RN1105MFV from TOSHIBA, in a SOT-723. 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 input of the NPN transistor, which has a built-in series bias resistor R1 of 2.2 kΩ and a base-emitter resistor R2 of 47 kΩ for RN1105MFV. |
| 2 | Emitter | passive | Emitter of the NPN transistor, normally connected to ground; emitter-base voltage rating is 5 V for RN1105MFV. |
| 3 | Collector | passive | Collector of the NPN transistor; collector-emitter voltage rating is 50 V and collector current rating is 100 mA. |
