Some of the early concepts for the field effect transistor were outlined in a paper by Lilienfield in 1926, and in another paper by Heil in 1935. There had been many difficulties in realising this type of device and making it work. Field Effect Transistor, FET historyīefore the first FETs were introduced into the electronic components market, the concept of these semiconductor devices had been known for a number of years. If bipolar technology was used the power consumption would be orders of magnitude greater and the power generated far too large to dissipate from the integrated circuit.Īpart from being used in integrated circuits, discrete versions of these semiconductor devices are available both as leaded electronic components and also as surface mount devices. This enables the very large scale integrated circuits to operate. In this application FET circuits consume much lower levels of power than ICs using bipolar transistor technology. However the major use for the field effect transistor, FET is within integrated circuits. The FET used in many circuits constructed from discrete electronic components in areas from RF technology to power control and electronic switching to general amplification. The field effect transistor, FET is a key electronic component using within many areas of the electronics industry. The Field Effect Transistor, FET, is a three terminal active device that uses an electric field to control the current flow and it has a high input impedance which is useful in many circuits.įET basics FET specifications JFET MOSFET Dual gate MOSFET Power MOSFET MESFET / GaAs FET HEMT & PHEMT FinFET technology IGBT Silicon carbide, SiC MOSFET GaN FET / HEMT What is a FET: Field Effect Transistor: Types, Technology.
