Bridged Rectifier mounted on Heatsink - to isolate or not?

[calvinhpk]

I plan to use Vishay GBPC3502-E4/51, Bridge Rectifier, 35A 200V, 4-Pin GBPC for F5 power supply and plan to mount them on the main heatsink sharing with F5 amp, or probably on the base plate of the chassis
Shall I isolate them with mica sheet + thermal compound? or just mount directly with thermal compound?

just thermal compound, the case is isolated.

thanks for the reply.

will there be issue if the bridged rectifier is mounted near the power amp or pre-amplifier PCB?

Ideally, you want to keep any signal lines away from a bridge rectifier, as you could inject noise. Keep as much distance as possible from rectifier and any PCB's. If you have a picture of your setup, I'm sure people will chime in.
