Title: Cree CSD01060 Schottky rectifiers
Post by: Sleepybird on March 28, 2018, 10:15:55 PM

On the power board are two Cree CSD01060 Schottky rectifiers of TO-220 style.
How much heat is dissipated and will install of heatsinks lengthen their longetivity?
Thanks in advance.

I re-biased my tubes this morning and touched the rectifiers and they are not very hot or warm at all....

I have a thermocouple but its down in the garage and I am too lazy to get it right now...caught up in just listening!!!

I will measure later and post what I measure.

Less than 1/10 of a watt should be dissipated in each diode.

If you put heatsinks on the didoes, you will not do anything to prolong their life, but if these heatsinks touch each other or touch any other metal parts in the amp, you will at minimum blow a fuse.
