  • Do MOSFETs have voltage drop across source and drain when turned on?
    The equivalent resistor might be tens of ohms for a small MOSFET down to milliohms for a large power MOSFET From the 2N7000 datasheet you can see that for a gate voltage of 4V and a Vds < 0 5V the resistance is a couple of ohms (typical, worst case would be much more than that)
  • mosfet - In an NMOS, does current flow from source to drain or vice . . .
    Conventional current flows from Drain to Source in an N Channel MOSFET The arrow shows body diode direction in a MOSFET with a parasitic diode between source and drain via the substrate This diode is missing in silicon on sapphire 2a is a JFet so different topology 2d is a MOSFET with no body diode I've never seen one
  • transistors - Understanding the curves of a MOSFET - Electrical . . .
    I am trying to understand the curves of a MOSFET Sorry if the question is very basic Where the red point is is the saturation zone of the MOSFET, therefore the source drain voltage must be 0V because at this point the MOSFET is saturated conduction at maximum current, because on the X axis of the graph called Vds marks 10V for the red point
  • Transconductance of a MOSFET - Electrical Engineering Stack Exchange
    Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
  • Question about the basic differences between a MOSFET and a FET
    MOSFET = Metal Oxide Semiconductor Field Effect Transistor Regardless of what the gate material is, the term is important because it tells you some important hings about the nature of the transistor A MOSFET, as opposed to some other types of FET which may have some but not all of these attributes
  • mosfet - High side driver and Low side driver - Electrical Engineering . . .
    Since the gate of the MOSFET has to be V\$_{GS}\$ volts higher than the source, a special IC is needed to translate the logic level at the CTL lead into the much higher gate voltage Even if the N-channel was being used in a low-side configuration, the driver chip would be needed to properly drive the gate fast enough
  • mosfet - Vdss, Vds(max), BVdss and Vgss, Vgs(max) - Electrical . . .
    It seems that unfortunately different manufacturers use slightly different notation Usually V_DSS or V_DS(max) are the maximum allowable Drain-Source voltage according to manufacturer datasheet, the same for V_GS(max) but for Gate-Source voltage
  • When is a MOSFET more appropriate as a switch than a BJT?
    \$\begingroup\$ Going back decades, when MOSFETs were still new devices, I remember seeing one article where a MOSFET manufacturer pointed out that they'd made a real accomplishment, to show the parts were really coming on: They'd built and were shipping the VN10KM, that was specifically designed and intended to fit in the usual ecological niche currently occupied by the venerable 2N2222
  • What is the difference between MOSFET transistor and normal transistor . . .
    [From Question]: MOSFET transistor and normal transistor A MOSFET is a normal transistor - it's a Metal-Oxide-Semiconductor Field-Effect Transistor A BJT is another normal transistor - a Bipolar Junction Transistor The question itself doesn't make much sense in that regard But lets assume for now you mean BJT when you say "normal"
  • mosfet - How to design the gate resistor value? - Electrical . . .
    This is the datasheet of the driver IC I am working on (LM5112) Following is the application diagram of the module Basically this is the GATE driver circuit for the MOSFET with PDM signal as the
