It's called junction melt down.

Howdy all,

I've got a client who heard a rumor of a safety requirement for
semiconductors that entailed having some thermal cutoff.  This is a
semiconductor requirement, not an end-product requirement.

Has anyone heard of this in an existing or upcoming requirement?

Thanks,
Sam
