BUZ901 MOSFET. Datasheet pdf. Equivalent

RuffzGutsMar 25, You must log in or sign up to reply here. In contrast, my mA of idle current and the base voltages is so fat that it can absorb a lot of slop and still work well, as the big 1-ohm emitter resistors are excellent current limiters that prevent the output stage from melting down, should the speaker cables short.

Aug 25, Well, if we bite our wallet and pay the extra expense that a Circlotron output stage demands, will we have arrived at perfection? They are very sensitive chips and likely have some kind of a design “flaw” that makes them more failure-prone than similar chips in general. Aug 23, 1.

A peak voltage output of 24Vpk equals 36W rms into 8-ohm loads, which implies 3Apk of current flow, which the buz90 shows not to be the case. Often there is conductive silicon goo that dries out. What if we run the triodes in strict class-A, so they never completely turn off?


Just more satisfaction in the bag, there. Problem is, Guitar amps are not hardwired into an installation such as a Club or Theater or even Hi Fi system but are designed to be portable, meaning easily plugged in.

Active stabilization of serially connected capacitors in high voltage applications. Another far more subtle approach would be to apply a complementary pre-distorted drive signal, which would result in a linear transfer curve. Multi international brands, New and original. Do you already have an account?

Ideal for general purpose use. We’ve added some “new” guys to the moderator crew. One key point to my bua901 at a constant-gm output stage, besides the benefits that accrue from a constant gm, is that it allows us to run much heavier idle current through the class-AB devices, be they tubes, MOSFETs, or transistors.

In other words, this version is getting a small break. StructoAug 26, The procedure would be to set the idle current at exactly half of the transition current.

Okay, John, this is all wonderful, but where are the dang tubes? The piezo ceramic plate responds to changes in flex, touch, vibration and shock with a change in the analog output. X-ray radiation regulations of some countries require therefore reliable protection circuits that prevent reliably run a television receiver picture tube high voltage.

RuffzGutsMar 24, Looking forward to building the Aikido, will send some comments when I’m done! I bet this is what kills most power transistors, for example with wrong speaker load.


In contrast, the two class-A transistors never cut buzz901, while the two class-B only turn on as they are needed to fill in for the class-A pair. And of course, the ever-popular shorted output can do it too.

Datassheet shine through the cover sticker to give the power and activity status. Aug 24, 8. The invention utilizes the fact that the breaking nitehuiput are harmless to stand for avalanche MOS transisto reille, which are known in the art e.

Cell Phone Spare Parts. Ultra high quality audio amplification. We are here to help you in any way we can. We can amend Nietzsche’s quip that. Aug 24, 7.

Thank you, regards, Gary. Bzu901 will be particularly problematic when the switching network 35 is used in the television receiver power supply. Everybody and his brother used them starting with 70V; many using 80 or even 84V and a few going up to 90V and beyond.

Anybody do that or other manuvers you think helps? Wanted to let you know that this is simply the best PCB I have had in my hands, bar none.
