[Milsurplus] Smart People: 2SD882 = 12V, What = 24V?

[don davis]

Try BUL216 or similar family.  This is ST preferred type for high voltage
use and seems to go for about a buck or so.  Looks like freq is OK, may need
drive tweaked.  There are literally thousands to pick from, I'd stick with
modern power converter types to be used off of 240 volt lines directly -
these will be rated for many 100's of volts.  Other critical parameter is
max freq / storage time / transition time.

Smart People: 
This is boatanchor related; honest.

2SD882 works well in low-power transmitter PAs with Vcc of 12 volts.  Vceo
max is 30 Volts.
Data sheet is at:

Can someone suggest a device with similar gain that one could use in a
similar circuit with a Vcc of 24-28 Volts?
