Transistors silicon KP303I analogue 2N3822 USSR 20 pcs

hi friends it is no secret that the leaders of the USSR loved gigantic project and this was expressed in everything and radio components were no exception this is the largest general-purpose transistor made in the USSR p210 it weighs about 30 grams the transistor is germanium with collector current 12 amps and the maximum power dissipated of sixty watts which is very good for its time and this is another transistor TK 235 - 32 based on them I did a powerful electronic load of 1.5 kilowatts they have unusual design for transistors collector current as much as 32 amps but in such a housing there are also more powerful transistors for example TK 235 - 63 it's for 63 amps this transistor can operate at frequencies up to 4 megahertz and have a gain of 8 to 100 the collector emitter voltage could reach 360 volts depending on the index yes the design is really interesting but there were even m
