NJL0281 and NJL0302

[sparkle]

where to find them...
digikey has a limit of minimum 25 pieces... it is to much for me.... Also Onsemi will not send to Croatia....
is there any other source for those transistors...?
thanks in advance

Zdravo !

I've made a quick look around the web, so the results of my search are not good for you :

Elfa -> NO
Dalbani -> NO
Farnell -> NO
Rapid -> NO

Sorry.

Zdravo to You too.... nice....

that is what i am talking about...hard to find.... only digikey and onsemi directly and neither of them is suitable for me... and i would like to use those two transistors better than anything - because i have allready finished project from Roender and no need to modify it.......the boards are very nice and clean ....

Why not use the NJL3281D and NJL1302D? Shouldn't have to buy 25 of them.

"because of Cob (400pF vs 600pF) and linearity".....

that is why i would like to find these two guys instead of anything else....

You could use, without much worries, NJL3281/1302 if you can't find the "zero" version.

o.k. - thanks

this i can find on digikey.....

I'm not so sure that this is real or just an error in the data sheet. I believe that both parts use the same die inside and the only difference is the size of the package. One has the larger TO-264 package and the other has the smaller TO-247 package.

interesting......thnx for the info

Mr. Hansen,

Both parts use the same TO-246, 5 lead case 340AA but the chip inside is very different ... only the thermal track diode is the same.

I've try both njl3281/1302 and njl0281/0302 in my amp. The "zero"version sound more smooth, more precise on highs, with no harshiness or sibilance. There is nothing wrong with the other version (3281/1302), but I prefer the "zero" version.
This is the schematic.

Regarding an old discussion about thermal stabilization method, it is not so difficult to implement a very simple method once you know the TC of the diodes and have all output stage transistors, including drivers and predrivers, on the same heatsink
