Product details

The Infineon BSZ031NE2LS5ATMA1 is a 25 V N-channel MOSFET from the OptiMOS™ series, housed in a PG-TSDSON-8-FL surface-mount package. It is designed for low-voltage dc-dc conversion, load switching, and OR-ing applications where conduction loss matters. The headline numbers are a continuous drain current of 19 A at 25°C ambient (Ta) and 40 A at the case (Tc), with a maximum Rds(on) of 3.1 mOhm at 20 A and 10 V gate drive. Gate charge is 18.3 nC at 10 V; input capacitance is 1230 pF at 12 V Vds.

Power dissipation is 2.1 W at ambient and 30 W at case.
