Single Resistor Digital Transistors, ON SemiconductorStandardsManufacturer Part Nos with S or NSV prefix are automotive qualified to AEC-Q101 standard.Digital Transistors, ON SemiconductorResistor-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.
