CJ3407

CJ3407 is a P-channel MOSFET from CJ (Jiangsu Changjing) in SOT-23, verified against the current version 2.0 datasheet on the maker’s own site, which lists the code with AEC-Q101 qualification. Verified figures: drain-source voltage of -30 V, continuous drain current of -4.1 A, gate-threshold voltage of -1 V minimum, -1.4 V typical and -2.1 V maximum, and on-state resistance of 50 mΩ typical and 60 mΩ maximum at -10 V gate drive (68 mΩ typical and 87 mΩ maximum at -4.5 V). The threshold ceiling needs care: an older revision of this datasheet printed -3 V as the maximum, and that figure belongs to the superseded document — the -2.1 V ceiling of the current manual is the one an offer should be checked against. Selection advice: budget the on-resistance at your actual gate voltage; the -4.5 V row, not the -10 V headline, governs a logic-driven load switch. Parameters verified against the Changjing CJ3407 datasheet, version 2.0.
