Is it better to have a higher VGs than VDS on a MOSFET?

Is it better to have a higher VGs than VDS on a MOSFET?

Vds then responds accordingly and as the MOSFET turns on more and more, Vds decreases. At some point, Vds decreases below the Vgs you are applying. If you continue to drive the Vgs higher and higher the MOSFET continues to turn on more and more and Vds continues to decrease to the point where the MOSFET cannot conduct any more current through it.

What happens if you increase your VGS to the point of VGSs?

If you start increasing your Vgs to the point of Vgss, well…cops show up and shut you down. Underage drinking, drug use etc.. You go to jail (Your transistor has been damaged). Thanks for contributing an answer to Electrical Engineering Stack Exchange!

Is the RDS always measured at a specified VGS?

Rds (on) is always measured at a specified Vgs. For example, it might be 77m Ω with Vgs = 10V and Id = 17A and Tj = 25°C. That 10V is the Vgs you need to feed your MOSFET for it to be happily turned on so it looks like a very low resistance.

What’s the difference between VGs and VGS of 77m?

For example, it might be 77m with Vgs = 10V and Id = 17A and Tj = 25°C. That 10V is the Vgs you need to feed your MOSFET for it to be happily turned on so it looks like a very low resistance. Vgs also comes up when you want to know the gate leakage. Igss might be +/-100nA at Vgs = +/-20V and Tj = 25°C.

Which is the voltage across the drain terminals of a MOSFET?

Vds is the voltage across the source-drain terminals of the MOSFET. It is not your supply voltage. You then apply a voltage across the gate-source terminals of the MOSFET.

How to analyze MOSFET circuit with d.c.sources?

To analyze MOSFET circuit with D.C. sources, we mustfollow these five steps: 1. ASSUME an operating mode 2. ENFORCE the equality conditions of that mode. 3. ANALYZE the circuit with the enforced conditions. 4. CHECK the inequality conditions of the mode for consistency with original assumption.
