BC846BW

Guangdong Hottech · Bipolar (BJT) · SOT-323

BC846BW from Guangdong Hottech, 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, shown at the bottom-left of the SOT-323 diagram; VEBO is 6 V max and VBE(ON) is 0.58-0.7 V at VCE=5V, IC=2mA.
2 E passive Emitter of the NPN transistor, shown at the bottom-right of the SOT-323 diagram; IC is 100 mA max and VEBO is 6 V max.
3 C passive Collector of the NPN transistor, the single lead on top of the SOT-323 diagram; VCBO is 80 V, VCEO is 65 V and IC is 100 mA max.
