    Hi.

    What is the best replacement for the SES5001 rectifier.

    I'm building a bi-polar step motor driver, based on the L293DNE IC. In the datasheet for that IC, there is a schematic showing SES5001.

    Can I use any 50v 2A rectifier?

    No. It's a 100 nanosecond, 50 volt, 2 amp diode. .975Vf@1A

    Can you finish from here?

    I saw that datasheet. That's how I saw it was a rectifier.:)

    How about the 1N4001?

    50V 1A 1.1Vf@1.0A

    0.13Vf different.
    I couldn't find anything about nanoseconds in the 1N4001s datasheet.

    ... and it is 1A "smaller". Can you say that?

    It's a fast switcher. 1N4000 series don't stand a chance. You have to do a parameter search on the site where you buy parts. Mouser is down right now, so My favorite isn't working. I could guess what supplier you use but I'd rather ask.

    OK, I've tried to search for the SES5001, but no hits. :( (Jameco, Digikey, tried Mouser but as you said, and Elfa...)

    I'll start the parameter search.

    Thanks.:)
