hongjiacheng · Bipolar (BJT) · SOT-23
S9018 from hongjiacheng, 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 | B | passive | Base terminal of the S9018 NPN transistor; the datasheet's function diagram labels this pin B. Base-emitter saturation voltage is specified at IC=10mA, IB=1mA, with a maximum of 1.4 V. |
| 2 | E | passive | Emitter terminal of the S9018 NPN transistor; the datasheet's function diagram labels this pin E. Emitter-base breakdown voltage is 5.0 V minimum at IE=100μA. |
| 3 | C | passive | Collector terminal of the S9018 NPN transistor; the datasheet's function diagram labels this pin C. Collector-base breakdown voltage is 30 V minimum and collector current is rated at 50 mA. |
