Rds(on) and package power — the derating reality
At 3 A, the 121 mOhm Rds(on) produces conduction loss above the 500 mW package power dissipation rating. Continuous 3 A requires aggressive thermal management or pulsed operation.
Sourcing and lifecycle
The CSD17484F4 is listed as Active in production and ROHS3 compliant. No official second source or pin-compatible cross is listed in the TI FemtoFET™ family; the 3-PICOSTAR footprint is unique to this series.
