30 V N-channel switch for low-voltage power rails
The Infineon IPB22N03S4L-15ATMA1 is an N-channel power MOSFET from the OptiMOS™ series, rated for 30 V drain-to-source voltage and 22 A continuous drain current at 25 °C case temperature. It comes in a surface-mount PG-TO263-3-2 (D²Pak) package. The junction temperature range is -55 °C to 175 °C.
Rds(on) and gate charge — what they mean for the design
Maximum on-resistance is 14.6 mOhm at 22 A with a 10 V gate drive. The gate charge is 14 nC at 10 V. Input capacitance is 980 pF at 25 V drain-source.
Where this part fits in the cycle
The IPB22N03S4L-15ATMA1 is listed as Active with no NRND or last-time-buy flags. It is a current-production Infineon OptiMOS part, not a phase-out or allocation-risk line. For a BOM freeze, this means no immediate LTB pressure — you can qualify it into a new design without worrying about an imminent end-of-life notice.
