Comets hit the sun all the time. Far larger than the average meteor.
You might find this video, which looks as if the sun responds with a coronal mass ejection as a result of being hit by the comet.
But the comet is far too tiny to do this. It is just a coincidence. If you look closely you can also see that the coronal mass ejection happens before the comet could have hit the sun (sun shown as the white circle - the darker circle is an area that is blocked to protect the telescope).
Soho spots numerous comets and most of them dissapear before they hit the sun.
More about them here:
These comets are of order of a few tens of meters. Studies of SOHO Comets
I don't know the answer to the question except to say pretty big.
I wouldn't be surprised if even an object the size of Mercury just melted into the sun with no effect. Except - if it had ice - a spectacular tail developing as it approached the sun before it hit it. But don't have any figures for that.
