The field-effect transistor (FET) is a transistor that uses an electric field to control the shape and hence the electricalconductivity of a channel of one type of charge carrier in a semiconductor material. FETs are also known as unipolar transistors as they involve single-carrier-type operation. The FET has several forms, but all have high input impedance While the conductivity of a non-FET transistor is regulated by the input current  (the emitter to base current) and so has a low input impedance, a FET’s conductivity is regulated by a voltage applied to a terminal (the gate) which is insulated from the device.



We keep stock wide range of FETs of sizes D2PAK, D2PAK-7, DPAK, SO8, SO8(SOP), SOT223, SOT23, SOT363, TSOP-6………
