You May Also Like: Some “logic-level” Mosfets have a max allowed gate-source voltage of only 10V. However, these devices are also have max.
If you want to drive a FET with only 3. Feb 17, 4, 1, Best antivirus for professional Posted by aamirali in forum: That’s unlikely to be a useful amount of current in your application, and is certainly not in any way the fully on state of the MOSFET.
So how can 3. Read your own question. Sign up using Email and Password. Yes, my password is: I need for your feedback and also for you Mr. These all have a gate threshold of about 1. Jan 13, 8.

Quote of the day. Jan 12, 5. Why did not asked your self why Mr. You should also look more closely at what gate threshold really means.

The answer is obvious since it is embodied in the question. If you don’t know how to read datasheets then maybe you should do gardening instead.

So if you had read this thread from the first time thus you will understand. I know i got a weak english learning in my home but that not mean no one could not understand what i have written.
Gate threshold is not a useful parameter if you want to turn the FET fully on. Discussion in ‘ General Electronics Chat ‘ started by vcoasmJan 12, They aren’t making any promises what happens between the threshold voltage and 10 V.
I guess I misunderstood the meaning of the phrase gate threshold According to it’s datasheet, the “Gate to Threshold Voltage” is V No, create an account now. Jan 13, So one of those can be usefully driven from 3. Jony can read and understand what i am writing? Try use this equation: I was aware at the time that what I was doing was pretty kludgey, but it was carefully done, and the horrid little circuits did what they were required to do.
Your old Mosfet is guaranteed to turn on very well with a gate-source voltage of 10V. Hence no need to hints on my English sir To Audioguru: I am a teacher of math and i am interesting in design many types of oscillators theoretically then practically. Then most logic ICs cannot turn them on with only 3. Different samples of the same device are likely to behave radically differently at the sort of small gate voltage required, so that some may be barely on at all, others will conduct too much.
Dear Jony Senior Member ; I would like to think you very much and i hope you help me next time to continue my practicals circuits to finalizing my book. The drain to source on-resistance is much more relevant, just a few lines in the datasheet below the threshold voltage.
The gate voltage would need individual adjustment for accurate drain current setting. Posted by alitaban in forum: Jan 12, 1. Really i do not know the history of this partsorry.
