IRFP – IRFP part cross-reference datasheet –
Dec 26, 2, Do you mean this, rated at 5. 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. Even with a source resistor dropping several volts, the drain current accuracy for a fixed gate voltage at such a low level would be poor. The gate voltage would need individual adjustment for accurate drain current setting.

Jan 13, 7. Jan 13, 8. Dec 20, 10, 1, The datasheet for every Mosfet shows a wide range of gate-source voltages to turn it on. Your old Mosfet is guaranteed to turn on very well with a gate-source voltage of 10V.
The SIM program shows only a “typical” Mosfet but you cannot buy a “typical” one, you might get one that is much less sensitive.
But maybe your teacher does not know DAT. Jan 13, 9. So the only thing we need to change in this circuit is to increase the value of a constant current datashdet. And of datasjeet you could use this circuit to plot the transfer characteristics. Jan 13, 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.
I am a teacher of math and i am interesting in design many types of oscillators theoretically then practically.
At this times i’m on my final stages on my last chapter of designing mixers ;so please please try to help me when i’ll facing difficult practices. I once had to bias some quite large FETs at a tiny fraction of their rated drain current.
This was done as follows: A substantial source resistor was used, to drop a couple of volts. A select-on-test resistor was chosen to set the gate voltage as required for each circuit individually.
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. They worked for many years without failing. I do not think datawheet this would have stood any chance of working properly without the big source resistors.

Datashee need for your feedback and also for you Mr. Isn’t the IRL one of the oldest and poorest Mosfets ever made?
Really i do not know the history of this partsorry. Then most logic ICs cannot turn them on with only 3. ALL Mosfets have an avalanche diode zener diode from drain to source due to the physical way they are made. But the gate-source max allowed voltage is only 20V for most Mosfets and if exceeded then the Mosfet will be blown up.
Some “logic-level” Mosfets have a max allowed gate-source daasheet of only 10V. If you don’t know how to read datasheets then maybe you should do datasyeet instead. I know i got a weak english learning in my home but that not mean no one could not understand what i have written.
So if you had read this thread from the first time thus you will understand. Why did not asked your self why Mr. Jony can read and understand what i am writing? Hence no need to hints on my English sir To Audioguru: I do not like to speak with you my son and be polite and respecting the people is the first step to deal with them BYE.
