BC847T
Changjing · Bipolar (BJT) · SOT-523
BC847T from Changjing, in a SOT-523. 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 NPN transistor; the datasheet gives no pin-specific electrical limits, so the absolute maximum ratings apply (VEBO 6 V, IC 0.1 A continuous, PC 150 mW). |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives no pin-specific electrical limits, so the absolute maximum ratings apply (VEBO 6 V, IC 0.1 A continuous, PC 150 mW). |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet gives no pin-specific electrical limits, so the absolute maximum ratings apply (VCBO 50 V, VCEO 45 V, IC 0.1 A continuous, PC 150 mW). |
