Yeah, I'm not really comfortable with that. How do you ensure current is evenly shared between them? (Given that if one shorts, your diodes go poof!)
Now that's an idea... It can handle 5 amps (with proper heatsinking), so that might work.And with the LM338, directly compatible in this case, you might not even need to do that.
True. I actually built a large stack of 4008 diodes for exactly this purpose after my latest Flexmod failure...As to risk, try it on something less important
Hmmm. Ok, you've got me thinking about it at least!
