DTA043EEBTL 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 | IN | input | Input (base of the built-in PNP transistor) through R1 = 4.7kΩ; input voltage range is -30 to 10 V, VI(off) max -0.5 V and VI(on) min -2.2 V. |
| 2 | GND | power_in | Ground (+) terminal, the emitter of the built-in PNP transistor, with R2 = 4.7kΩ connected between it and the base. |
| 3 | OUT | output | Output (collector of the built-in PNP transistor) rated for supply voltage VCC of -50 V and output current IO of -100 mA. |
