I can only find in Mouser the transistor BU508AF. It does not have a free-wheeling diode! Will it be a problem to put this one? Since these transistor is also suitable to a High voltage NPN power transistor for standard definition CRT display?

I found also this one: FJAF6810DTU. Will it work?
Does the value of the resistance between Base-emitter influence the performance of the transistor?
