IRFP9240 MOSFET. Datasheet pdf. Equivalent
Also note that this amp was built on a breadboard. Likewise, the peak current should also be much lower than the rated maximum.
This eases the design of the bias servo. Commercial use is prohibited without express written authorisation from Mitch Hodges and Rod Elliott. The amplifier can be also used as a sub woofer amplifier but a subwoofer filter stage has to be added before the input stage.
The author Mitch Hodges and editor Rod Elliott grant the reader the right to use this information for personal use only, and further allow that one 1 copy may be made for reference. Make sure you check the idle current before calling the design done! Well, that is the easy route to take for designing an irfp92400 stage.
Further searching revealed a document from Solid State Optronics [ 3 ]where the temperature coefficient for V GS is said to be Many fake lateral MOSFETs are re-badged vertical devices typically HEXFETsso source and drain are in the wrong places and the amp orfp9240 provide close to a dead short across the power supply via the intrinsic body diodes.
This can range anywhere from Ohms up to perhaps 5k. Does output of this circuit is short circuit protected? The R17 must set a current aprox of 1mA, so, we need a r to r. It looks very simple, and includes the class AB driving stage to improve gate driving. I promise it is not hard.

If you are designing a class A amplifier, the first trick see below should be used the second is not needed since the bias is already quite high.
This will show that the threshold voltage falls as T j increases – a negative temperature coefficient. What is not commonly noted is that all MOSFET devices have a fairly high negative temperature coefficient for the gate-source threshold voltage V th. Could the root of this problem be an overheated transistor when soldering? If no, then what should I change in power supply???
For a better understanding, a simplified output stage circuit is shown below.
IRFP – IRFP P-Channel MOSFET Transistor
I use a k pot but when i turn it off i stil have sound in my speakers, a 1M ohm pot would be good or even it will be small? Hi to all someone have the PCB layout for datashewt amplifier? Should V th fall by mV, Iq can only increase by mA.
You may also like: I think that it will do the job, but I want to be sure. Resistors R3 and R2 sets the gain of the amplifier. Thank you very much! It can also cause major problems in switching circuits, but that’s another topic altogether and will not be covered here.
Hi Harry can be used. Thanks for the help. That is why we need to buy a few extra and match them together. Through a lot of time and molten breadboards, I found the best two things to design for are the following:. While this scenario is not common in switching application, if the MOSFET is used linearly it is very real, and has caused problems in the past. While the graph might seem to indicate that the datashset will be greatly exaggerated at lower gate voltages and drain-source current, the initial tests that I did indicate that the effect is roughly similar.
Is good circuit have tested it and it works well the circuit is better for very high voltage.
If heat sink temperature is used for thermal compensation it cannot be used. The resistors seems to be fine.
