This IC, 5TB06-700BW, is sitting on a motor controller PCB (manufactured in 1998). Pin 1 and 2 are attached to 230V lines, while pin 3 is attached to the output-pin on a U2010B phase control IC. The motor does not run so I suspect that the TO-220 IC is dead, but I cannot find any information on google regarding what kind of IC it is so I cannot confirm it.

What IC is it?

I think the first '5' is a 'B".

A BTB06 is a '6A standard and Snubberless™ Triac'
