DTC143ZUAT106 from ROHM Semicon, in a SOT-323(SC-70). 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 (EMITTER) | power_in | Ground / emitter of the built-in NPN transistor; R2 (47kΩ) connects between this pin and the input base node. |
| 2 | IN (BASE) | input | Input / base connected through built-in R1 = 4.7kΩ, with input voltage VI(off) max 0.5V, VI(on) min 1.3V and absolute maximum VIN of -5 to 30V. |
| 3 | OUT (COLLECTOR) | output | Output / collector of the built-in NPN transistor, rated for VCC 50V and IO 100mA maximum. |
