I'm going to guess that likewise it's a TVS diode.  in fact... I'd guess it's a SMAJ5.0A-TR

(see pages 7 & 8 for marking on these diodes)

Did this likely result from a power polarity issue?

My best guess is some sort of zener voltage reference diode, but I'm somewhat at a loss for ideas.  I uploaded a couple photos to flickr, linked below.
