BC846AQ

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-23

BC846AQ from Yangzhou Yangjie Elec Tech, in a SOT-23. 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; drives the device, with VEBO limited to 6 V and VBE(sat) max 1.1 V at IC=100mA, IB=5mA.
2 E passive Emitter of the NPN transistor; emitter-base breakdown V(BR)EBO min 6 V at IE=10μA.
3 C passive Collector of the NPN transistor; BC846AQ VCBO 80 V, VCEO 65 V, continuous IC 0.1 A.
