Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, datassheet and gadgets. Sorry, was braindead on the diode. I have doubts that it is a more practical way of doing with npn and pnp combo I also satasheet to know where to place the flyback diode please. As a quick example of an application that does not require an extra diode, consider a relay driver where the relay turns on and off once per hour.

Yes, place them on the drain and source of each mosfet. I’m sure marketing probably still dataaheet a hand in making sure it’s listed as a “feature. Welcome to our site! Forums New posts Search forums. That is probably just something added by the creator of that web page. This is probably the biggest factor in determining if you datashwet use the internal diode or not.

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.


However, i have a geometry question that is burning my lips but i only see my father in two days I’m sure they thought it could be used for that at some point, until they igf511 finding failures using it that way.

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. Right on the motor if you can.

It gets even worse if you are in an h-bridge configuration. You can easily use all Irg511 fets, though you will need a bootstrap cap and diode on the high side drivers. For a better experience, please enable JavaScript in your browser before proceeding.

Some good simulations might tell what is best to do with a given application, and some prototype measurements would also help. This means that irv511 transistor using the internal diode has to dissipate an extra amount of power, not only 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.

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 rif511 and repeat, like a sort of sonar. If so, because the current will go in both direction in the motor, placing a diode will shortcut the whole thing.


Place 18v zeners between the gate and source to eliminate transient high voltages and self-latching.

The problem is that obviously geometry is involved and i dont have very advanced notions i am 14 after all and Read these app notes from International Rectifier datashet Fairchild about mosfets That just seems silly to me. Media New media New comments Search media.

Read the app notes. 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.

Thread datqsheet breadboardguy Start date Jul 22, You must log in or register to reply here. 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.

Will i be fine to use only the irf on my robot? This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.
