Described as active solid-state electronic devices, field effect transistors feature a U-shaped or rounded metal with three connection wires that allow us to use electric current from one source to create another electrical signal. The term "transistor" is actually short for "transfer resistor," meaning that electricity is transferred from an input signal to an output signal. Sound amplifiers, electrical switches and radios are the most common examples of a field effect transistor (FET).

The field effect transistor has different forms, including the metal oxide semiconductor field effect transistor, or the metal semiconductor field effect transistor. The MOS field effect transistor contains an insulated silicon dioxide layer. Its characteristics include low frequencies and high noise levels. A metal semiconductor field effect transistor is used in microwave integrated circuits or in low-noise amplifiers. Variations of the field effect transistor include an organic field effect transistor, an ion sensitive field effect transistor and a nanotube field effect transistor. When creating or distributing field effect transistors for your company, note that:

1. Field effect transistors manufacturers should be certified.

2. Accessories and replacement parts for field effect transistors should be in stock.

3. Some manufacturers customize field effect transistors to meet customer needs and demands.

Tips & Tactics

Helpful advice for making the most of this Guide

• Organic field effect transistors are made from organic semiconductor molecules instead of silicon. They can be produced at lower temperatures, and they are compatible with plastics.
• Known as a chemical sensor, the ion sensitive field effect transistor measures the pH levels in solutions related to environmental applications, while the nanotube field effect transistor conducts well with graphite or with polymers.
