irf3205, FET, MOSFET power FET works with words, is the "drain - gate-source flowing through the channel ID, to reverse bias pn junction between the gate and the channel formed Voltage Control ID ". More correctly irfp150 FET, flows through the passage width ID, i.e. a channel cross-sectional area, it is reverse-biased junction changes from pn, generating depletion layer is expanded variation control reasons. In the non-saturation region VGS = 0, represents an extension of the transition layer is not large because, according to the drain - VDS applied between the source electrode of an electric field, some of the electrons of the source region is a drain got me FET, i.e. from the drain to source a current ID flows. From the gate to drain excessive expansion layer constitutes a part of the channel blockage FET irf1010e, ID saturation. This state is called the pinch-off. This means that the transition layer of the channel portion of the barrier, not a current is interrupted. irf640n 12n60 FET, FET, power MOSFET 1. The role of FET can be used to enlarge. Because of the high input impedance of the FET amplifier, therefore the coupling capacitor can be smaller capacity, without the use of an electrolytic capacitor. 2. FET high impedance input impedance is very suitable for conversion. Commonly used in the multi-stage amplifier input stage for impedance transformation. 3. FET can be used as a variable resistor. The FET can be conveniently used as a constant current source. 5. FET can be used as an electronic switch. 12n60 FET, are fertile Electronics (certified), FET provided by the Dongguan City is Wal-Electronic Technology Co., Ltd.
