BC848BW

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-323

BC848BW from Yangzhou Yangjie Elec Tech, in a SOT-323. 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; the datasheet states no pin-specific limit beyond VEBO 6 V maximum emitter-base voltage.
2 E passive Emitter of the NPN transistor; VEBO is 6 V max and collector current IC is 0.1 A max.
3 C passive Collector of the NPN transistor; for the BC848 types VCBO is 30 V max, VCEO is 30 V max, and IC is 0.1 A max.
