# Transistor
|
|
Semiconductor electronic component, used for switching and current amplification. Also considered one of the most important inventions, since
|
|
it is superior to its predecesor, i.e. vacuum tubes, which are bulky, inefficient (a lot of heat dissipation), have high current consumption
|
|
and high unreliability for fast switching applications (such as digital circuits).
|
|
|
|
The invention of the transistor (at Bell Labs) made faster, cheaper, more reliable and smaller computers possible, including the invention
|
|
of integrated circuits.

## Bipolar transistors (BJT)
|
|
BJTs are current controlled.
