fqp13n50c, FET IRFZ48N FET COMPARATIVE Fairchild MOSFET FET and bipolar transistors: FET is a voltage control device, the gate does not substantially take current, and the transistor is a current controlled device, the base must be removed a constant current. Thus, in a very small source rated current situation, should use FET. FET is a multi-conducting, and both carriers are involved in the transistor conductive. Since the concentration of minority carriers on the temperature, radiation, etc. are sensitive to external conditions IRF840 FET, and therefore, a large case for environmental changes, the use of more appropriate FET. In addition to the same FET transistor can be used as an amplifier parts and controllable switch, it can also make use of voltage-controlled variable linear resistor. FET's source and drain are symmetrical in structure, can be used interchangeably, depletion type MOS transistor of the gate - source voltage can be positive or negative. Therefore, the use of flexible than FET transistor. irfp260N, FET FET, AC power MOSFET parameter exchange parameters can be divided into low-frequency output resistance and transconductance two parameters, the output resistance is generally between tens of thousands to hundreds of thousands of Euro in Europe, while the low-frequency transconductance general within a few tenths to a few milli-west range, special up to 100mS, or even higher. Low-frequency transconductance gm it is to describe the gate, drain-source voltage control action current. Capacitances of the FET capacitance between the three electrodes, it is smaller the value the better the performance of the tube.
