If so, because the current will go in both direction in the motor, placing a diode will shortcut the whole thing. 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.

That just seems silly to me. Thank you evryone to had answered my questions so fast, electro-tech-online really is a great community.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Was thinking single direction, even though you obviously said h-bridge. Will i be fine to use only the irf on my robot? Forums New posts Search forums.

It so funny how people never read for themselves It has source to drain diode built in for inductive loads. Hi, I can add a little information here Place the freewheel diode as close to the motor as possible. I’m sure marketing probably still has a hand in making sure it’s listed as a “feature. Read the app notes. I actually designed converters for a company way back when and have viewed a multitude of other designs that were similar that were designed irff511 other people that had a lot of knowledge in the field.

To participate you need to register. The extra power dissipation has to be carefully examined relative to the application. If the application can stand the extra loss in power and the device itself wont overheat, then there is no datashdet not to use the internal diode.

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 need to build a h-bridge for my mobile breadboard aka hammerhead datasgeet of its shape.

Sorry, was braindead on the diode. Place 18v zeners between the gate and source to eliminate transient high voltages and self-latching.

Started by fastline Yesterday at 8: Some good simulations might tell what is best to do with a given application, and some prototype measurements would also help. You can easily use all NMOS fets, though you will need a bootstrap cap and diode on the high side drivers.


The integral body diode sees a current spike once per hour that lasts probably 1ms or maybe even 10ms, but after that it has almost 60 minutes to cool back down. A careful analysis has to be made and some prototype measurements would verify the need for any extra diodes. Adding an extra diode would really be silly here.

They are incredibly enlightening. You must log in or register to reply here. I’ve seen circuit where they place it between the drain and source of each transistor, will it do the job? Click here to register now. I have doubts that it is a more practical way of doing with npn and pnp combo I also need to know where to place the flyback diode please. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb The problem is that obviously geometry is involved and i dont have very advanced notions i am 14 dataheet all and
