DDTA124TUA-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, connected to the transistor base through the built-in input resistor R1; the input voltage must stay within the per-variant limits in the Maximum Ratings table (for example +10 V to -40 V for DDTA124XUA). |
| 2 | GND | power_in | Ground/emitter reference terminal (labelled GND(+) in the datasheet) that is common to the input and output circuits and is also the base-emitter resistor R2 reference. |
| 3 | OUT | output | Output terminal, the collector of the PNP transistor; output current is limited per variant, to -100 mA for most parts and -50 mA for DDTA124XUA in the Maximum Ratings table. |
