), with a 32 A rating at ambient (Ta). The headline number is the 1 mOhm maximum on-resistance at 10 V gate drive and 20 A — that milliohm figure keeps conduction losses low in a 12 V or 5 V rail, which is exactly where this part gets used: synchronous buck converters, load switches, battery protection, and OR-ing diodes in telecom or industrial gear.
The PG-TSDSON-8-FL package can sink conduction loss to the PCB copper through its exposed pad.
Package and mounting — PG-TSDSON-8-FL
The 8-PowerTDFN case (Infineon calls it PG-TSDSON-8-FL) is a surface-mount package with a large drain pad on the bottom. For a 40 A design, expect a multi-layer board with at least 2 oz copper and a dedicated thermal land.
