Does anyone have a library for Standard 1N400X ( 1n4001/2/3/4 etc ) Through Hole Diodes, Please. I am new to Libre PCB and havent yet figured out how to make my own Libraries yet.

I’ll add them to the base library, should be ready tomorrow.

If you didn’t see it yet, here’s a tutorial: [Create a Local Library | LibrePCB Documentation](https://librepcb.org/docs/quickstart/create-local-library/)

But as said, I will take care of the diodes.

EDIT: Here the new pull request:

>
> \##### SUMMARY
> Like the already added generic transistors, these diodes are very… generic as well (manufactured by many companies) and very commonly used, so it will be useful to have them in the base library:

> The packages DO-41 and DO-35 already existed. Also added many MPNs for these devices.

@Daniel the diodes are now available. Just update the LibrePCB Base library in the library manager.
