DTA114TU3T106

ROHM Semicon · Digital Transistors · SOT-323

DTA114TU3T106 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 PNP transistor; emitter-base voltage VEBO is limited to -5 V.
2 BASE input Base input through built-in 10 kΩ resistor R1 (7 to 13 kΩ) to the transistor base, so no external input resistor is needed.
3 COLLECTOR passive Collector of the PNP transistor; VCEO is -50 V and collector current IC is -100 mA maximum.
