I have to calculate a D2PAK footprint from ST Electronics.
In the library expert I only see the option to calculate a TO (DPAK). Is it the best way to use the maximum with for the e1 value since the D2PAK has a kind of a T-shape?

I bet the component mfr. recommended pattern is not T-Shape, rather it's a full pad used for thermal relief. You can use the TO (DPAK) component family to create a D2PAK footprint. You can also select the "Footprint" tab and enter the mfr. recommended pattern (after you enter the component dimensions to calculate the IPC pattern). |
