Rework USBLC6-2 and -4 ESD protectors
A different attempt at reworking the USBLC6-2 ESD protectors, also including the -4 variant. See also !4070 (closed) and !4085 (closed).
Before:
After:
-2
The main differences:
- substantially smaller
- straight-through wiring
This allows quite dense layout (yes, I know it's actually not a USB3-compatible part!)
The diodes are small, but they're quire legible even when printed physically:
-4
The -4 is also reworked to allow same-side wiring (though it's not a wire-through part):
or user may choose this way:
KLC violations
- S3.1 centering - there's an even number of pins at 0.1" spacing
- S4.4 GND is passive - seems normal for ESD arrays
Parts changed
- USBLC6-2P6 - reworked
- USBLC6-2SC6 - made a derivative - has same pinning as -2P6
- USBLC6-4SC6 - reworked
