I mean difference in the dropout. The diode is there to let the drive the gate low, to about.

IRF – Fairchild Semiconductor Datasheet PDF – DataSheetBank

What do you mean get transistor satured so that has a min Vce? And like i described, that figure it’s just representative, my Vcc is 5v and all the other characteristics are different.


The datasheet of says when is sinking 50mA the drop is only about 0. First i pick the transistor, for the first time i chose BC, i took a look at it’s datasheet and followed the same process i did last time when i was passing mA through it’s collector and emitter from a last project. It is quite marginal at 5V. Assume that the Hfe is 10; not what is shown on the data sheet. Jan 7, The image with 15 LED is too big, the circuit is described above and the values are also.

I thought about that, but the pwm wont reach the mosfet will it? This is not about the circuit itself, it’s about what kinda o mistake i’m making while calculating the collector current and the base current to the BC IRF Can i run this “thing” i am trying to do with it?

Jan 6, 4. I first choose the typ value of LED forward voltage, 3. That was really a surprise, because i used this datahseet 3 times, in three different projects and it worked everytime, it maaaay be a really nice coincidence of values, but i want to know where is my mistake.

And the calcs i showed, why they do not match? Here is a homemade modified Darlington. Yes, my password is: I forgot to mention that they are in parallel between collector dwtasheet Vcc, i thought it was pretty obvious, sorry.

Jan 6, 9. I tested with TIP31C using the same method and i got the same result. Oct 2, 5, 1, I see thanks, and about my other doubts?

You May Also Like: Yes, of course i have, this thread is about what is going on with my transistor calculations, they are wired in parallel, they all have resistors, as i described Can anyone point my errors? I think that lrf822 here my blank space of knowledge about BJT, could you explain to me a little bit?
