D²PAK as I²PAK

[MINING123STUDIOS]

I want to mount a D²PAK (surface mounted ) diode as an I²PAK diode.
Is it possible or not?

I don’t know how big the difference between those two footprints is, but maybe you can use the link below to get an estimation of whether it can work.

[tutorial] Test fitting Footprints

A small demo to show how I test fit footprints. It’s a combination of a few things to make it work perfectly. The first step is to print a PCB mirrored on a piece of Paper: PcbNew → File → Print → Options Mirror → Print. 2nd step: Take a needle and pre-punch all the mounting holes into the paper. (For the large holes I used a hole punch). 3rd step: Carefully put the connector into the sheet of paper. 4th step: Take a picture or scan the whole contraption with a flatbed scanner. This make…

Also, it’s easy to modify footprints in KiCad. It may be possible to have either of them fit reasonably well with some small modifications.

Edit I just did a short search for I²PAK and I found this:

In this datasheet:
www.st.com/resource/en/datasheet/stb20n65m5.pdf

So it looks like both are based on a TO220 with a cut of tab. I guess you can make it fit by bending the pins a bit and cutting them to length.

d2pak is just the smd variant with bent leads

I think it depends if in your diode pin 2 is used or not.
In SMD pack it can be used as it has the best heat dissipation.

Two bent, one cut.

it doesn´t use pin 2 and i will mount the tab to a heatsink.
