Now deep into sorting all my T0220 trannystors. I counted them beforehand... almost 200 of them, 192 IIRC.
Slow progress, have to spend time researching each and evry one of them, as none of them are familiar.
But, at least I get to learn lot of new part number, and specs I didn't even know existed.
The award of the shittest data sheet I have just awarded a second ago to Sanyo.
Have a 2SA1968 here. Datasheet says it's a NPN. I test it and the cinese meter says it's a ... PNP not NPN
How hard is it Sanyo to know your NPN from your PNP ? IF you design and make transistors, I would hope that it should be within the realm of possibilities, no ?
Luckily the data in the tables are unambiguous... they show negative Vce and Ic, as you always see with PNP transistors.
Also... I found two versions of their datasheet. One extremely old, horrible quality scan, which as this mistake, then anothr version of it, much more modern, clean native PDF file made on a computer.
It ALSO has the error ?!
Dear me....
Another good one was a datasheet that gave a peak collector current of 50mA and a sustained current of 10nA ! Yes NANO amp not mA !
You do need to keep your brain and common sense turned on when looking at these datasheet ......
Oh, and there are datasheet made by some "ISC" company, with a green logo. Run away from these datasheet if you can... they have only 2 pages when the OEM one had 12, and for BJT thy do NOT tell you on the first page (or anywhere !) what is the part number for the complementary type.... like pretty much any other datasheet would tell you right at the top of the first page
Think I have processed 45 transistors... 25% done. If I keep at it, maybe in 2 days I will be done.. just maybe.
