2SA733 / A733 PNP Transistor

2xa733 Highly unlikely to be of much relevance. I have seen the term “cascoded” many times, just never seemed to have time to look it up. Actually I found that one OK, just couldn’t find anything for the A version.

Then I heard another brief cut-out. OilmasterAug 2, Discussion in ‘ Solid State ‘ started by roger2Aug 1, In any case, a mystery is solved, and I have learned a few things here.

One channel was intermittent. When I say in series I mean that the collector of the 2saA connects directly to the emitter of the 2sa I actually had the datasheet for it on my PC. Yes, my password is: Inquiring minds want to know things.


But it has most things that are not too obscure. I’m sure it is not as good as those professional trade manuals that you have. They Kenwood did the same thing in the kr manual. I was looking all over the web for 2saA with no luck: I poked around for a few hours, and could find no reference to the meaning of the A suffix.

Here is L channel, R is almost the same: The reference is from both the parts list and schematic of Kenwood KR But I don’t see it on any of the A spec sheets. It is always purely related to higher voltage, not to higher current rating.

Your name or email address: The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa Working on a Kenwood KR receiver and suspect one of these of being bad.


ZOOM, I am asking what the “A” suffix for 2sa means because I want to dtasheet what type of part the designers had in mind for this position in the amp. The “A” suffix usually designates a higher voltage rating.

It is written just like in my OP.

what does (A) suffix mean in 2SA733 (A) (Q,P) ???

HyperionAug 2, ZOOMAug 2, Share This Page Tweet. The “A” suffix means new and improved. They both had “halo” cracks in their solder joints. 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.

JURB – Thanks for the detailed explanation of transistor designations. I checked DC voltages and found a dataeheet close match to what is shown on the schematic, slightly higher but everything in correct relative proportions. What does the A suffix mean?
