Datasehet 18v zeners between the gate and source to eliminate transient high voltages and self-latching. I blame lack of coffee. But, why take the chance in blowing up your mosfets because you don’t want to use an extra diode that costs a few cents?

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. For a better experience, please enable JavaScript in your browser before proceeding.

They both say using the body diode for inductive current can blow the fet. I’m sure marketing probably still has a hand in making sure it’s listed as a “feature.

Yes, but it says nothing about using it for inductive loads. Click here to register now. 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. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb However, i have a geometry question that is burning my lips but i only see my father in two days 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.

Thank you evryone to had answered my questions so fast, electro-tech-online really is a great community. Hi, I can add a little information here 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.

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.

Was thinking single direction, even though you obviously said h-bridge. Right on the motor if you can. I’m sure they thought it could be used for that at some point, until they started finding failures using it that way. Adding an extra diode would really be silly here.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. If you read the actual datasheets on the product, nowhere does it say the body diode should be used for inductive loads. Read these app notes from International Rectifier and Fairchild about mosfets You can easily use all NMOS fets, though you will need a bootstrap cap and diode on the high side drivers.

It gets even worse if you are in an h-bridge configuration. Just saying hello Started by MichaelaJoy Yesterday at 6: This helps reduce the ringing effect from the transistor turning on and off. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Thank you if you post of course.

That is probably just something added by the creator of that web page.

BEAM Circuits — Steve Bolt’s H-bridges In my drawings i only used n-channel irf to source the motor and to complete the circuit to the – terminal of the battery but on that website, two type are use npn and pnp. You must catasheet in or register to reply here.

Will i be fine to use only the irf on my robot? A careful analysis has to be made and some prototype measurements would verify the need for any extra diodes. This means that the transistor using the internal diode has to dissipate an extra amount of power, not datasehet while the thing is in conduction, but also when the diode is in conduction, which increases the total power dissipation of that one little package even if the forward voltage of the internal diode wasnt higher than normal.
