DTA143ZETL from ROHM Semicon, in a SOT-416. 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 | GND (+) / emitter of the built-in PNP transistor, the common return of the R2 bias resistor in the DTA143ZE (SOT-416/EMT3) inner circuit. |
| 2 | IN | input | IN (base) input through built-in R1 = 4.7kΩ, with input voltage rated -30 to 5 V, VI(off) max -0.5 V and VI(on) min -1.3 V. |
| 3 | OUT | output | OUT (collector) output rated for output current IO -100 mA and supply voltage VCC -50 V. |
