Newbie question Unknown component

Can anyone tell me what this SR 6863D and what an equivalent might be? I Googled the number looking for data sheet for quite a while but nothing came up.

The circuit is the driver circuit for one of those circular fluorescent magnifier lights and it just went "phut".

There are two burnt resistors and these two ICs. Since these ICs are the only active parts on the PCB, I thought I'd try replacing them along with the resistors. Just a guess on my part, I'm afraid.

Thanks in advance

Google is your friend, try it.

I did and found this:

OK, I know it is in German, but look halfway down the page, there is a bit of a datasheet in Japanese and English. That should get you going in the right direction.

The 10Uf 400V capacitor in those units dry out & fail due to heat. So I would replace that as well.

Thank you. Noted.
