MSUSBLC6-2SC6

MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-23-6

MSUSBLC6-2SC6 from MSKSEMI, in a SOT-23-6. 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/O1 passive ESD-protected high-speed I/O channel 1, internally tied to pin 6 in the graphic symbol, with 0.8pF typ I/O-to-GND capacitance and 5.0V max reverse working voltage.
2 GND power_in Ground reference for the ESD protection diodes.
3 I/O2 passive ESD-protected high-speed I/O channel 2, internally tied to pin 4 in the graphic symbol, with 0.8pF typ I/O-to-GND capacitance and 5.0V max reverse working voltage.
4 I/O2 passive ESD-protected high-speed I/O channel 2, internally tied to pin 3 in the graphic symbol, with IEC 61000-4-2 protection of ±30kV air and contact.
5 VBUS power_in Supply/VBUS rail connection of the diode array (labelled VDD in the electrical table), with clamping voltage of 11.0V typ, 13.0V max at IPP=8A, 8/20μs.
6 I/O1 passive ESD-protected high-speed I/O channel 1, internally tied to pin 1 in the graphic symbol, with IEC 61000-4-2 protection of ±30kV air and contact.
