Very interesting. The 1N4007 seem to be very versatile devices.
They are available with a SOD-57 glass envelope, too (1N4007G?).
These are fairly well photoconductive. When illuminated ...

While many companies* are making 1n4007G glass-passivated diodes,
it appears they all cover the glass with plastic. I wonder...
where one can get a 1n4007 with an all-glass package these days?

Bytesonic, Leshan Radio, Formosa Microsemi, Gulf Semiconductor,
Dachang Electronic, Goodwork Semiconductor, etc.

How many do you need, and can you use ones pulled from PC boards? I
may have some left that I pulled from damaged boards.
