0.4W zener but what voltage?

I can't help, but FWIW, the Internet has references to "QSCH" devices
made by HP.

HP also has a lot of diode parts of the type HSCH-xxxx or HSCHxxxx.

The "SCH" in the part number seems to suggest a Schottky diode.

I looked on hp.com but because of an extension to Moore's law or something,
HP being a computer company, Firefox does not work with the hp.com search
box. So using quasi-advanced Google search
"qsch site:hp.com"
turned up nothing.
The schematic showed a zener symbol, but I later found the relevant parts
list page, and so reason for .35V diode-test diode drop. I'd never come
across 1N4148 type packaged schottkys before.
