I’m sure marketing probably still has a hand in making sure it’s listed as a “feature. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb Right on the motor if you can.

To participate you need to register. If so, because the current will go in both direction in the motor, placing a diode will shortcut the whole thing. You must log in or register to reply here. 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.

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.

Was thinking single daatasheet, even though you obviously said h-bridge. Thank you evryone to had answered my questions so fast, electro-tech-online really is a great community.

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 datasheft dissipate. 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. Yes, place them on the drain and source of each mosfet. The extra power dissipation has to be carefully examined relative to the application.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Place 18v zeners between the gate and source to eliminate transient high voltages and self-latching.

Also place a pF ceramic cap between the drain and source of all the mosfets. Welcome to our site! Started by fastline Yesterday at eatasheet A careful analysis has to be made and some prototype measurements would verify the need for any extra diodes.

Secondary usually is the reverse recovery, which can be longer than an external carefully located high speed diode. I blame lack of coffee. However, i have a geometry question that is burning my lips but i only see my father in two days 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.

That is probably just something added by the creator of that web page. Sure, many people get away with it, but why take the chance when a simple schottkey is much better at the job anyway. Thread starter breadboardguy Start date Jul datashedt, It gets even worse if you are in an h-bridge configuration.

But, why take the chance in blowing up your mosfets because you don’t want to use an extra diode that costs a itf511 cents?

This is rif511 the biggest factor in determining if you can use the internal diode or not. This helps reduce the ringing effect from the transistor turning on and off.
