KTC3875S-Y
Shikues · Bipolar (BJT) · SOT-23
KTC3875S-Y from Shikues, 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 datasheet gives a maximum base current IB of 30 mA (Ta = 25°C). |
| 2 | Emitter | passive | Emitter terminal of the NPN transistor; the datasheet gives a maximum emitter-base voltage VEBO of 5 V. |
| 3 | Collector | passive | Collector terminal of the NPN transistor; the datasheet gives a maximum collector-emitter voltage VCEO of 50 V, maximum collector current IC of 150 mA, and power dissipation Ptot of 200 mW. |
