Something like the SiA471DJ comes in the same pinout and package, has almost 1/10th the on-resistance, and over 10x the current rating. Moreover, its datasheet does not have such a lengthy disclaimer about its abilities:
If I were in the same situation I'd choose that part for a replacement --- sources online show it's basically the same price, and why replace it with the same failure-prone part just to risk it doing the same thing again? This isn't even a high-frequency application, it's just a power switch.
All mosfets are like that.
The marketing folksbL at Toshiba just were not able get it removed, or they have had one too many complaint from folks running them near the absolute max while not cooling them properly.
