JFET Characteristic for VGS = 0 V and 0Holes injected to Source (S) through p-type channel and flowed to Drain (D).

Current flow : from Source (S) to Drain (D).

Major structure is p-type material (channel) between embedded n-type materialto form 2 p-n junction.

Because the resistance of the channel depends on the gate-to-source voltage (VGS), the drain current (ID) is controlled by that voltage.

Current flows into the Drain (D), through the channel, and out of the Source (S)

In the normal operation of an n-channel device, the Drain (D) is positive with respect to the Source (S).

Major structure is n-type material (channel) between embedded p-type materialto form 2 p-n junction.Usually used as an Amplifier and logic switchĭrain Drain Gate Gate Source Source SYMBOLS n-channel JFET p-channel JFET.

FET is unipolar – uses only one type of current carrier.BJT is bipolar – conduction is done by hole and electron both.Can be fabricated with fewer processing.
