RN4907 from TOSHIBA, in a SOT-363. 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 | Emitter1 | passive | Emitter of Q1, the PNP bias-resistor transistor; Q1 absolute maximum ratings are VCBO -50 V, VCEO -50 V, VEBO -6 V and IC -100 mA. |
| 2 | Base1 | input | Base of Q1 with built-in input resistor R1 (typ. 10 kΩ, range 7 to 13 kΩ), so no external base resistor is needed. |
| 3 | Collector2 | passive | Collector of Q2, the NPN bias-resistor transistor; Q2 absolute maximum ratings are VCBO 50 V, VCEO 50 V, VEBO 6 V and IC 100 mA. |
| 4 | Emitter2 | passive | Emitter of Q2, the NPN bias-resistor transistor. |
| 5 | Base2 | input | Base of Q2 with built-in input resistor R1 (typ. 10 kΩ, range 7 to 13 kΩ), so no external base resistor is needed. |
| 6 | Collector1 | passive | Collector of Q1, the PNP bias-resistor transistor. |
