   Is the 1N470 an obsolete part? I sure would appreciate it if someone could
   tell me the voltage of this diode.

I can't find the 1N470 in any of my current data books or catalogs, so I
assume it is indeed obsolete.

My hoary Motorola "The Semiconductor Data Book" indicates that it's 6.8
volt nominal Vz, 200 mw.  Min and max Vz are 6.2 and 8.0 respectively; the
1N470A is a 5% tolerance version whilst the 1N470B is 1%.  Motorola lists
the 1N5235B as a "similar" replacement.  Note that the shiny new Motorola
books just give the suggested replacement without giving the specs on the
original part --- there are virtues to being a pack rat.
