Good to know about the existence of those Japanese transistor data books too. My go to for older transistor or semi-conductor info is datasheetarchive.

But it has most things that are not too obscure. JURB – Thanks for the detailed explanation of transistor designations. HyperionAug 2, If you really need to replace it, just make sure that the voltage between C-B doesn’t exceed 60V, and between C-E doesn’t exceed 50V. 2xa733 did you come up with a 2SAA?

OilmasterAug 2, I have had a look around for this, trying to find references to the 2SAA as distinct from the 2SA and can’t find anything worthy of note. But I don’t see it on any of the A spec sheets. Also, there is no 2scA, just 2sc which is the normal complement of 2sa Then I 22sa733 another brief cut-out. ZOOM, I am asking what the “A” suffix for datashedt means because I want to know what type of part the designers had in mind for this position in the amp.
I was looking all over the web for 2saA with no luck: I appreciate the datasheeet you put into researching this. Inquiring minds want to know things. The two transistors being datasheeet are Q15, the 2sa Aand Q17, the 2sa Thanks again to all Do you already have an account? I poked around for a few hours, and could find no reference to the meaning of the A suffix. I was able to get a look at one of them with a small lighted magnifier.
It is always purely related to higher voltage, not to higher current rating.
They both had “halo” cracks in their solder joints. JURB – thanks for taking the time to type in those specs for the non-A 2sa Turns out there was a 2scA, at least briefly. I have seen the term “cascoded” 2xa733 times, just never seemed to have time to look it up. They are also in series?
What does the A suffix mean? I am hesitant to remove them because I have already reflowed once.
It is written just like in my OP. After the reflow it straightened up almost completely But they are only using it as a current limiter, and my opinion is that it doesn’t mean anything, and is just a glitch that got into their computer. Here is L channel, R is almost the same: One channel was intermittent. Actually I found that one OK, just couldn’t find anything for the A version. The “A” suffix usually designates a higher voltage rating. The reference is from both the parts list and schematic of Kenwood KR Here is the left channel of KR You must log in or sign up to reply here.
I’m sure it is not as good as those professional trade manuals that you have. Working on a Kenwood KR receiver and suspect one of these of being bad. As you pointed out, 2sc is the complement to 2sa, so I would assume that the “A” version of 2sa has similarly increased temperature ratings. Highly unlikely to be of much relevance. Your name or email address: I downloaded the 2SA data sheet but it does not mention the A.

Share This Page Tweet. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa Just datqsheet with ksa and call it a day. The “A” suffix means new and improved. Discussion in ‘ Solid State ‘ started by roger2Aug 1, Yes, my password is: I checked DC voltages and found a fairly close match to what is shown on the schematic, slightly higher but everything in correct relative proportions.
