Picking the right transistor for a project is surprisingly important, but many people do not understand why. It is because little transistors play large roles in how electronics function. Whether a project requires a 2N2243 transistors in New Jersey or another type of transistor, Visit us online to find the right part for the project.
BJT Transistor Construction
There are two main types of transistors Bipolar Junction Transistors (BJT) and Field Effect Transistors (FET). The 2N2243 is a BJT transistor. BJT transistors have three layers of semiconductor material: an emitter level, a base level, and a collector level. Each of these layers has a charge, and BJT semiconductors are subdivided into two groups: NPN and PNP. This classification refers to the charge of the semiconductor material used in each layer. NPN semiconductors have negative layers on the outside and an inner positive layer. PNP semiconductors have positive layers on the outside and an inner negative layer.
Are The Layers of Semiconductor Material Charged?
While the layers of semiconductor material may be labeled positive or negative, they are neutral. What earns them the label is how many free electrons they have available, which impacts how they operate as conductors or electricity.
How Transistors Work
Transistors work as either amplifiers or switches, which means that they work to change the incoming current. This is accomplished by the differences in the three layers of semiconductor material. The same concept works for amplification and switching, changing the input of energy to a more significant output. Therefore, a transistor can change the current going into a part of an electronic device.
The 2N2243
The 2N2243 is an NPN transistor that is designed to work in low power, regular voltage, low current applications. It comes in the TO5 package, which is a common package for transistors. It can withstand heat up to 200 degrees Celsius. Functional equivalents to the 2N2243 Transistors in Texas include the PN2907, BC560B, PN5134, 2N5769, MPSA12, 2N5225, 2N3706, 2N6724, and 2N5227 types of transistors. It may work in a project. The best way to find out is to ask a component’s professional, who can help guide the right component for a projects’s specifications.
