DTA113ZCA from Changjing, 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 | IN | input | Input pin to the built-in bias-resistor network (R1 typ. 1 kΩ); the input voltage is rated from -10 V to +5 V, and VI(off) is -0.3 V max. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | OUT | output | Output pin of the transistor; output current is rated to -100 mA maximum, with a supply voltage VCC of -50 V maximum. |
