Do MUR860 rectifiers need heatsinking? I can save a lot of PCB space if I get rid of these heatsinks. For an amp PSU, +/-40V, possibly up to +/-80V, for use with LME49830 + mosfets
If it is well within the specification of less than 8Amps, probably doesn't need a heatsink. Try it and check it.
Hi, I'm new when it comes to using these TO-220 diodes. I'm about to place my order for parts.
Why do you say MSR860? Care to expand on that?
I checked datasheet and MSR860 has 1.7V drop, 8A rating, 120ns recovery time, +150C Max Temp. Also cost $1.21 each.
MUR860 has 1.5 Voltage drop, 16A rating, 60ns recovery time, and +175C Max Temp. Cost $0.96 each.
They sound better, if you can use it for your load.
Also none of the crappy manufacturers produce them. You have to watch which manufacturing company made the MUR860. You can search Peter Daniels and MSR860, MUR860 for information on opinions of a refined man.

I can buy either MSR or MUR, both made by ON Semiconductor.
I think I'll stick with the MUR860, specs seems better overall than MSR, just looking at datasheet.

"They sound better" just does not satisfy me. Can you elaborate?
How? Why? what's different with the MSR860 that makes it sound better than the MUR860?
You see, all the preamps I've done in the past were just rectified by low power W02J bridge rectifiers. This new one will be a power supply for a power amps.

The sound is considerably more pleasant. I can guess why, but it doesn't matter. The big notable thing is soft recovery. As of so far I'm sold, and soft recovery works with my PSU. Soft recovery tends to generate less RF.
LME49830 stereo with 2pr 1058/162 per channel, 30,000uF per rail runs fine off a MU860 single bridge - 4 diodes - without heatsinks on the diodes. Lots of power and goes nice and loud 🙂
