Added a symbol for the BAV756S, which is a chip with 4 diodes, 2 common Anode, 2 common cathode


datasheet

  • Ensure that the associated footprints match the official footprint library
  • Check the output of the Travis automated check scripts - fix any errors as required

It is desirable that you provide in the text both the data sheet link and a screen shot of the symbol showing the pin types etc.

something like this, then it is much easier and faster to give feedback

If so, then you can get the following feedback back rather quickly

Move the "Package_TO_SOT_SMD:SOT-363_SC-70-6" to just beneath the symbol, it is placed to far away

Change the description
"Quad diode package with one pair CA and one pair CC"
into
"Quad diode package with one pair CA and one pair CC, SOT323/SC-70"

Change the foot print filter to
SOT?363?SC?70?6*

Thank you, yes that makes a lot of sense :)

The diodes should be "open" (unfilled) with a line in the middle like IEC shows and other diodes in our library.

I often find these dual diodes don't go on circuit right next to each other. What about making this a dual-unit symbol and copying the existing CA/CC diode symbol?

Edit: The description should have 363 and not 323.

Also, I would say the footprint filter could be SOT?323* since that will give the greatest flexibility if those footprints are ever split for some reason and it retains only the footprint name used by Nexperia.

There we go. Made the symbol into a 2 unit symbol. and changed the filter back to the more generic filter.

I decided to center the diodes based on their pin positions, I don't know if I'd prefer the diode with the 2 horizontal pins on Y0, but I'll leave that up to you :)

This symbol type, like the existing generic diodes, is preferred.

  • There should be a line through the middle of the diode symbols.
  • Change description to High-speed switching diodes, dual common anode/common cathode, SOT-363.
  • Pin name offset to 1mil.
  • Remove underscore in pin names.

  • What about pins names of A1, K2, CA, K3, A4, and CK. That would change pin names for pins 3 and 6.
  • What about this symbol (removing overlapping lines, use common graphical elements where possible, all pin lengths to 100mil, and add junction dot):

Visually this is fine. Probably many of our diodes can be updated later. Thanks!
