ROHM Semicon · Digital Transistors · SOT-323
DTA143EUAT106 from ROHM Semicon, 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 | GND | power_in | Ground (+) / emitter of the built-in PNP transistor, connected to R2 and the common return of the inverter. |
| 2 | IN | input | Base input through built-in R1 = 4.7kΩ (R2 = 4.7kΩ to emitter); VIN range -30 to 10 V, VI(off) max -0.5 V and VI(on) min -3.0 V. |
| 3 | OUT | output | Collector output of the digital transistor, rated up to -100 mA output current and VCC -50 V. |
