Gate charge and switching profile
The RJK0660DPA-00#J5A: Total gate charge is 45 nC at 10 V. Input capacitance is 3600 pF at 10 V Vds.
Package and thermal path — 8-WPAK exposed pad
The supplier device package is 8-WPAK. The 65 W power dissipation rating assumes the exposed pad is properly heatsunk.
Lifecycle and compliance — active production
No last-time-buy risk on the horizon from the official record. The part ships in Tape & Reel (TR) — standard for automated pick-and-place.
What the 5.1 mOhm rating means for load-switch and converter designs
In a 12 V input, 5 V output buck converter at 10 A load, the MOSFET's conduction loss at 5.1 mOhm is about 0.5 W — manageable with a small heatsink pad. The 60 V Vdss gives 5x margin over a 12 V rail, or 1.25x margin on a 48 V telecom bus — adequate for most industrial supplies. The 40 A continuous rating means it handles inrush and short-circuit peaks without immediate failure, though the 65 W dissipation ceiling limits sustained overload.
