VFE Dragon diode

[wefunk222]

Building a VFE dragon. Question with one of the three diodes. I have the 1N4148 and 1N5817 correctly figured out.
List of parts on PCB layout diagram and BOM lists a 20v Zenner(directly east of the 12F509)
The PCB itself and he PCB layout diagram has 18v for the Zenner diode.
Which one is correct?

Thanks!

With the VFE projects, defer to the BOM. The pcb values changed over time with project development. The BOM usually lists the most up to date and correct values. Also, I just checked the VFE DIY site and the part listed there is a 20v zener. I'd go with that.
