Metal-Oxide-Semiconductor Field-Effect Transistor, a type of field-effect transistor (FET). MOSFETs have an insulated gate, the voltage of which determines the conductivity of the device. This can be used for amplifying or switching electronic signals. (From: Wikipedia)

Is this driver/FET combination wrong?
Your output voltage will be 5V_IN-Vgs(th) of your MOSFET.
Yes, a P-FET would be very suitable for this application. …

Is an IGBT comprised of many micro sized transistors, or is it just a single device in itself?
This isn't a complete answer to your question, but too much of an answer for a comment.
I don't know enough about semiconductor manufacturing to tell if a single die (macroscopic level) actually has m …

LED Matrix Constant Current Driver with MOSFET and NPN Trans
If you have the space available and can afford the almost free resistors, this is one way of making sure to have both current balance between the strings and minimize the increased current in adjacent …

Placing MOSFET heatsink on PCB?
Opposite side of PCB will be limited by the via thermal resistance. You can use for example Saturn PCB calculator to estimate the resistance. It will take a lot of them. Check the via rules for your P …

High voltage supply MOSFET inverter
Many possible ways to make it happen. Here is one with only discrete components:
The downside is that it will consume a few mA of current as long as the battery is connected.

Analog switch unpowered state
There are special analog switches for the very purpose. TI calls them FET bus switch.
If you take a look at your MAX4737, it specifies analog voltage up to your Vcc, i.e. clamping your analog voltage …

Can I Exceed a N Channel MOSFET's -Vgs Rating When Using It as a High Side Switch
No, you will break down the gate oxide layer. If you’re lucky, it may take years. Absolute max ratings are there for a reason. Don’t exceed them.

Why is my inverter circuit outputting this waveform?
Your high side MOSFETs are N-channel, so you need gate voltages above 12 V to turn them on. Presently, your opamp which drives them are driven from the same 12 V rail so they can't turn on.
Either you …

I am so confused about lighting electronic matches with altimeter
Your 9 V battery has too high internal resistance to supply 5 A at 8.4 V. From the datasheet, it has about 3 Ω, so with a short circuit you get about 3 A max (and no voltage). To have 5 A at 8.4 V, yo …

Is it better to use a NTC or a MOSFET to limit inrush current
Here is one crude way to do it:
simulate this circuit – Schematic created using CircuitLab
The ICL (NTC-resistor, here 10 Ω cold resistance) is a nice way to limit inrush, but will suffer voltage d …

DCM vs CCM Noise Spectrum
Here is a really quick and dirty simulation for you. Several downsides: no filters what so ever and would not transfer the same amount of power. Just the top switch waveform difference.

Single-phase voltage inverter
You need to change your V3, V4 gate drive signals to connect between source and gate. By grounding them, you make a very strange circuit.

Why is IRFZ44N MOSFET with ESP 8266 always closed?
You need either a MOSFET driver (or some level sifter) or a MOSFET with lower Vgs(th). Your gate voltage from your ESP needs to be significantly higher than the rated Vgs(th) of the MOSFET. …

Why does a MOSFET cause a PAM8403 amplifier board to rapidly reset, and how can I fix it?
If you do need to having to switch off an IC, do it on the high side with a P-channel MOSFET and pay attention to any exposed inputs which may still receive voltage higher than ground which may need attention …
