Re: transistor help needed

24V stepper motors driven by 25V rated MOSFET¡¯s is a really bad idea. That¡¯s too close to the their limit. A single coil spike could destroy them. From this perspective, The BUZ seems a better option. I¡¯m assuming those stepper motors will not consume anywhere near 11A. As long as they have a good heat sink assembly, it¡¯s worth a try. If you¡¯re going to buy them on purpose, I advise looking for something better. If you already have them, and assuming a hand size stepper motor, 11A seems more than enough. ? So, yes, they might work. (I assume no responsibility for any smoke clouds! :D ) ? Nuno T. ?

Subject: Re: [electronics101] transistor help needed ? well at the moment aan arduino uno is driving the aod472 fets to drive a nima 23 stepper,i have made a pcb in eagle the buz 72 would be better to mount on the pcb than the d2pak fets,i just wondered if they would work,i am using 24v for the stepper. -- Nuno T.
