It would help if you would post the link to the photo.

Hello Petrus,
Can't see it on abse.

Placed a photo on
petrus bitbyter
I have located the pic on abse. The logo looks similar to Diotec
Possibly Diotec may have produced this type at some time or the 3402 is an oem part number, or if we take the conspiracy path, some scam manaufacturer is using a close copy of the Diotec logo.
If the device is in fact a 2N3402 it is now obsolete. Fairchild give a cross for the 2N3402 as 2N3393
I don't think it's Diotec. I came across this company recently, and their logo looks exactly like the photo, which is different from Diotec's logo. Unfortunately I haven't been able to remember the name of the company. I'm pretty sure I have one of their datasheets in my computer, but haven't been able to find it. Yet.

I'll take a guess that 3402 is the date code.
We need someone to identify the maker's logo.
What did it come out of btw ? Any guide to likely function ?

Just a guess: possibly a 1A 60V Triac or SCR?

Sanyo make a 2SC3402 which is an NPN transistor with integral bias resistors in the base and base-emmiter.
But not sure that's what you have.

What did it come out of? Some of these things are very low power thyristors or triacs from Taiwan or Korea.

3402 is the date code. It was made in the 34th week of 2002. "1A60" is the part number, which sounds very much like a 1A, 60V SCR or triac.

How do you know? Did your Mother tell you?

In another dept at work, they have a sign over their sink that says, "Your mother doesn't work here, so CLEAN UP THE MESS".
I kid the lady there about how the sign ls lying, because her mom _does_ work there, in _our_ department!
And to beat everything, her _brother_ also works in their dept! Talk about nepotism!
But, but.. A Moebius strip does have two sides...
If you count the edge.. ;-)

I Googled "semiconductor logo finder" , because I remembered that my old IC Masters had logo finders. Hit #1 took me here:
Page 3 shows the 'S' logo, and it is identified as SemiWell Semiconductor:
Once there I found this:
Mystery solved.
Hit #2 led to a more complete IC logo finder:

Rich, This seems odd. I see parts all day long. It's suppose to be 'Year' 'Week' , ex. 1989 , 23rd week of year = 8923. Not the other way around. For 2002 and 34th week = 0234. When was the date code designation changed? What body of standards regulation specified the change?

Thanks Greg. That's what I was looking for. Googled some time around, found a bunch of logos but not the right one. Matter of search string of course.
Also wish to thank all the others that tried to help.

I agree. But it is what Rich said, apart from being a 600 V device rather than 60 V.

A lot of conjecture and nonsense going on. Get the datasheet from the manufacture. Get solid proof that data code definition has changed. regards EN
