MMBT4401LT1G

MMBT4401LT1G is an onsemi NPN general-purpose switching transistor in SOT-23, tape and reel, 3,000 per reel, lead-free (the G suffix) — for driver stages, small-signal switching and discrete logic. This is onsemi's part and is recorded separately from the Diotec MMBT4401 also listed on this site: the type number is shared across makers, but the datasheets are not interchangeable, so the maker on the BOM line decides which table governs. On onsemi's table: collector-emitter breakdown 40 V, collector-base 60 V, emitter-base 6.0 V; hFE is 100 to 300 at IC = 150 mA and VCE = 1.0 V; saturation voltage is 0.40 V maximum at IC/IB = 150/15 mA and 0.75 V maximum at 500/50 mA; transition frequency is 250 MHz minimum at IC = 20 mA, VCE = 10 V, measured at 100 MHz. Selection advice: quote the full LT1G code including the maker; a reel labelled only MMBT4401 does not establish onsemi origin. onsemi status wording for this code was not captured for this record, so no status is claimed here — the offered lot is confirmed against your requirement before quotation. Parameters verified against the onsemi MMBT4401LT1 datasheet.
