WebJan 2, 2024 · By combining the two parameters α and β we can produce two mathematical expressions that gives the relationship between the different currents flowing in the transistor. The values of Beta vary from about 20 for high current power transistors to well over 1000 for high frequency low power type bipolar transistors. WebDec 21, 2024 · A transistor, also known as a BJT (Bipolar Junction Transistor), is a current driven semiconductor device which can be used to control the flow of electric current in which a small amount of current in the Base lead controls a larger current between the Collector and Emitter.

The output device that is switched by this transistor is called a load. The power generated in the switch transistor is very low: In the OFF state: power = IC × VCE, but IC = 0, so power is zero. grand lux king of prussia
