EM520S

XCH(旭昌辉) · IC · SMA

EM520S from XCH(旭昌辉), in a SMA. 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 K passive Cathode end, marked by the color band on the package; the diode blocks up to VRRM 2000 V and conducts 1.0 A average forward current.
2 A passive Anode end, opposite the color band; forward voltage is 1.10 V maximum at IF=1.0 A.

CAD (KiCad official)

  • Symbol: EM520S
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: em520s-etched.step / em520s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); em520s.step / em520s.glb are the bare package body.
