CJ2310

CJ2310 is an N-channel MOSFET from CJ (Jiangsu Changjing) in SOT-23, verified against the Changjing datasheet, which prints package marking S10 for this code. Verified figures: drain-source breakdown voltage of 60 V minimum, continuous drain current of 3 A, gate-threshold voltage of 0.5 V minimum and 2 V maximum, on-state resistance of 82 mΩ typical and 105 mΩ maximum at 10 V gate drive, and input capacitance of 247 pF typical. The selection point is a 60 V SOT-23 switch with a guaranteed sub-2 V threshold ceiling; the on-resistance figures are 10 V-drive figures, so a logic-level design should re-check the drop at its actual gate voltage before budgeting this part. Selection advice: keep this code separate from the CJ2310S, a different Changjing variant with its own table, and from same-named 2310 offerings of other makers, whose resistance figures differ. Parameters verified against the Changjing CJ2310 datasheet.
