Some “logic-level” Mosfets have a max allowed gate-source voltage of only 10V.
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.
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. What irf;140 happen to it if the FCC repeals “net neutrality” regulations?

The datasheet for every Mosfet shows a wide range of gate-source voltages to turn it on. Jan 12, 1. The SIM program shows only a “typical” Mosfet but you cannot buy a “typical” one, you might get one that is much less sensitive.
A substantial source resistor was used, to drop a couple of volts. And of course you could use this circuit to plot the transfer characteristics. Posted by alitaban in forum: Your old Mosfet is guaranteed to turn on very well with a gate-source voltage of 10V. The gate voltage would need individual adjustment for accurate drain current setting. Best antivirus for professional Posted by aamirali in forum: Jan 12, 9 0. Do you already have an account? 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.
Jan 13, 8. Arduino Zero Arrives June 15th The beloved platform announces a new model set to arrive on June 15th. I am a teacher of math and i am interesting in design many types of oscillators theoretically then practically.
If you don’t know how to read datasheets then maybe you should do gardening instead. But the gate-source max allowed voltage is only 20V for most Mosfets and if exceeded then the Mosfet will be blown up. Dec datashest, 2, No, create an account now. Jan 12, 2.
The IoT was largely built during a period of guaranteed equal access to connectivity. Jan 13, 9. Jan 12, 3. Quote of the day.
ALL Mosfets have an avalanche diode zener diode from drain to source due to the physical way they are made. Jan 13, Really i do not know the history of this partsorry. Even with a source resistor dropping several volts, the drain current accuracy for a fixed gate datassheet at such a low level would be poor.
Feb 17, 4, 1, They worked for many years without failing. 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. Yes, my password is: Dec 20, 10, 1, Hence no need to hints on my English sir To Audioguru: So if you had read this thread from the first time thus you will understand. Discussion in ‘ General Electronics Chat ‘ started by vcoasmJan 12, Do you mean this, rated at 5. A select-on-test resistor was chosen irp140 set the gate voltage as required for krfp140 circuit individually.
So only real measurement can give you exact K value.
IRFP 140 N
Why did not asked your self why Mr. Try use this equation: I once had to bias some quite large FETs at a tiny fraction of their rated drain current. Jan 13, 7. Your name or email address: Jan 12, 4.
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 the only thing we need to change in this circuit is to increase the value of a constant current source. Bootstrap instead of any driver for mosfet Posted by rabiuls in forum: I need for your feedback and also for you Mr.
Isn’t the Datqsheet one of the oldest and poorest Mosfets ever made? This was done as follows:
