Changjing · Digital Transistors · SOT-23
DTA114ECA 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 terminal of the built-in bias-resistor inverter; the datasheet's maximum input voltage (VIN) is -40 V to +10 V. |
| 2 | GND | power_in | Ground reference terminal of the device; the datasheet gives no separate electrical limit for this pin. |
| 3 | OUT | output | Output terminal of the transistor; the maximum ratings give an output current (IO) of -50 mA and a peak collector current (ICM) of -100 mA. |
