BCX56-16Q

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-89

BCX56-16Q from Yangzhou Yangjie Elec Tech, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base of the NPN transistor, left lead in the top-view diagram; the datasheet's emitter-base voltage rating is VEBO 5 V.
2 C passive Collector, centre lead, internally connected to the collector tab; ratings are VCEO 80 V, VCBO 100 V and IC 1 A.
3 E passive Emitter of the NPN transistor, right lead in the top-view diagram.
