Datasheet «2SA733»

On 2da733 face it says: I poked around for a few hours, and could find no reference to the meaning of the A suffix. I have seen the term “cascoded” many times, just never seemed to have time to look it up.

The “A” suffix means new and improved. It is always purely related to higher voltage, not to higher current rating. Do you already have an account?

Yes, my password is: It is written just like in my OP. Inquiring minds want to know things. HyperionRatasheet 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. Log in or Sign up. They both had “halo” cracks in their solder joints.

I’m sure it is not as good as those professional trade manuals that you have. I can’t see the faces of actual parts well enough to read.

I was able to get a look at one of them with a small lighted magnifier. I downloaded the 2SA data sheet but it does not mention the A. Discussion in ‘ Solid State ‘ started by roger2Aug 1, 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 shows. Thanks again to all In several previous repair jobs, I failed to find the datasheets of such A version though. The “A” suffix usually designates a higher voltage rating. But it has most things that are not too obscure. datashest

JURB – thanks for taking the time to type in those specs for the non-A 2sa My go to for older transistor or semi-conductor info is datasheetarchive. You must log in or sign up to reply here. They are also in series?


The two transistors being discussed are Q15, the 2sa Aand Q17, the 2sa 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. I appreciate the time you put into researching this. Here is L channel, R is almost the same: Highly unlikely to be of much relevance.

ZOOMAug 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. Turns out there was a 2scA, at least briefly.

JURB – Thanks for the detailed explanation of transistor designations. After the reflow it straightened up almost completely But I don’t see it on any of the A spec sheets. Your name or email address: Is this the VAS, or some other stage?
