MOSFETs… yes, they have so many gate voltage threshold parameters. How do you navigate them if you, say, want to be able to control a MOSFET with a 5 V signal? Here’s how.

  • Look for “drive voltage” as this is indicative of how.

  • “Gate threshold voltage” is the minimum voltage that you’ll barely get any MOSFET switching behavior.

  • Max gate voltage is, of course, the maximum voltage you can put on the gate.

MOSFETs are kind of like BJT transistors, they’re not perfect binary switches. When there is less voltage, the source-drain path is more restrictive to the flow of current than when there is more. That’s what the range of gate threshold voltages is indicative of, and the restrictiveness to current flow is indicated by the varying resistance between the source and the drain.
