@ sregor thanks for the clarification, I understand now
@ BinaryMike thanks for quantifying
@ Oilmaster
1) my final order has already been placed (my "current" final order
) and it includes the Fairchild part you linked
2) searched Mouser and Digikey for the Microsemi low noise zener and they are not there
3) will get back to you to discuss the topics of bypassing zeners and also whether or not there is additional noise filtering in the phono preamp and tone boards of my project amp, there are some caps in there whose function I do not understand.
But first...
What are some thoughts as to the best way to mount zeners, or rectifiers, or any diode, to maximize heat dissipation:
.... Heat has to flow readily into attached hardware for the diode to actually meet its dissipation spec.
.... keep them off the PCB (1/2'') to enable some natural air draft around them for heat dissipation.....
Guys, which is the way to maximize heat dissipation? Short leads, which implies mounting close to the board and less air space? Or mounting higher off the board to give air space but which would require longer leads?
BinaryMike, when you say "attached hardware" do you mean the PCB tracks? Other than a solid solder joint, is there a way to maximize the mechanical connection?
