Field Effect Transistor (FET)

maker

A Field Effect Transistor (FET) is a type of transistor that uses an electric field to control the flow of current.

expanded

FETs are critical components in various electronic devices, utilizing an electric field to regulate current flow between source and drain terminals. They are commonly used in applications requiring high input impedance and low power consumption, such as amplifiers and oscillators, due to their efficient switching capabilities.

examples

The BS170 is an N-channel MOSFET with a threshold voltage of 2V (±0.5V) and a maximum drain current of 500mA.

The BS170 is often utilized in low-power switching circuits and signal amplifiers owing to its efficient voltage control and manageable current handling.

The 2N7000 is an N-channel MOSFET with an on-state resistance of 5Ω and a drain-source breakdown voltage of 60V.

The 2N7000 is typically deployed in digital logic circuits and relay drivers due to its small form factor and robust voltage range.
