S8050-J3Y

S8050-J3Y is an NPN transistor from JSMSEMI in SOT-23, carrying the J3Y package marking in its order string. Verified figures: collector-base voltage of 40 V, collector-emitter voltage of 25 V, a continuous collector current of 300 mA and collector dissipation of 300 mW, collector-emitter saturation voltage of 0.6 V maximum at 500 mA, a transition frequency of 150 MHz minimum (at 6 V and 20 mA), and an hFE(1) range of 120 to 350 at 50 mA, split into L (120 to 200) and H (200 to 350) ranks — this maker’s table has no J rank, and 350 is its ceiling. Two cautions define this page. The figures differ from the CJ S8050 elsewhere in this catalog, whose table runs to 400 with a J rank: the two pages are different makers’ devices under a shared designation, and neither table substitutes for the other. And the maker attribution rests on the maker’s own document: the captured datasheet carries the JSMSEMI header and jsmsemi.com footer, with the J3Y marking drawn on its SOT-23 package figure. One boundary stays on the record: the document’s title is S8050 and J3Y is the package marking, so the compound order string is the marketplace form of this maker’s device rather than a string printed in its datasheet. Selection advice: state the 120 to 350 gain range in your RFQ when the band matters, so a 400-ceiling offer is not booked against this code by mistake. Parameters verified against the JSMSEMI S8050 datasheet as captured.
