DDTA113ZUA-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 (base, B) through R1; input voltage measured pin 1 to pin 2 is +5 to -10 V for the DDTA113ZUA. |
| 2 | GND(+) | power_in | Ground/positive reference (emitter, E) of the PNP pre-biased transistor, with R2 connected between input and this pin. |
| 3 | OUT | output | Output (collector, C); supply voltage VCC pin 3 to pin 2 is -50 V max and output current is -100 mA max. |
