Welche Arten von MOSFET Transistoren gibt es?
Der MOS-FET ist auch als IG-FET bekannt. Diese Bezeichnung kommt von Insulated Gate und bedeutet isoliertes Gate. Das hängt mit dem Aufbau des MOS-FET zusammen. Es gibt insgesamt 4 MOS-FET-Typen, wobei man zwischen n-Kanal- und p-Kanal- sowie Anreicherungstyp und Verarmungstyp unterscheidet.
Wann geht ein MOSFET kaputt?
Das passiert, wenn die Bauteile zu feucht gelagert wurden, und Wasser ziehen, beim Löten geht dann das Gehäuse kaputt und möglicherweise ein Pin auf.
How does a MOSFET transistor work?
The MOSFET works by electronically varying the width of a channel along which charge carriers flow (electrons or holes). The charge carriers enter the channel at source and exit via the drain. The width of the channel is controlled by the voltage on an electrode is called gate which is located between source and drain.
How is MOSFET different from BJT?
The main difference between BJT and MOSFET transistors are discussed below. The BJT is a bipolar junction transistor whereas MOSFET is a metal oxide semiconductor field effect transistor. A BJT has three terminals namely base, emitter and collector, while a MOSFET has three terminals namely source, drain and gate.
How to use MOSFET?
To use a MOSFET as a switch, you have to have its gate voltage (Vgs) higher than the source. If you connect the gate to the source (Vgs=0) it is turned off. For example we have a IRFZ44N which is a “standard” MOSFET and only turns on when Vgs=10V – 20V. But usually we try not to push it too hard so 10V-15V is common for Vgs for this type of MOSFET.
What is v DD of a MOSFET transistor?
V DD of a MOSFET transistor is the DC voltage that is supplied to the drain of the transistor . It is a very important voltage when biasing the transistor because it determines how much the AC signal can be amplified to in the transistor.
