markdownKTC3875S-Y-RTK
KEC Semicon · Bipolar (BJT) · SOT-23
KTC3875S-Y-RTK from KEC Semicon, 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 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 5 V and emitter-side current through the base limit IB at 30 mA. |
| 2 | BASE | passive | Base terminal of the NPN transistor; base current is rated at 30 mA maximum (IB). |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor; ratings are VCBO 60 V, VCEO 50 V, collector current IC 150 mA and collector power dissipation PC 150 mW. |
