DDTA115TCA-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 of the PNP pre-biased transistor, driven through the built-in series resistor R1 of 100kΩ nominal (±30% tolerance), with emitter-base voltage limited to -5 V. |
| 2 | E | passive | Emitter terminal of the PNP transistor, with emitter-base breakdown voltage rated at -5 V minimum. |
| 3 | C | passive | Collector terminal of the PNP transistor, rated for -50 V collector-base and collector-emitter voltage and -100 mA maximum collector current. |
