Mosfet vs transistor

PWM motor drive, when should one use a FET over a normal transistor? Had I though this thru, knowing the low resistance of the MOSFET vs transistor, I can understand why this is true. Using MOSFETs versus Darlington Transistors. When is a MOSFET more appropriate as a switch. CachadLiknandeÖversätt den här sidanapr.

BJTs are much more suitable than MOSFETs for driving low-power. A consumed in the base of the transistor controlling it. You will find that the voltage across the MOSFET when on will be lower than the V c e . Usually BJTs have also a lower threshold (around V vs 1+ V for the MOS). But generally speaking, a transistor (BJT or FET) is a complex .

How to use an N channel MOSFET (a type of transistor) to turn anything on and off! An ordinary NPN transistor will turn ON when the base voltage is about 0. MOSFET needs the gate terminal to be at least 2v to 5v, . Transistor Tutorial and Summary about Bipolar Transistors and Field Effect. When no voltage is applied to the gate of an enhancement FET the transistor is in the “OFF” state similar to an “open switch”. En FET-transistor är en transistor där strömmen mellan drain och source styrs kapacitivt från styrelektroden (gate) genom fälteffekten.

Because bipolar-transistor gain rises with temperature and reduces the VBE component of VCE(sat), the rise in bipolar RCE(sat) is generally . And what is the n-channel (?) MOSFET doing?
