KEXIN · Bipolar Transistors - BJT · SOT-23
2SC2734-R25 from KEXIN, 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 NPN transistor; the emitter-base breakdown voltage VEBO is 3 V minimum with IE = 100 μA and the emitter cut-off current IEBO is 0.1 μA maximum at VEB = 3 V. |
| 2 | Emitter | passive | Emitter terminal of the NPN transistor; the absolute maximum emitter-base voltage VEBO is 3 V and the continuous collector current rating IC is 50 mA. |
| 3 | Collector | passive | Collector terminal of the NPN transistor; the absolute maximum collector-emitter voltage VCEO is 11 V and the collector-base voltage VCBO is 20 V, with collector power dissipation PC of 150 mW. |
