IRF540NSTRLPBF

IRF540NSTRLPBF is the full orderable part number for the Infineon IRF540NS N-channel MOSFET in D2PAK on tape and reel (left orientation, 800 pieces per reel), verified on the maker’s product page, whose Recommended table lists this exact code with Product Status: active, MSL 1 and lead-free/halogen-free stated. Verified figures: drain-source voltage of 100 V maximum, continuous drain current of 33 A maximum at a 25 °C case temperature, on-state resistance of 44 mΩ maximum at 10 V gate drive, total gate charge of 47.3 nC typical, gate-threshold voltage of 2 V minimum, 3 V typical and 4 V maximum, gate-source voltage of ±20 V maximum, junction temperature of 175 °C maximum, and junction-to-case thermal resistance of 1.1 K/W maximum. The selection point is a 100 V surface-mount trench MOSFET whose D2PAK tab carries the thermal load in motor drives, battery switches and DC/DC stages. Selection advice: the full string is the specification — the S element is the D2PAK surface-mount form of the IRF540N family, and the through-hole sibling is a different order code; quote IRF540NSTRLPBF in full.
