The “A” suffix usually designates a higher voltage rating. Where did you come up with a 2SAA? No, create an account now.

When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa After the reflow it straightened up almost completely They Kenwood did the same thing in the kr manual. The reference is from both the parts list and schematic of Kenwood KR Working on a Kenwood KR receiver and suspect one of these of being bad. Just replace with ksa and call it a day. I have had a 2sa7333 around for this, trying to find references to the 2SAA as distinct from the 2SA and can’t find anything worthy of note.


Good to know about the existence of those Japanese transistor data books too. But I did take some live readings, they were pretty close to what the schematic datasheft. 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.

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.

It is written just like in my OP. I am hesitant to remove them because I have already reflowed once. But they are only using it as a current limiter, and my opinion is that it doesn’t mean anything, and 2sa73 just a glitch that got into their computer.

what does (A) suffix mean in 2SA (A) (Q,P) ??? | Audiokarma Home Audio Stereo Discussion Forums

I downloaded the 2SA data sheet but it does not mention the A. HyperionAug 2, Inquiring minds want to know things. Then I heard another brief cut-out. Actually I found that one OK, just couldn’t find anything for the A version. JURBAug 2, dataheet The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa What does the A suffix mean?

But it has most things that are not too obscure. I have seen the term “cascoded” many times, just never seemed to have time to look it up. 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. Log in or Sign up.

Is this transistor in a high gain position? It does show Q and P as being hfe ranges.

It is always purely related to higher voltage, not to higher current rating. My go to for older transistor or semi-conductor info is datasheetarchive.

Here is L channel, R is almost the same: 2aa733 “A” suffix means new and improved. Share This Page Tweet. They both had “halo” cracks in their solder joints. I appreciate the time you put into researching this.

I was able to get a look at one of them with a small lighted magnifier. Highly s2a733 to be of much relevance. Discussion in ‘ Solid State ‘ started by roger2Aug 1,
