I can't find the right category under Surface Mount device to draw a SOT-89 package.

There are the SOT23 category or the similar SOT223 category, but is't the same.

Someone have ideas? 

Thanks

There is no Calculator for the SOT-89 due to the various shapes of Pin 2.

You can download specific mfr. SOT-89 packages from Parts on Demand (POD).

There aren't very many of these component packages, so we build all SOT-89 footprints in PADS Layout per the mfr. recommended Land Pattern and put the PADS p/d files on POD for customers to download.

Example: search for DIODES INC. + P/N: ZXTR2005Z-13 and you will find a SOT-89 from that mfr.

I also attached a generic SOT-89 in PADS p/d format. You can use the PADS to CAD translator to convert it to your CAD tool. But there is a disclaimer that most mfr. make their SOT-89 slightly different.
