Subject: Vishay PowerPAK 1212-8 Case Code
Date Posted: 25 Jun 2015 at 12:19pm
I'm looking to build a PCB decal for PADS Layout base on the one on following doc.:
http://www.vishay.com/docs/73133/si7802dn.pdf" rel="nofollow - http://www.vishay.com/docs/73133/si7802dn.pdf
 
Is there a footprint already done in Library Expert on this one that I can slect from the FPX file?
 
If not, what will be best:
a) Single pad for Drain or
b) Do a 8 pad parts with thermal pad offset so it short pads 5-8?

The Vishay PowerPAK 1212-8 Case Code is on Parts on Demand (POD) for 2 credits.

I guess I can use a couple credits, from ones I got when purchasing PCB Libraries, and take the decal you have.
However I would like to understand why your X and Y dimension are 3.4mm?
It's not max dimension, neither what I could call typical which is between 3.0mm and 3.61mm and give something like 3.35mm.
Is it because dimension is rounded up from 3.35mm to 3.4mm?

POD parts use the nominal dimensions because most people want Nominal 3D models and Library Expert exports 3D models.

However, it does not make any difference because everyone uses something different.
 
The user can easily change the values to whatever you want once you own the part.

OK, then I assume you rounded up to 3.4mm and use it as nominal dimension.
I'm taking your part, you will then deduce 2 credits from what I have, how do we procced from here?

Hi Tom,
I tried to download as you mention, however POD doesn't start the dowload.
In account I see my user name so I guess I'm logged.
I've selected Vishay in Manufacturer and paste PowerPAK 1212-8 in Case Code windows.
Click on SERCH POD which start a search, and after nothing happen.
I've tried few combination but nothing.

I cannot replicate this issue, using IE11 on a test user account. Let's discuss this offline, we'll figure out where it's going wrong.
