It looks like it is not a diode nor a transistor. bit sort of mix.
if you look at the picture  you see that one of the two legs is thinner.
And is described at the link as a transistor.

Interesting is that  the one in green color has  number 2 in front: 2tk235
But looking  identically  in silver color  doesn't tk235
The  second number looks like year of production: tk235-63- 25 but I'm not sure.

Ok I found  more  about it:

works up to 4MHz

4 MHz is the frequency at which the transistor has a gain of 1, that is, it simply conducts current.
I know similar characteristics of many Soviet transistors. "Transition frequency" of 4 MHz indicates that such a transistor is suitable only at low frequencies, a maximum of tens of kilohertz.
For example, KT8101A:
Transistors KT8101A silicon epitaxial-planar structures n-p-n universal.
Designed for use in the output stages of audio frequency amplifiers, voltage stabilizers, converters.
The cutoff frequency of the current transfer coefficient of the transistor for a circuit with a common emitter: not less than 10 MHz;

In those days, there were no powerful mosfet transistors or IGBT modules.  Therefore, not efficient bipolar transistors as this TKxxx or similar were produced for use in power supplies or switches.

AG
Not only on the outside surface of a wire but almost any material including supposed insulators as well. These video's show the basic electrical effects most of these FE inventors were using pretty well.

As we can clearly see these kinds of electrical effects are very different than what most people are used to. As Tesla implied this is a surface effect and the conductors can be hollow and paper thin or as small as a human hair lighting large lights. Obviously this kind of electrical energy is not low voltage or low frequency as some suggest, that's nonsense.

AC

It creates its' own path, this can also be done without a physical material
