USBLC6-2 USB ESD protection

  • USBLC6-2SC6 is SOT-23-6 (LCSC C7519, JLC basic-friendly); USBLC6-2P6 is SOT-666 (much smaller). Same pinout and symbol body: 1/6 and 3/4 are the data pairs, 2 GND, 5 VBUS.
  • Library: EmbeddedEra:USBLC6-2SC6 (IPN EE-C-0146) extends USBLC6-2P6 (EE-C-0128). Pick the symbol for the package you place; never change a placed symbol's footprint to switch packages, because the IPN then names the wrong part.
