Hi all.
Looking for which transistors could match the requierements:
NPN
Vce between 99 and 200 V
Ic between 499 mA and 1 A
Ft between 49 and 180 MHz
TO220 if possible
No matter if low gain, it is only to linearly invert (gain 1) a 25 Vpp sawtooth signal riding on top of 50 Vdc as common emitter amplifier buffer.
If anyone has a spare to sell, or trade with whatever you need, fine.
A simulation on a simple Multisim works fine when chosing an 'ideal' transistor, but does not perforn selecting a couple of candidates in its humble library.
