BJTs for VAS Stages

The Toshibas parts are less desirable in my case since I would probably have to buy a whole reel if SMT. Fairchild & ONSemi are good choices for Americans since Mouser and DigiKey carry these lines.

Have you looked the MJD44H11 - MJD45H11 of ONsemi?

thanks, fotios
I look into it. I be back.

Lineup, regars

edit:
The spice models for Onsemi MJD44H11 (npn) and also for MJD45H11 (pnp)
can be downloaded from this page:

( .sp3 is the Level 3 .. sometimes not different from Level 1 )
thanks again

Hi Lineup, glad to meet you again after long time

These devices offered from ONsemi in two versions: MJD44-45H11 in D-Pack (in reel as prefer danville) and D44-D45H11 in TO-220 package. They are great devices with Vce=80V, Ic=8Amax, Pd=20W, ft=50MHz, hFE=250-350 for Ic=1A, the only drawback??? it is the Cob=130-230pF. I have implemented and checked those in two of my projects and their behaviour proved excellent.
The most important it is that we can obtain either of the two versions very easy. For Europe from Farnell and for USA from Digikey, in very low prices.

Regards
Fotios

yes.
absolutely.
BD139/140 are also 80 Volt devices.
Here we have a very good alternative to try.
I guess with a great deal of performance improvements.
As far I I can see, from a quick look at the curves in datasheet.

PS.
Did you know, my friend,
that under the Junta military occupation of your country, Hellas
while sweden in the regime of Olof Palme
Mikis Theodorakis & Melina Mercoury often visited Sweden with musical conserts, under exile form home country,
for the support of renewal Democracy in Greece.
Finally was a success, after many & much sufferings from Ellas brave activists.
Today, Grekland is a better land, with fair elections to Governments
