digital transistors Also known as Bias Resistor Transistors, a series of single-polarity  NPN or PNP digital transistors from Taiwan Semiconductor replace a single transistor and its external resistors. Integrating the Bias Resistors results in various advantages such as reduction in production costs because of saving space on the PCB, decreasing the number of components, and increasing production yield rates.The transistor operation is stabilised by converting the input voltage to current, and the leakage current is absorbed and shunted to ground. The series is available in SOT-23, SOT-323, SOT-523 and TO-92 packages. Features include a resistance ratio R1/R2 of 4.7 - 0.046 with an output voltage range from 30 - 50V.
