Diablo II: The Awakening
From Diablo Wiki
This roleplaying game was released as part of the Advanced Dungeons & Dragons 2 ruleset before Diablo II itself was released. Since the game was released later, it includes content not available in the PC game.
This one is different than the other DnD products for Diablo II, however, since it's for the ADnD 2 system rather than DnD 3.
This is what RPG.net has to say about it: 
- This action-packed epic takes the world of the Diablo II computer game and translates it into the ultimate AD&D adventure. You can create AD&D heroes with a Diablo twist or use heroes from any AD&D campaign, then send them off to challenge terrors once found only on a computer screen. The adventure starts in Tristram, the battleground of the original Diablo game, where Diablo, Lord of Terror, rules a legion of demons. There, the heroes explore the mysterious Monastery - full of dangers and challenges pulled right from Diablo but enhanced for your tabletop game!
