Default D-PAK and D2-PAK fred diodes - clarification in mounting

Iím trying to use surface mount D2-PAK Hexfred (IR HFA06TB120S) to construct a compact full-wave bridge. However, I find the data sheet ambiguous as to the proper mounting configuration.

As with the D-PAK, it appears to be more straightforward when the 2 left/right pins are clearly shown as anodes and the tab and middle pin as cathodes. With the D2-PAK, the left pin is described as N/C (I canít find an exact description for this label in the data sheet), the right pin is A (anode) while the tab is K (base, but seems like a cathode terminal). Anyone kind enought to offer clarification here?


Also, what will be the appropriate heatsinking method for this type of SMD package?

thanks, in that case I think it safe to assume that they can be used directly as drop in replacements for conventional diodes (IN4007 types) in a bridge configuration.

this rather sounds a straightforward and more simplistic approach but I haven't yet seen posts showing or illustrating this kind of work by other forum members neither in pics or diagrams.

but there seems to be a deluge of snubberized TO220's everywhere. just an observation.

i think it to be a practical solution over the latter where space contraints and economics are critical considerations given equal or better performance.
