Add pkg SOT23-3P95_280X145L60X40

[ubruhin]

SUMMARY

Copied from SOT23-6P95_280X145L60X40 and removed 3 pins. New 3D model from LibrePCB/librepcb-parts-generator#123

Not to be confused with the already existing, very similar "SOT23-3P95_230X110L50X40" package - they differ in body width & lead span.

DATASHEETS / REFERENCES

Not required, SOT23-6 was already drawn according JEDEC specs.

OPEN QUESTIONS / UNRESOLVED ISSUES

None

• I have read and followed the library conventions¹.
• For packages, I followed IPC7351C (see details in library conventions).
• For modified elements, I bumped their version number².
• I already used the new library elements in a design and verified their correctness (optional).
• I'm the copyright owner of the added content (i.e. the changes are made by myself, not copied/imported from somewhere else).
• I agree to publish all my changes under the CC0 Public Domain License³, allowing everyone to use and modify the content without any restrictions.

¹ Library Conventions: https://docs.librepcb.org/#libraryconventions
² Minor version bump if only metadata was modified (e.g. "0.1" -> "0.1.1"), major version bump if functional changes were made (e.g. "0.1" -> "0.2")

The SOT-23-5 3D-model has a pin1-dot:

It seems to be missing for the two SOT-23-3 packages though. Is that on purpose?

(And, a small detail: SOT23-3P95_230X110L50X40 has 0.15mm silkscreen lines, while 3P95_280X145L60X40 has 0.2mm silkscreen lines.)

Yeah that's on purpose because AFAIK most real SOT-23-3 packages do not have such a dot, while the higher pin count packages have it (though I guess there are exceptions). This was already reflected by the footprints so I kept this behavior for the 3D models for consistency with the documentation layer.

True, this is just for historic reasons 🙈 All SOT23-3..6 are consistent but the other SOT23 package has been created independently...
