Digital transistors simplify circuit design

Taiwan Semiconductor, the power semiconductor specialist with over 30 years of market experience, will showcase its new series of digital transistors with single polarity NPN or PNP. The digital transistors, also known as BRT (Bias Resistor Transistor), 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, furthermore the leakage current will be absorbed and shunted to ground in order to prevent malfunction. New series is available in SOT-23, SOT-323, SOT-523 and TO-92 packages. They include a resistance ratio R1/R2 of 4.7 – 0.046, with an output voltage range of 30 – 50V. Typical applications are Laptops, PCs, PDAs.
