Tristan probably goes back to the old Pictish name Drustan. In medieval French tales it was likely reshaped by association with the French word triste, meaning "sad", which coloured the romantic legend around it.
The name became famous through the medieval story of Tristan and Iseult and has stayed in use ever since. Its literary depth and long history give it much firmer roots than many modern sound-based names.
