Taiwan Semiconductor has showcased its new series of digital transistors with single polarity NPN or PNP. Also known as BRT (Bias Resistor Transistors), digital transistors replace single transistors and their external resistors.
Integrating the Bias Resistors results in various advantages such as the reduction in production costs because of space saving on the PCB, the decrease in the number of component parts and increase in production yield rates.
The transistor operation is stabilised by converting the input voltage to current, while the leakage current will be absorbed and shunted to ground in order to prevent malfunction.
The 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 KΩ, with an output voltage range of 30 - 50V.
