The DTA144WUA is a PNP digital transistor with built-in bias resistors, housed in a SOT-323 (UMT3) package. It has a maximum collector current of -100 mA and a collector-emitter voltage of -50 V. The device includes an input resistor of 47 kΩ and a second resistor of 22 kΩ, enabling inverter circuit design without external components. It supports a junction temperature up to 150 °C and is RoHS compliant. The package dimensions and tape reel specifications for SOT-323 are standardized at 180 mm reel size and 8 mm tape width, with 3000 pieces per reel.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
