DTA143TETL 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 | EMITTER | passive | Emitter of the built-in PNP transistor; Pin 1 of the DTA143TE (EMT3) package. |
| 2 | BASE | input | Base input of the PNP transistor through the built-in 4.7kΩ R1 series resistor, which removes the need for an external input resistor. |
| 3 | COLLECTOR | passive | Collector of the built-in PNP transistor, rated for VCEO -50V and IC -100mA. |
