Dual Resistor Digital Transistors, InfineonA 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, InfineonResistor-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.
