S8050

S8050 is an NPN transistor from CJ (Jiangsu Changjing) in SOT-23, verified against the Changjing datasheet, which prints package marking J3Y for this code. The datasheet ranks the device L (hFE 120 to 200), H (200 to 350) and J (300 to 400); the candidate line corresponds to the H rank, and the figures in this row are the H-rank figures: collector-base voltage of 40 V, collector-emitter voltage of 25 V, collector current of 500 mA maximum, collector power dissipation of 300 mW, an hFE(1) of 200 to 350 for this rank and collector-emitter saturation voltage of 0.6 V maximum. The order-code form is stated plainly: this page carries the bare S8050 code with the H rank (RANGE 200-350) named here, because the captured Changjing material does not print a separate rank-suffixed order string, and that form is left for confirmation at review. Selection advice: do not confuse this code with the SS8050 row in this catalog (a 1.5 A Changjing sibling) or with the S8550 PNP series — the rank band is the specification, so state the 200-350 gain band in your RFQ when it matters. Parameters verified against the Changjing S8050 datasheet (H rank).
