Thank you for the link. I'm looking for documentation on that kit to see what components they are using.

This is a, "Teach a man to fish" kind-of-thing. Unfortunately, I have to learn everything the hard way.

Thanks again for the help!

First of all, thank you so much for all the information provided in this post. I'm just getting started in electronics so I'm as green as they come. I appreciate your patience.

I am also currently developing a L297/L298 based motor controller. According to the schematic provided in the L279 Datasheet;

http://www.st.com/stonline/books/pdf/docs/1334.pdf

...the 8 x 2A Fast Diodes can be packaged as a L6210. I've found this part;

It's reletively cheap and I want to use it for my application.

However, the diagram is for a "Two Phase Bipolar Stepper Motor Control Circuit." My question is, can I use this same circuit in a Four Phase Unipolar application? More specifically, are the motors connected to the L298N in the same configuration, allowing me to use the L6210 for the diode bridge?

If not, can someone please suggest a proper diode to be used in this application? I'm looking at this part;

...but I simply don't know if this will work.
