SOT05LC

XCH(旭昌辉) · IC · SOT-23

SOT05LC from XCH(旭昌辉), in a SOT-23. 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 1 passive Protected line 1 (steering-diode node, lower in the schematic), for a unidirectional line or one side of a bidirectional pair; working voltage 5V, 60W peak pulse power (8/20μs).
2 I/O 2 passive Protected line 2 (steering-diode node, upper in the schematic), for a unidirectional line or one side of a bidirectional pair; working voltage 5V, 60W peak pulse power (8/20μs).
3 COMMON passive Common node joined to the avalanche TVS diode in the schematic; it serves as the reference/ground return for two unidirectional lines, or as the protected line in single bidirectional use.

CAD (KiCad official)

  • Symbol: SOT05LC
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sot05lc-etched.step / sot05lc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sot05lc.step / sot05lc.glb are the bare package body.
