BC848B
HXY MOSFET · Bipolar (BJT) · SOT-23
BC848B from HXY MOSFET, 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 | BASE | input | Base terminal of the BC848B NPN transistor; the datasheet gives the emitter-base breakdown voltage as 6 V minimum (IE=10µA, IC=0) and VEB=5V for emitter cut-off current test. |
| 2 | EMITTER | passive | Emitter terminal of the BC848B NPN transistor; the datasheet rates the emitter-base voltage VEBO at 6 V for this pin. |
| 3 | COLLECTOR | passive | Collector terminal of the BC848B NPN transistor; the BC848 variant is rated at 30 V for both collector-base (VCBO) and collector-emitter (VCEO) voltage with a 100 mA collector current limit. |
