Transistor refers to all single components based on semiconductor materials, including diodes, triodes, field-effect tubes, SCRs, etc. made of various semiconductor materials.
Transistor sometimes refers to transistor triode. Transistors are divided into 2 primary classifications: bipolar transistors (BJT) as well as field result transistors (FET). Transistors have three poles; the three poles of a bipolar transistor are composed of N-type and P-type emitter (Emitter), base (Base) and collector; the three poles of a field effect transistor are source (Source), gate (Gate) and drain (Drain).
Transistor is a semiconductor device, amplifier or electronically controlled switch commonly used. Transistors are the fundamental foundation that manages the procedure of computer systems, cell phones, and all various other modern electronic circuits. Because of their fast response time and high accuracy, transistors can be used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Transistors can be packaged individually or in a very small area that can hold one hundred million or more parts of a transistor integrated circuit.
