Product details

The Infineon BSZ0904NSIATMA1 is a 30 V N-channel OptiMOS™ power MOSFET in a PG-TSDSON-8-FL surface-mount package.

Body diode and the Schottky feature

The datasheet lists a Schottky diode integrated in the body diode structure. This reduces the reverse-recovery charge and softens the turn-off of the body diode, which matters in synchronous-rectifier stages and half-bridge converters where the body diode conducts during dead time.

Frequently asked questions

Is BSZ0904NSIATMA1 going obsolete?

No — the part is listed as Active with no end-of-life or NRND status. Infineon continues production under the OptiMOS™ series.

Can BSZ0904NSIATMA1 be used for battery protection?

Yes — the 30 V Vdss, 40 A continuous drain, and 4 mOhm Rds(on) make it suitable for lithium-ion battery protection circuits in power tools, e-bikes, and portable equipment where low on-resistance minimises heating during high discharge currents.
