What gives?
In both countries they drive on the same side so that would not be an excuse.

As far as I can tell, every possible 3-pin (SOT23 topology) and 4-pin (SOT143 type) pinout has been mapped into every possible transistor connection.
We have some NEC SOT143s that are not just reversed, the pin1 dot is on the bottom.

Infineon is right, NXP is wrong ;-)
Do they transpose the pin numbers of similar components too, or are they
100% screwed up?Tim

Hey, I haven't been able to access the nxp website for days. Does that link work for everyone else? (Thread drift... sorry Joerg.) George H.
Similar here but at least the NXP devices fit Infineon's footprint. In the 80's it was worse. Philips had an n-channel FET, forgot the part number. Siemens offered one with the same number except that it was a p-channel.

Not 100%, at least they are interchangeable. MMICs are opposite with collector and base, unfortunately. Beats me why. In fast pulsers it would be nice to have them interchangeable in case a BJT doesn't perform or goes unobtanium.

I remember that one. Was it a 4416?

No, it was a European part number, B-something. But I don't remember and didn't keep the Siemens databooks. I generally preferred Philips parts.

It started with SC61/SOT143/TO253 and SC61A/SOT143R/SOT24. The reverse/A version was the only kind Toshia ever produced, but rival NEC did it in both flavours, long before Europeans got involved.

It works for me.
Use this site if you can't reach a website you want:
I was having a lot of problems, till I changed my DNS server to Open DNS
Open DNS servers:
208.67.222.222 Main 208.67.220.220 Secondary-- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.
When was that? I have lived and worked in Europe. Right out of the chute I started designing in SMT-only back in the mid-80's, our company was an early adopter. A lot of the transistors, diodes and stuff came from Philips/Valvo and Siemens.

Semiconductor fab has been off-shore-oriented since before then, but SC-61 was Toshiba commodity in consumer products by the end of the
80's. Their drawings had a strange projection which look like a bottom view above a side view, but wasn't. So who was on first?There were a number of unregistered 'leadless' parts that preceded sc59 or sc61 - one with four fold-under connections, two of which were wider, on one side, than the others.
RL
I've stuck a drawing up on A.B.S.E. of the unregistered predecessor to the SC61A.

Mechanical engineers are compulsive about symmetry, which allows parts to be put in wrong, two or four different ways. DIP14 packages should never have been symmetric.
I have an optical assembly here that has indexing pins that align two sections rotationally before they can be bolted together. They engage at eight different positions, one of which is correct.

Bulk optics stuff is the same way. It's common to find lens elements that are nearly, but not quite, symmetrical, and which can be assembled backwards with no obvious problem...until final test.

Great book, "The Hubble Wars", in which one mis-assembled test fixture has a starring role.

ABSE is rarely used these days. Most people put images up on web sites, or photo sites, or Dropbox. It's mainly Jim's rants about broken furniture.

Hey Michael, Thanks for that! Everyone here just says it's the website that is down. My response of, "It's a huge f-ing semiconductor site, it's not going to be down for weeks!" falls on deaf ears.
Maybe I can get some action.
