Gate charge and switching speed
The CSD22204WT: Total gate charge Qg is 24.6 nC at 4.5 V. Input capacitance Ciss is 1130 pF at 4 V drain-source.
Thermal headroom for tight layouts
Junction temperature range extends from -55 °C to 150 °C, covering both military cold-soak and under-hood hot spots. Maximum power dissipation is 1.7 W at 25 °C ambient on a standard PCB — derate above 25 °C per the datasheet's thermal impedance curves. The DSBGA's exposed backside pad (if connected to a copper plane) improves heat spreading, but the 1.7 W ceiling limits the continuous current to 5 A only with adequate board copper.
Active lifecycle — no obsolescence pressure
The part is ROHS3 compliant. For new designs, the active lifecycle means no forced redesign from obsolescence, though the DSBGA footprint locks the board into a fine-pitch assembly process.
