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.
