    what is turn on time, turn off time , Delay time,storage time in case of a transistor..?

    and if this information is not given in the data sheet how we can find out max. switching speed of that transistor?
    like i have data sheet of BC807 transistor..

    link for its data sheet is

    You'd need to test samples of it in the circuit you intend to use it.

    That particular transistor has a transition frequency of 80MHz, which is kind of slow.

    If you put any transistor into deep saturation, it will take a lot longer to turn off than if you don't let it get deeply saturated.
