BC847B,215

BC847B,215 is the full orderable part number for the Nexperia BC847B NPN general-purpose transistor in SOT-23 (TO-236AB), verified word-for-word on the maker’s chemical-content page at build time: orderable part BC847B,215, 12NC 933589590215, package SOT23 (TO-236AB), state RFS (released for supply). Verified figures: collector-emitter voltage of 45 V maximum, collector-base voltage of 50 V maximum, collector current of 100 mA maximum, total power dissipation in the 250 mW class, and the B gain rank’s DC current gain of 200 minimum, 290 typical and 450 maximum at 5 V collector-emitter voltage and 2 mA collector current. The selection point is a guaranteed 200-to-450 gain band in the standard BC847 small-signal footprint for switching and linear stages. Selection advice: the rank letter is the specification — other BC847 ranks are separate order codes with their own gain bands, and a rank substitution changes bias points in linear stages; quote the full BC847B,215 string including the packing suffix. Parameters verified against the Nexperia BC847 series datasheet and the maker’s chemical-content listing.
