irf540n MOS tube, to-263, SMD FET, the advantages of using a power MOSFET: FET is a voltage-controlled device MOS tube IRF3710, and the transistor is a current control element. FET at only allowed to take less current situation from the signal source MOS transistor IRFP450, should be used FET; and in low signal voltage MOS transistor 5n60c, has permission to take more current from the signal source conditions, should selection transistors. FET is the use of majority carrier conduction, so called unipolar device, and both transistors are the majority carriers, but also the use of minority carrier conduction, called bipolar devices. fqpf8n60c, each application characteristics FET, MOSFET, Fairchild FET and the FET transistor 1. The source electrode s, a gate g, a drain d respectively correspond to the transistor emitter e, base b, set electrode c, their role is similar. 2. FET is a voltage-controlled current devices controlled by vGS iD, its amplification factor gm is generally small, and therefore the ability of poor amplification FET; transistor is current controlled device, by iB (or iE) control iC. 3. FET gate FET hardly take the current (ig ?0); and the transistor base work always draw a certain current. Thus FET gate input resistance is higher than the input resistance of the transistor.
