BSZ034N04LSATMA1

BSZ034N04LSATMA1 is the full order code for the Infineon BSZ034N04LS, an OptiMOS N-channel MOSFET in a PG-TSDSON-8 package (PQFN 3 x 3 mm) with fused leads. It is rated 40 V with RDS(on) of 3.4 milliohms maximum at 10 V gate drive (4.6 milliohms at 4.5 V), 40 A continuous drain current at 25 C and 160 A pulsed, at 25 nC typical gate charge. Selection advice: the small PQFN footprint with fused leads suits high-density point-of-load and OR-ing stages where a DPAK device will not fit, but the 3 x 3 mm pad needs deliberate copper area and via stitching to reach the headline current - check the board thermal design, not just the silicon rating. Infineon's product page lists the BSZ034N04LSATMA1 order code with product status Active. Parameters verified against Infineon documentation.
