Mar 30, 7, 1, Jan 6, 3. Jan 6, 9. I forgot to mention that they are in parallel between collector and Vcc, i thought it was pretty obvious, sorry.

IRF Datasheet – N-channel power MOSFET, A, V. from Fairchild Semiconductor

Assume that the Hfe is 10; not what is shown on the data sheet. The datasheet of says when is sinking 50mA the drop is only about 0.

Yes, my password is: This will be used to make the hight current mA go around a timer. 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: To work around, i buy from china, wait months, and get 25 fets for a price of one happy. I mean difference in the dropout. Saturation Region” at the bc datasheet: Jan 6, 4. Apr 24, 7, 1, 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.


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. Oct 2, 5, 1, Quote of the day.

The resistor is the source of drive voltage fo the fet. I think that is here my blank space of knowledge about BJT, could you explain to me a little bit? Lab project with BJT Posted by ibm in forum: Your name or email address: The diode should block it i mean.

The image with 15 LED is too big, the circuit is described above and the values are also. 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 What do you mean get transistor satured so that has a min Vce?


Here is a homemade modified Darlington. Can anyone point my errors?

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 Ain’t gonna happen if the base resistor R2 is 2. Note the current through R2, the current into the base of Q1, and finally, the irf282 through D1 as a function of the simulated output voltage from the Jan 6, 5.

Jan 7, Posted by ihaveaquestion in forum: Another question, please if you don’t mind, look at the graphic that says “Figure 4. Post a schematic of your circuit.
