I could be wrong, but suspect the three legged diodes are actually a
reference to three-terminal current regulators - or possibly to voltage
regulators. These were mentioned a while ago as a method of getting
simple current regulation for CS generator

Subject: Re: CSDiodes with 3 leads ( Question and Use )
I would not recommend using a constant current diode for that. I would
use the method I am using on my CS to make the current 80 mA. Take a
7805 5 volt regulator and connect a resistor between the output and the
control leads
Thanks Dan, Marshall,
I want to build a couple of LED navigation lights for my sailboat, each
of which may require more than one series string of LED's to cover the
arc uniformly, thus my need for 20, 40, or 80 ma, depending...
Depending on the voltage drop of the LED's used, 3 or 4 per string

The legs are already shorted internally, so, it doesn't matter which one
is used. Shorting them externally just makes sure one hits.
Verify with ohmmeter.
That two legs are there, as one, serves the assembly robots as a way to
orient it without having to be able to read.

Interesting, they call the gate, the cathode, never seen that before. Anyway
from the picture of diode.jpg you would connect the
middle lead to the bottom one to make it a constant current diode, and the
anode need to be the positive lead.

Thanks for the links. I looked
It is a current limiting diode, not just a regular diode. It is used to
limit the current to 1 ma
The third leg can be used to adjust the current I believe. the point of
this diode is to limit current while make CS.
It is used with DC current in my setup so its not a diode for the
purpose of
