Default SMD diode ID please

Can anyone help identify the diode below?

The plastic body of the diode below is ~0.175" x 0.103". The forward breakdown voltage is ~0.44v. The reverse breakdown was higher than the 210v limit of my power supply. They seem to be very leaky when checking on ohms instead of diode check.

Others on similar boards were marked:

X3 72
X3 6N
X3 62

Newer versions of the same board have diodes marked:

XH3 8401

Thanks in advance.

I can't help, but I'd like to thank you for the very clear pic.

IMO, this is a nice example of how to ask for help

I'm sorry. The Zener diodes that I was thinking of are SOT23 - it's not the one that you are looking for .

It's definitely an SMA / DO-214AC package. Doesn't look like On Semi or Diodes Inc. labeling to me.

Thanks for the responses.

With the package information, maybe I'll have a better chance of finding it.
