RN2303 from TOSHIBA, in a SOT-323. 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 through the built-in 22 kΩ bias resistor R1 (R2 = 22 kΩ); VEBO rating is -10 V. |
| 2 | Emitter | passive | Emitter of the PNP bias-resistor transistor, normally tied to the positive supply; collector current is limited to -100 mA. |
| 3 | Collector | passive | Collector output of the PNP transistor; VCEO and VCBO are rated -50 V and IC is -100 mA maximum. |
