DTA123JUA from Slkor SLKORMICRO Elec, 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 pin of the built-in bias-resistor inverter; the input voltage VIN is rated -12 V to +5 V (Maximum Ratings), and VI(on) is -1.1 V max at IO=-5 mA. |
| 2 | GND | power_in | Ground reference pin for the device; the datasheet gives no separate limit for this pin. |
| 3 | OUT | output | Open-collector-type output of the digital transistor, rated IO = -100 mA maximum, with VCC supply up to -50 V and VO(on) of -0.3 V max at IO/II = -5 mA/-0.25 mA. |
