BC857CDW1T1G from onsemi, in a SOT-363. 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 | EMITTER 2 | passive | Emitter terminal of the second PNP transistor (Q2) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
| 2 | BASE 2 | passive | Base terminal of the second PNP transistor (Q2) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
| 3 | COLLECTOR 1 | passive | Collector terminal of the first PNP transistor (Q1) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
| 4 | EMITTER 1 | passive | Emitter terminal of the first PNP transistor (Q1) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
| 5 | BASE 1 | passive | Base terminal of the first PNP transistor (Q1) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
| 6 | COLLECTOR 2 | passive | Collector terminal of the second PNP transistor (Q2) in the dual device; the datasheet gives no pin-specific limit, so use the device maximum ratings (VCEO, VCBO, VEBO, IC). |
