In comparing these two On Semi devices they are basically the same except the 21196 offers a tad more SOA than the other. The other specs on the MJ21194 however look more cohesive to me as compared to the specs on the MJ21196. Has anyone else on here ever bothered to look into which is the preferred output device? My rails are +/- 100 volts in this project.

If I recall correctly, the MJ21193 was originally a 200V and 200W device back when it was still produced by Motorola. The MJ21195 was the new improved 250W version. Now the MJ21193 has been improved to the same spec. I don't have the old datasheets around any more to verify this though.
Has anyone else noticed that the MJ21193/4 have better hfe at low Vce than the MJ21195/6?

I only have a small signal Motorola book left, thru out the power book and all the rest.
I remember we had a room full of data books and we threw them all out when we moved our lab. Must have had 20 of those big blue garage carts filled.
I guess at one time I noticed these differences. part has been around for a while, i have a rev4 d/s, I see it is at rev6 now. There is not that much difference in these parts, makes you wonder why they offer both types?
They could not even match the SOA curves with pulse readings for mj211913/4. Supposed to conclude that they are the same.
maybe that is why I have them on my list to get some.
I was thinking I should get a few sets before they go obsolete and use them in my old sx-950, replace the Mj15003/4 that i put in there years back now.
I can confirm that the sx-950 amp can drive a couple sets of speakers in parallel, my 8 ohm 15" woofer floors and the 4ohm Dynaudios gemini's. It is clear and loud 🙂
We blew the original toshiba's o/p's quiet a few times. The mj15003/4 survived the test.
have you ever performed the thd test as they show in fig 17? One way to match devices.

I have my old Motorola Power data book but why is it needed these are the OnSemi version?
As someone pointed out earlier in the thread the MJ21193/4 started out as lower voltage parts and were probably optimized for that. Their increased voltage rating probably
just came for free by being produced on a newer fab line - I'm completely guessing here.
The MJ21195/6 were probably optimized from the start as a higher voltage part and some
parameters suffered to meet the specs - again just a guess.
Anyone know for sure?
