DTA043ZUBTL

ROHM Semicon · Digital Transistors · SOT-323

DTA043ZUBTL 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 IN input Input (base) through built-in R1 = 4.7kΩ, with R2 = 47kΩ to the emitter; input voltage range -30 to 5 V.
2 GND power_in Ground (+) / emitter of the PNP digital transistor, the common reference for input and output.
3 OUT output Output (collector) with output current rated up to -100 mA and supply voltage VCC of -50 V.
