Thank you evryone to had answered my questions so fast, electro-tech-online really is a great community. Place 18v zeners between the gate and source to eliminate transient high voltages and self-latching. Click here to register now. It gets even worse if you are in an h-bridge configuration. Sure, many people get away with it, but why take the chance when a simple schottkey is much better at the job anyway.

Adding an extra diode would really be silly here. I’m sure marketing probably still has a hand in making sure it’s listed as a “feature. 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.

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. Read the app notes. A careful analysis has to be made and some prototype measurements would verify the need for any extra diodes. If you look on any data sheet you will find that that particular diode has a rather high forward voltage, much higher than an external Schottky would have for example.

By freewheel diode, do you mean fly back diode? For a better experience, please enable JavaScript in your vatasheet before proceeding. I have doubts irg511 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. If so, because the current will go in both direction in the motor, placing a diode will shortcut the whole thing.

h-bridge fet transistors ?

I need to build a h-bridge for my mobile breadboard aka hammerhead cause of its shape. Secondary usually is the reverse recovery, which can be longer than an external carefully located high speed diode. You must log in or register to reply here.

Yes, place datashet on the drain and source of each mosfet. Articles Top Articles Search resources. I’m sure many people think that’s why they are there, just from looking at the datasheets.

Hi, I can add a little information here If you read the actual datasheets on the product, nowhere does it say the body diode should be used for inductive loads. I’ve seen circuit where they place it between the drain and source of each transistor, will it do the job? However, i have a geometry question that is burning my lips but i only see my father in two days Also place a pF ceramic cap between the drain and source of all the mosfets.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at 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.

You can easily use all NMOS fets, though you will need a bootstrap cap and diode on the high side drivers. This is probably the biggest factor in determining if you can use the internal diode or not. 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. Will i be fine to use only the irf on my robot?

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. Just saying hello Started by MichaelaJoy Yesterday at 6: That just seems silly to me.
