Questions about including mosfet models in design 1. Thanks for looking up this link too BTW. This is then substituted for the switching time and a convenient formula results: Synthesized tuning, Part 2: PNP transistor not working 2. It is best to have this divider powered from a regulated voltage, such as a Zener diode, instead of the 28V. Allowing more current to drive the gate, i.

You could easily switch the output to “0” V in software. Now, assuming that Rdson is about 0. Turn on power triac – proposed circuit analysis 0. The circuit is simple too How can the power dissipation be calculated for the FET so I can properly heat sink it?


So, you can use a 2. BTW, MrCal, your analysis above was excellent.

Could it be the 2. OK, I see that it’s 24V at about 11A. I also tried a few with a ratio – e. OK, so the circuit appears to work.

So, try simulating the circuit with the two resistors and the diode and see what happens.

Now, you cannot just remove parts without knowing what you are doing. Enjoy your design workk!

BTW, you’ve made this discussion much more interesting than i thought it would ever become: Part and Inventory Search. Any suggestions links to schematics?

Two questions regarding LL mosfets that I have are 1. That’s cool, that was my major too, way back when. I also agree that the static power should 1rfzz44n checked out more carefully too, as you nicely outlined above. Choosing IC with EN signal 2. Dec 242: Alas, I do not have a scope: This mean that it is typical between 2V and 4V.

Maybe I should just scrap the switching idea and add parallel BPT’s to the regulator. One thing I love about EE is that there is always something new to learn and its fun sharing what you learn with others. Hope this helps, VVV. Post as a guest Name. Also, because of this unique application, it will be possible to drive two MOSFETs of the type previously discussed with one single channel driver chip, thus allowing ma per NMOS, which is rather good for this app dont you think?

Has anyone tried somthing similar?
