Hi Hans,
“The 3.3V Zener on the 3.3V SMPS board”, did you mean “3.6V Zener”? I have placed an order of 3.6V 500mW from digikey yesterday.

The 5.6V Zener on the 5V SMPS board is now 5W (first PCB revision, it was 500mW. 5W is better).?
The 3.3V Zener on the 3.3V SMPS board is 500mW and MUST REMAIN 500mW, do NOT change it to a higher rated part, it won't work!

Would it make sense to order a slightly higher rated replacement part or would it be wiser to stick to the 500mW surface mount component?
Ronan, I remember a Post from Hans G0UPL a while ago. He told NOT to change the type. It was something about the voltage characteristic.
