MMBTRC101SS from CBI, 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 | Input terminal, connected through the built-in R1 bias resistor (4.7 kΩ for MMBTRC101SS); input voltage absolute maximum is 20 V and -10 V for this variant. |
| 2 | Emitter | passive | Common emitter terminal, the reference for the input and output of the built-in bias-resistor NPN transistor; built-in R2 is 4.7 kΩ for MMBTRC101SS. |
| 3 | Collector | output | Output terminal; absolute maximum output voltage is 50 V and output current is 100 mA. |
