Also, you can’t run a on 3. Can anyone point my datasheeh Saturation Region” at the bc datasheet: Here is a homemade modified Darlington.

Another question, please if you don’t mind, look at the graphic that says “Figure 4. Jan 6, 3. I think that is here my blank space of knowledge about BJT, could you explain to me a little bit? Assume that the Hfe is 10; not what is shown on the data sheet.

I wrote sinking, but my device will be sourcing, there is a difference?

Ain’t gonna happen if the base resistor R2 is 2. 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. Jan 6, 1. Jan 7, Jan 6, 7. Your name or email address: The resistor is the source of drive voltage fo the fet.

I thought about that, but the pwm wont reach the mosfet will it? Posted by ihaveaquestion in forum: I first choose the typ value of LED forward voltage, 3. The datasheet of says when is sinking 50mA the drop is only about 0.

That should work hey it sims good, right?

I tested with TIP31C using the same method and i got the same result. It is quite marginal at 5V.

To work around, i buy from china, wait months, and get 25 fets for a price of one happy. Jan 6, 2.

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 That was really a surprise, because i used this method 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.

Hello, i having some troubles with a few BJT i am using, it may be a mislearned thing or two that i picked while reading about BJT, so i came to you guys, the circuit is like the follow that i downloaded from the web: This will be used to make the hight current mA go around a timer. The diode is there to let the drive the gate low, to about. Jan 6, 4. Oct 2, 5, 1, Jan 6, 6.

I’ll guide through my process of calculating the dc bias resistors: I see thanks, and about my other doubts? No, create an account now. Yes, my password is: Jan 6, 8. Mar 30, 7, 1, Apr 5, 1. A discussion of Musk’s past success and future plans. Yes, of course i have, this thread datasheeg about what is going on with my transistor calculations, they are wired in parallel, they all have resistors, as i described Apr 24, 7, 1, Do you already have an account?

The image with 15 LED is too big, the circuit is described above datazheet the values are also. Note the current through R2, the current into the base of Q1, and finally, the current through D1 as a function of the simulated output voltage from the I forgot to mention that they are in parallel between collector and Vcc, i thought it was pretty obvious, sorry.

What do you mean get transistor satured so that has a min Vce? You May Also Like: The diode should block it i mean. Quote of the day. Jan 6, 5. I mean difference in the dropout. Help with BJT circuit Posted by in forum: And like i described, that figure it’s just representative, my Vcc is 5v and all the other characteristics are different.
