Diode spacing??

[Ambugaton]

Are there any general rules for diode spacing for a SS rectifier? My space is a little tight and the leads for some of the diodes will be about 9/32" apart. Is that safe?

> about 9/32" apart

1/4"? Seems generous to me.

[sluckey]

9/32" is fine for 1N4007 or other DO-41 case style diodes.

Thanks. I'm completely ignorant to all of this and didn't know if there was a risk of arcing if they were too close.

[kagliostro]

The arching risk depends on the voltage

if you use 1000v or higher B+ then you must pay particoular attention as to avoid risks

a bit less if B+ is in orther of 800v and so on

May be here you can read something of interesting also if dedicated to PCB traces and SS components
