BZT52 is a SMD-zener

[Perdita-Olio]

Maybe a little late but I saw the PCB and the schematic diagram and I noticed in the schematic diagram the zeners are BZT52.
But they are SMD.
Which axial zener with the same properties I can use? A 1N4733A or a BZV85‑C5V1?
On Hackster.io these both zeners were mentioned as 3.6 volts, 0.5Watt.
Are these zeners working quite well?

Hello @Perdita-Olio, sorry for the delay to reply to this question. In the project official documentation it is mentioning the same as you see in Hackster.io, 3.6V@0.5W. I would stick with that. You can try 1N4729A or BZV85-C3V6. I hope this info helps you with your project.

Kind Regards,

Thanks for your reply. I wil try it with the mentioned zener-diodes.
One more question: what's the difference between the PCB's V2RV1 and V2RV2?

Sorry, I've found it. Different silk on the PB4 and 5.

Best regards.
