BC847BT from CBI, 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 | B | input | Base of the NPN transistor; VEBO max is 6 V for BC847T and VBE(on) is 580 mV min to 700 mV max at VCE = 5 V, IC = 2 mA. |
| 2 | E | passive | Emitter of the NPN transistor, the common return for collector current, with collector current IC rated at 100 mA continuous and 200 mA peak. |
| 3 | C | passive | Collector of the NPN transistor; VCEO max is 45 V and VCBO max is 50 V for BC847T, with IC of 100 mA continuous. |
