I am looking for a Bipolar transistor that is rated for at least 150vdc can handle 2.5watts with a gain of 100min.
I have looked at several of the usuals but it seems something with High VDC and a gain of 100 is a hard thing to do? I have found a couple but there 40+ watt devices in TO-220 cases and i am trying to keep the size small.
This is for a Switching application that will see variable DC with peaks as high as 130Vdc.
a TO-39 was about as big as i was hoping to see. smaller if possible.

Can you make a FET work in your application?
Make is your maximum current?
Do you have a rough idea of power dissipation?

I cant use fets as when the device is in low power mode. there inst enough voltage to turn on the gate of a fet. In low power mode the device triggers at 4v and we loose a little bit through the bridge and other components so there inst quite enough at the first switch to turn a Fet fully on.
The device will see pulses of 2.6 Watts @ 130V in full power mode.
I just recieved the hand drawn schematic last night. I will get it into proper format and see if i can get it posted here.
The 2SC4613 looks like a good candidate if its a currently available part.

If 2SC4613 is ok...
May I suggest :
2SC3902
2SC3787
2SA1769
2SA1507
2SA1477
2SC3117
2SC3116
2SC2911
2SA1249
2SA1248
2SA1209
I found transistors in FLP and TP packages, but I guess you don't want those ?

Thanks Simon5 those all look very nice. and i like the insulated tab. on these. Plenty of options there to see what i can get. Excellent!
Thank you!
