I'm after a datasheet for a BY409 diode (and a BY406).

I've found plenty of datasheets for the BY401, 2, 3, and 4. The scanned datasheet stops there :-(

Any help appreciated

Looking at my 2003 vintage "World transistors, diodes, thyristors & ICs" it claims a BY409 is a 12.5kV 2.5mA silicon diode. It suggests a BY406 is 350V 0.8A.

These old paper books come in useful for something!

Hello,

I found an interesting table in the 1981 mullard book about the EHT diodes:
