Started by fastline Yesterday datasgeet 8: Thread starter breadboardguy Start date Jul 22, I’ve seen circuit where they place it between the drain and source of each transistor, will it do the job?

IRF511 Datasheet

I can state that it is a fact that there are many power converters out there that do not use an ‘extra’ diode in parallel with the MOSFET, and depend entirely on the integral body diode to take care of the back emf of any inductive loads.

Hi, I can add a little information here Articles Top Articles Search resources. Sure, many people get away with it, but why take the chance when a simple schottkey is much better at the job anyway. Secondary usually is the reverse recovery, which can be longer than an external carefully located high speed diode.

Will i be fine to use only the irf on my robot? I’m sure many people think that’s why they are there, just from looking at the datasheets.

Just saying hello Started by MichaelaJoy Yesterday at 6: Right on the motor if you can. For a better experience, please enable JavaScript in your browser before proceeding. I need to build a h-bridge for my mobile breadboard aka hammerhead cause of its shape. Some good simulations might tell what is best to do with a given application, and some prototype measurements would also help. You must log in or register to reply here. Also place a pF ceramic cap between the drain and source of all the mosfets.


I blame lack of coffee. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. They are incredibly enlightening. Place datasjeet freewheel diode as close to the motor as possible. The bottom line is that whether or not you can use the integral body diode depends on the application, in how much power that diode will have to dissipate. As a quick example of an application that does not require an extra diode, consider a relay driver where the relay turns on and off once per hour.

However, i have a geometry question that is burning my lips but i only see my father in two days This is probably the biggest factor in determining if you can use the internal diode or not. By freewheel diode, do you irf11 fly back dafasheet

That is probably just something added by the creator of that web page. Sorry, was braindead on the diode.

Replacing a 4 pin leaded inductor with a 2 pin Started by ir511 Yesterday at Nope the man that quoted it on his web site is right it tells in the data sheet read it’s on the first page here a quote. Forums New posts Search forums. Yes, but it says nothing about using it for inductive loads.

Potentiometer Questions Started by norbss Yesterday at I have doubts that it is a more practical way of doing with npn and pnp combo I also need to know dayasheet to place the flyback diode please. That just seems silly to me. On the other hand, a very high speed H bridge may benefit from adding extra diodes because doing that, if not anything else, moves some of the heat out of the transistor package and therefore keeps it cooler. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb Media New media New comments Search media.

Datasgeet dose say It has source to drain eatasheet built in for inductive loads. As a final note, we’d also have to look at the effect of the negative voltage on the drain when the diode conducts, which might force us to have to use a gate datasjeet signal that actually goes a little negative rather than to zero as many designs do N-MOSFET application.

If the application can stand the extra loss in power and the device itself wont overheat, then there is no reason not to use the internal diode.

krf511 On the other hand, if the device xatasheet or has to be used in high heat environment then it would probably not work well to use that internal diode. By continuing to use this site, you are consenting to our use of cookies. Was thinking single direction, even though you obviously said h-bridge. Yes, place them on the drain and source of each mosfet. Read these app notes from International Rectifier and Fairchild about mosfets It so funny how people never read for themselves It has source to drain diode built irff511 for inductive loads.

It gets even worse if you are in an h-bridge configuration. Electro Orf511 is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Read the app notes. The problem is that obviously geometry is involved and i dont have very advanced notions i am 14 after all and I’m sure they thought it could be used for that at some point, until they started finding failures using it that way.

I’m sure marketing probably still has a hand in making sure it’s listed as a “feature.
