@Ted S posted:When would you use one, relative to the other? Thanks in advance for sharing your wisdom and experience!
Example, let's say a large heavy duty electric forklift battery charger. It's going to be used for hours, often overnight or all day charging a huge set of batteries. In that case, I'm going to use stud mounted heavy duty diodes rated for that kind of heavy duty long lifespan thermal load.
Now say I'm building a train control circuit board like a PS1 lower power and control board. Nowhere near the load and thermal heat buildup, but also, I do not need the huge power handling and size of a stud mounted set of diodes.
In our common usage, you may see those diodes used inside an old postwar ZW transformer. Either type could work, some opt in for the larger stud mounted version because there is more space and the ZW can output a fair amount of current in the short term, so a big beefy diode is not a bad thing. But others are perfectly happy using the smaller barrel type and given only being used for whistle function intermittently, it's well within the thermal scope.
