[HomeBrew] Help identifying a component; further testing

[pete wokoun, sr.]

Hi
  Thanks to all who offered their suggestions.  Most of the suggestions were 
they were a triac/scr origin.
  They don't test as any scr/triac.  I would get a gate-cathode junction 
that I would forward bias if it was.
  I was able to put up to 140 volts across any of the 3 terminals (current 
limited, of course) and get NO current flow in any direction.  I started out 
at zero and slowly came up.  I was able to detect as little as 0.1 uA.
  Capacitance measured 6-7 pF between the stud and either terminal.  Also 
the same capacitance between both isolated terminals.  This is too low for 
any type of bypass cap.
  Resistance is >20 megohms between any two terminals.

So, no winners, yet.

Anyone want one to check out?  I only have 5.
