Identifying TO-3 transistor pins?

How do I differentiate between the E and B pins of a TO-3 case power transistor? 2N3055 if I remember correctly. Thanks.

--- You go to

and you type in "2N3055".

Then you click on the hits you get back until you find what you want.

This might even be the first one that comes up:

I believe the "standard" is:

Hold device so a line _between_ the pins is horizontal, and that line is above the center-line of the package, then read, left-to-right, B-E

How do I differentiate between the FIVE copies of your post I've received time stamped between 20:38 and 20:53?

Ruling out referring to the time-stamp as too easy, did he use different coloured inks?

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.

Perhaps you should send a complaint to snipped-for-privacy@google.com? Maybe they know how to tell all these posts apart. ;-)

Mark,

You type "2N3055" into Google search and look over the results. Choose one that seems OK and you'll get more useful information as well as the pin out. ......i.e.:

Ken

Click on the link.

How did you manage to get a 2955 datasheet when you googled 3055 ?

Just curious.

Graham

p.s. The OP could even go to onsemi.com and get the genuine 'motorola' data sheet.

ROTFLMAO!
