Saturation Region” at the bc datasheet: Quote of the day. Lab project with BJT Posted by ibm in forum: 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 The datasheet of says when is sinking 50mA the drop is only about 0.

Jan 6, 1. Jan 6, 4. Jan 6, 8.

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.


Your name or email address: Jan 6, 3. Oct 2, 5, 1, Another question, please if you don’t mind, look at the graphic that says “Figure 4.

I mean difference in the dropout. Jan 6, 5. That should work hey it sims good, right?

Post a schematic of your circuit. Help with BJT circuit Posted by in forum: 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 Assume that the Hfe is 10; not what is shown on the data sheet.

Apr 24, 7, 1, It is quite marginal at 5V. Can anyone point my errors?

Jan 6, 7. 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. Do you already have an account? Jan 6, 6. The diode is there to let the drive the gate low, to about. You May Also Like: Also, you can’t run a on 3. And the calcs i showed, daatsheet they do not match?


I forgot to mention that they are in parallel between collector and Vcc, i thought it was pretty obvious, sorry. Posted by ihaveaquestion in forum: The resistor is the source of drive voltage fo the fet.

Ain’t gonna happen if the base resistor R2 is 2. I’ll guide through my process of calculating the dc bias resistors: No, create an account now.

To work around, i buy from china, wait months, and get 25 fets for a price of one happy. Apr 5, 1. I wrote sinking, but my device will be sourcing, there is a difference?

I first choose the typ value of LED forward voltage, 3. Jan 6, 2.
