Hi All,
I need a replacement for a BD155 transistor.
Can anyone suggest a replacement?
Thanks.

BD139 is close to. It depends on real power dissipation a bit, frequency range, case requirements (TO220 may possibly be used too), etc.
The voltage for the BD139 is OK but the power is only 12.5w.
I really wanted something with say 30 watts dissipation.

2SD669.
BD139, BD230, BD379, BD787, 2SC2690
TO126 case is up to 20W max (and that's too much for it). If you really need 20-30W case then possibly you need TO220 case?
