Can I replace mosfet with transistor

Answered By: Bryan Peterson Date: created: Aug 03 2021

Remove the base resistor from the circuit because we don’t typically need it anymore with a MOSFET. Connect the gate of the N-MOSFET directly to the activation voltage source. Keep the positive supply connected to one of the load terminals, and connect the other terminal of the load to the drain of the MOSFET.

Can IGBT replace Mosfet

Answered By: Dylan Harris Date: created: Feb 13 2022

Due to the higher usable current density of IGBTs, it can usually handle two to three times more current than a typical MOSFET it replaces. This means that a single IGBT device can replace multiple MOSFETs in parallel operation or any of the super-large single power MOSFETs that are available today.

Quick Answer: What Happens If Mosfet Fails?

How do you test for a bad transistor? Hook the positive lead from the multimeter to the to the BASE (B) of the transistor.Hook the negative meter lead to the EMITTER (E) of the transistor.For an good NPN transistor, the meter should show a voltage drop between 0.45V and 0.9V.If you are testing PNP transistor, you should see “OL” (Over Limit).. How do you protect a Mosfet from a short circuit? The voltage across the internal resistance can be sensed using simple comparator or even a transistor, which switches on at a voltage of around 0.5V.
