content: Oh god...FWIW, the conventional pinout is consistent with IPC, and this one is clearly not. There are standards!So... didja catch this one before sending it out, or after?Tim

content: Quote from: T3sl4co1l on September 27, 2018, 04:13:54 pmOh, before. This one was not exactly hard to catch. But seriously: why?? Why would you do that? Even if you don't care about standards, Google it for 2 seconds and pronto... And back in the day, take any databook of the shelf and they will pretty much all have it different.Djeeezzz..

content: This part identifies as a clockwise pin numbering. Didn't you know there are many different genders of pin numbering? Are you biased against this part's personal choice? It's very regressive of you to assume pin numbering rigor is a valid point of view. You must immediately alter your terminology choices to be pin-numbering order neutral.Seriously though, WTF?Is there any date on the datasheet and is it April 1st?

content: The data sheet has lots of fun in it. The typical application circuit has managed to have almost zero information. And the part has a power dissipation of 300 plus mW, but max current, forward or reverse of 25 mA. Since it is a 3.3 V zener it is hard to see how it gets more than a little over 80 mW.Now you see what the new hires from the bottom of the barrel are assigned to do.
