DDTA124XUA-7-F from Diodes Incorporated, 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 | IN | input | Input terminal (base of the PNP with built-in bias resistors); for DDTA124XUA the input voltage (1) to (2) is rated +10 V to -40 V. |
| 2 | GND | power_in | Common ground and reference terminal (emitter); all input and supply voltages are specified relative to this pin. |
| 3 | OUT | output | Output terminal (collector); supply voltage VCC (3) to (2) is rated -50 V maximum and output current for DDTA124XUA is rated -50 mA. |
