@AnindoGhosh don't know that name but it is a reformed version of the PTH with the leads bent and trimmed in second operation on the molding machine. Don't know if that helps ...
@rawbrawb I needed a package name to check for any popular footprints for it: The E and C are high current, I need to figure out if there's something that needs doing around the pads for those two.
@AnindoGhosh High current just means keep your tracks wide. If it's not super-high impedance or high voltage I don't think you need to worry specially about separation distances.
But how high is high current? I can't imagine an optocoupler doing even 1 A.
@ThePhoton Nahh, the 817 is a baby opto. There's a triac driver in the same package which does more, but I can't find the datasheet / part number right now.
@ThePhoton But the triac driver will merely drive the triac. The current board uses a low voltage sugarcube relay for the prototype, once this stabilizes the triac driver and triac will be swapped in on the next layout.
@rawbrawb Dunno. It's bizzarre. All (?) the violations are for silkscreen over pads and solder mask sliver. Which never got caught by the online DRC until just now.
