A range of bipolar junction transistors from Infineon equipped with integrated resistors allowing the devices to be directly driven from digital sources without additional components. Dual resistor devices have a series input resistor plus a resistor connected between the transistor base and emitter.

Digital Transistors, Infineon

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.
