LC03-6.TBT

SEMTECH · TVS · SO-8

LC03-6.TBT from SEMTECH, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I/O line A (end 1) bidirectional Data line input/output that the signal enters at, protected by the internal TVS and rectifier bridge against surges up to 100A (8/20µs) per the datasheet's T3/E3 and STS-1 connection example.
2 GND power_in Ground pin that should be connected directly to a ground plane for best results, and is left unconnected in differential-only protection.
3 GND power_in Ground pin that should be connected directly to a ground plane for best results, and is left unconnected in differential-only protection.
4 I/O line B (end 1) bidirectional Data line input/output connection listed for the pin 4 and 5 pair; the datasheet also uses pins 4 and 5 as the ground connection in the T3/E3 and STS-1 configuration.
5 I/O line B (end 2) bidirectional Data line input/output connection listed for the pin 4 and 5 pair; the datasheet also uses pins 4 and 5 as the ground connection in the T3/E3 and STS-1 configuration.
6 GND power_in Ground pin that should be connected directly to a ground plane for best results, and is left unconnected in differential-only protection.
7 GND power_in Ground pin that should be connected directly to a ground plane for best results, and is left unconnected in differential-only protection.
8 I/O line A (end 2) bidirectional Data line input/output where the signal exits, forming the other end of the pin 1 line protected by the device.
