DDTC115GCA-7-F from Diodes Incorporated, 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 | B | input | Base input, with built-in R2 (100kΩ nominal, ±30%) bleeder resistor between base and emitter; VEBO max 5V. |
| 2 | E | passive | Emitter of the NPN pre-biased transistor, normally tied to ground; emitter-base voltage limited to 5V. |
| 3 | C | passive | Collector output; VCEO 50V max, IC max 100mA, VCE(sat) max 0.3V at IC=10mA, IB=0.5mA. |
