Soviet diodes

Notes on nomenclature:

• The actual model numbers use the Cyrillic alphabet (e.g. Д for D, or КД for KD)
• For improved versions of older diodes, the letter M was added at the beginning of the model number (e.g. MD if derived from D). These improved diodes are sorted here under the original model (D).
• Military versions of diodes (e.g. extended temperature range and reliability) have the numbers 1, 2, or 3 instead of the letters G, K, or A, respectively, at the beginning. Here 2D diodes are categorized under KD, etc.
• For newer devices, the letter S (С for сборка) as the third letter indicates multiple diodes in one package.
