It gets even worse if you are in an h-bridge configuration.

I blame lack of coffee. To participate you need to register. 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.

If the application can stand the extra loss in power and the device itself datasjeet overheat, then there is no reason not to use the internal diode. By freewheel diode, do you mean fly back diode? It dose say It has source to drain diode built in for inductive loads.

They are incredibly enlightening. Right on the motor if you can. The extra power dissipation has to be carefully examined relative to the application. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at On the other hand, if the device overheats or has to be used in high heat environment then it would probably not work well to use that internal diode. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb Potentiometer Questions Started by norbss Yesterday at This helps reduce the ringing effect from the transistor turning on and off.

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.

To get my h-bridge to move, i need sensor, mine is a ir sharp range finder on a servo motor i might also make a version with an lcd screen and sonar range finder to see in total dark the range finder moves of 1 degree, takes the range of the object in front of it and repeat, like a sort of sonar. Also place a pF ceramic cap between the drain and source of all the mosfets.

That just seems silly to me. Datadheet these app notes from International If511 and Fairchild about mosfets I’m sure many people think that’s why they are there, just from looking at the datasheets. I need to build a h-bridge for my mobile breadboard aka hammerhead cause of its shape.

I’m sure they thought it could be used for that at some point, until they started finding failures using it that way. Will i be fine to use only the irf on my robot?

h-bridge fet transistors ?

I’ve seen circuit where they place it between the drain and source of each transistor, will it do the job? 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 drive signal that actually goes a little negative rather than to zero as many designs do N-MOSFET application.

Yes, but it says nothing about using it for inductive loads. Secondary usually is datashdet reverse recovery, which can be longer than an external carefully located high speed diode. Sure, many people get away with it, but why take the chance when a simple schottkey is much better at the job anyway.

Thank you evryone to had answered my questions so fast, electro-tech-online really is a datasheet community. Was thinking single direction, even though you obviously said h-bridge. Yes, place them on the drain and source of each mosfet. For a better experience, please enable JavaScript in your browser before proceeding. That is probably just something added by the creator of that web page. Ddatasheet, why take the chance in blowing up your mosfets because you don’t want to use an extra diode that costs a few cents?

Click here to irt511 now. They both say using the body diode for inductive datadheet can blow the fet. You must log in or register to reply here. Sorry, was braindead on the diode. It so funny how people never read for themselves It has source to drain diode built in for inductive loads. If you look on any data sheet irc511 will find that that dqtasheet diode has a rather high forward voltage, much higher than an external Schottky would have for example.


On the other hand, a very high speed H bridge may benefit from adding extra diodes because doing irr511, if not anything else, moves some of the heat out of the transistor package and therefore keeps it cooler.

I actually designed converters for a company way back when and have viewed a multitude of other designs that were similar that were designed by other people that had a lot of knowledge in the field.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. You can easily use all NMOS fets, though you will need a bootstrap cap and diode on the high side drivers. Thank you if you post of course. Forums New posts Search forums.

A careful analysis has to be made and some prototype measurements would verify the need for any extra diodes. This is probably the biggest factor in determining if you can use the internal diode or not.
