BIPOLAR
A2
It does not stand for anything. It is a maker's designation mark, a throwback from the thermionic tube (valve) days. The letters in front of the number used to indicate the heater voltage and the type of internals (triode, pentode etc)
B used to indicate that it was a semiconductor, not a tube.
There are different designations around the world, for the same equivalent device, American, European and Japanese.
It is one junction i.e. P-N junction diode.
gunn diode is transfered electron device & PIN diode is semiconductor device
whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
Another diode with similar specifications.

It actually means Light Emitting Diode. I hoped i helped :)
