switching transistor basic question

[Prototyp_V1.0]

Hi.

Some transistors is called "switching transistor" (I call it just swt hereby) in datasheet. That means they are obviously designed to be used in switching applications.
But, exept from that turn off and turn on time - Is there any difference between swt and other transistors? Unless practical considerations like casing and lack of an complementary of course.

Is there any reason not to use a swt in an analog amplifier circuit?

Does an awt transistors having some characteristic that mane it less nusable to other applications like audio amplifiers etc?


Have never seen any question alike on the net, so I just had to ask

I too havent come across the so said switching transistors.
What i beleive was that the transstors are biased in such a way that they are used as a switch or an amplifier and so on.

and curious to know about it more.

Saturation recovery time is the primary attribute, that
and a semi-decent Hfe. By today's standards of data rate
they are not likely to be desirable for logic paths. Not
as saturating switches (see 50-100nS Trr, 5-10MHz, woo-hoo!).
But they may actually be more forgiving when pushed into
light or near saturation, than "analog" transistors.

I too have not come across tern switching transistors.

I am curious to noe more about it...
