information required about "NEC D882 transistor" and "BD243C"?

i need help and instructinos about "NEC D882 transistor" and "BD243C transistor" i want to use it in inverter for florescent lamps..
tell me the other equivelent transistori can use....
the maximum volt and current we can give to these transistors....

thanks

data sheet for 2SD882 here;

2SD882 pdf, 2SD882 description, 2SD882 datasheets, 2SD882 view ::: ALLDATASHEET :::

BD243C here:

I used Google by the way....If you need lessons on how to use it see me after class

i am not fully understand with datasheets.....
kindly tell me other components which are equivalent to these transistors, because these transistors are not available in our market
