BC817-40,215

BC817-40,215 is the tape-and-reel ordering code for the -40 gain rank of the Nexperia BC817 NPN transistor in SOT-23, with the full orderable part number verified against the maker’s data. Verified figures for the -40 rank: a current gain of 250 to 600 at 1 V collector-emitter voltage and 100 mA collector current — the rank band is the specification, and base-type or other-rank figures do not apply to this code — collector-emitter voltage of 45 V maximum, collector current of 500 mA maximum and collector-emitter saturation voltage of 700 mV maximum. Lifecycle wording stays neutral: no status field for this exact code was captured word-for-word, so none is claimed. Selection advice: BC817 ranks are separate order codes, so an offer of the unranked base type or another rank does not carry this code’s 250 minimum gain; match the full BC817-40,215 string when approving substitutes, and do not substitute documentation from the BC817K-Q sub-family, which is a different series. Parameters verified against the Nexperia BC817 datasheet (-40 rank row).
