ROHM, DTD123YKT146 NPN Digital Transistor, 500 mA 50 V 2.2 kΩ, Ratio Of 4.5, Single, 3-Pin SOT-346

Digital Transistors, ROHM Semiconductor

Resistor-equipped bipolar transistors, also known as “Digital Transistors” or “Bias Resistor Transistors”, incorporating one or two integrated resistors. A single series input resistor, or a potential divider of two resistors, allows these devices to be directly driven from digital sources. Both single and dual transistor versions are available.
