25 V N-channel OptiMOS™ — what the ratings mean for the load
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.
Temperature range and environment
Junction temperature range is -55°C to 150°C. Power dissipation is 2.1 W at ambient and 30 W at case.
Package and mounting
The PG-TSDSON-8-FL package has an exposed drain pad requiring a thermal via pattern under the part.
Lifecycle and compliance
The BSZ031NE2LS5ATMA1 is listed as Active on the lifecycle record, with RoHS3 compliance confirmed. No end-of-life notice or last-time-buy schedule is associated with this part. The ROHS3 compliance covers the current regulatory requirements for EU and most global markets.
