DTA143TUAT106

ROHM Semicon · Digital Transistors · SOT-323

DTA143TUAT106 from ROHM Semicon, in a SOT-323. 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; VEBO limit is -5 V.
2 BASE input Base input through built-in R1 = 4.7 kΩ (3.29 to 6.11 kΩ), so no external input resistor is needed.
3 COLLECTOR passive Collector of the built-in PNP transistor; VCEO is -50 V and IC is -100 mA max.
