ROHM Semicon · Digital Transistors · SOT-723
DTA144EMT2L from ROHM Semicon, in a SOT-723. 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 | Base input through built-in 47kΩ resistor R1, so no external input resistor is needed; VIN rated -40 to 10 V, with VI(off) max -0.5 V and VI(on) min -3.0 V. |
| 2 | GND | power_in | Emitter, connected to the positive/ground reference of the PNP digital transistor and to the built-in 47kΩ R2 resistor, with VCC rated -50 V. |
| 3 | OUT | output | Collector output of the PNP digital transistor, rated IO -30 mA (IC max -100 mA) with VO(on) max -300 mV at IO = -10 mA. |
