Jan 7, It is quite marginal at 5V. 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 dataeheet i was passing mA through it’s collector and emitter from a last project.
Yes, my password is: Jan 6, 4. Mar 30, 7, 1, Jan 6, 1.
Hello, i having some troubles with a few BJT i am using, it may be a mislearned thing or two that i picked datasheet reading about BJT, so i came to you guys, the circuit is like datashheet follow that i downloaded from the web: The datasheet of says when is sinking 50mA the drop is only about 0. I’ll guide through my process of calculating the dc bias resistors: I wrote sinking, but my device will be sourcing, there is a difference?
Jan 6, 8. To work around, i buy from china, wait months, and get 25 fets for a price of one happy. And the calcs i showed, why they do not match?
This will be used to make the hight current mA go around a timer. Jan 6, 9. I see thanks, and about my other doubts? The image with 15 LED is too big, the circuit is described above and the values are also. Apr 5, 1. Your name or email address: 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 I first choose the typ value of LED forward voltage, 3.
Jan 6, 2. 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 Jan 6, 5. Another question, please if you don’t mind, look at the graphic that says “Figure 4. Yes, of course i have, this thread is about what is going on with my transistor calculations, they are datashheet in parallel, they all have ief822, as i described I forgot to mention that they are in parallel between collector and Vcc, i thought it was pretty obvious, sorry.
Can anyone point my errors? I tested with TIP31C using the same method and i got the same result. Quote of the day.
Posted by ihaveaquestion in forum: Here is a homemade modified Darlington. And like i described, that figure it’s just representative, my Vcc is 5v and all the other characteristics are different. Assume that the Hfe is 10; not what is shown on the data sheet.
Ain’t gonna happen if the base resistor R2 is 2. Jan 6, 7.
Saturation Region” at the bc datasheet: I think that is here my blank space of knowledge about BJT, could you explain to me a little bit?
