Transistors

Field effect, bipolar and IGBT transistors - all those three types can be found in the Micros store. Get acquainted with the usage of transistors and what are the differences between particular types. Please check why it is worth choosing products offered by us.

What is a transistor and what is it used for?

Transistor is a semiconductor that has the capability of amplifying the electric signal.

The device is characterised by small size, hence it replaced vacuum tubes used before. It is believed that one of the main factors for the electronic development acceleration in the recent decades was introducing transistors to the market. It was possible thanks to the capability of significantly amplifying the signal by using small and not so complicated elements. However, why in fact it turned out to be that important and what are the uses of transistors in present day electronics? Here are few examples:

  • It is the most important part of amplifiers; 
  • It is used as a structural element in semiconductor memory;
  • It takes part in a signal transmission, e.g. in phase shift modules and generators;

Types of transistors

It is hard to answer the question “What are transistors used for?” without explaining what are the differences between them. In Micros offer you will find every transistor that you might need. Our offer includes devices with a variety of applications, because our aim is to meet the needs of every customer. When it comes to transistors, we can distinguish three main types, and dozens of devices from each type can be found in the relevant product category in our store. The three main types are:

  • Field effect transistors
  • Bipolar transistors
  • IGBT transistors

We can assume that the field effect transistors are the most classic version of transistors. This invention is nearly 100 years old, however it is still incredibly useful. FET(Field Effect Transistor) consists of one semiconductor layer and the current is controlled by using the electromagnetic field.

Bipolar transistors, which are also available in our offer, are made up of three semiconductor layers, and each one of them represents a different type of semiconductivity. IGBT transistors on the other hand are a variety of bipolar transistors equipped with additional insulated gate.

Transistors in our offer

Our offer includes transistors with a vast variety of applications. We provide numerous FET models, called unipolar, which are essential parts of integrated circuits or switches. If you need parts for current amplifiers, choose our bipolar transistors. Moreover, essential parts for photovoltaic installations can be found in the “IGBT Transistors” category.

Our products come from proven manufacturers. Among our transistor suppliers you will find such brands as: NXP, Hottech, Infineon or Born. Each transistor is checked before being admitted to trading. These steps are taken in order to be sure that the client will receive a qualitative and fully functioning device.
