What are the transistors symbols?
Table of transistor symbols
| Name | Description |
|---|---|
| NPN Bipolar Transistor | Allows current flow when high potential at base (middle) |
| PNP Bipolar Transistor | Allows current flow when low potential at base (middle) |
| Darlington Transistor | Made from 2 bipolar transistors. Has total gain of the product of each gain. |
What does the transistor represent?
A transistor basically acts as a switch and an amplifier. In simple words, we can say that a transistor is a miniature device that is used to control or regulate the flow of electronic signals. Transistors are one of the key components in most of the electronic devices that are present today.
What are the types of transistors *?
Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors: BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs). A bipolar transistor is a type of transistor that uses both electrons and holes as charge carriers.
What are examples of transistors?
An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer. An electronic device that controls the flow of an electric current, most often used as an amplifier or switch.
What is a transistor in simple words?
Definition of transistor 1 : a solid-state electronic device that is used to control the flow of electricity in electronic equipment and usually consists of a small block of a semiconductor (such as germanium) with at least three electrodes. 2 : a transistorized radio.
What is inside a transistor?
Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices.
How many junctions does a transistor have?
two
An NPN transistor comprises two semiconductor junctions that share a thin p-doped region, and a PNP transistor comprises two semiconductor junctions that share a thin n-doped region.
