3996 Zener diodes

I think the R reverses the cathode and anode as stud as compared the the regular 3996 or the 3996A. 

 

1N3996 and 1N3996A has this:

True dat....but if we're putting them back to back as in a Klipsch AA crossover is it going to matter?

Not sure. I thought diodes had a flow path.  

A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance

Zeners are special critters. In one direction(polarity) they stop conduction until their "zener" voltage is exceeded. Then they "avalanche" and conduct which limits the voltage across them to their zener voltage. In the other direction they conduct like a regular forward biased diode.

I just noticed what you said earlier about them being connected "back to back". I didn't catch that... Those are interesting little diodes.
