Digital transistors are transistors with resistors. Some have a resistor R1 in series at the base, and some have a resistor R2 in parallel between the base and the emitter. The resistor R1 and the resistor R2 can be matched in various ways. In this issue, Hottech introduces a digital transistor MMUN2214 with SOT-23 package, which can be used as a bipolar transistor with integrated base resistance. Its main functions are switching and signal amplification. Digital transistors can be used as high-frequency switches, analog signal control switches, digital signal conversion switches, audio and video signal switches and other fields.
