ADTA114ECAQ-7 from Diodes Incorporated, 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; the input voltage is rated from +10 V to -40 V relative to pin 2, and the device is guaranteed off below -0.5 V and on above -3 V input. |
| 2 | GND | power_in | Common ground reference for the input voltage (pin 1) and the supply voltage (pin 3), as shown in the equivalent inverter circuit. |
| 3 | OUT | output | Open-collector-style output; the supply voltage VCC is rated at -50 V maximum from pin 3 to pin 2, with output current IO of -50 mA and collector current IC of -100 mA maximum. |
