US1MD

ST Semtech · Fast Recovery / High Efficiency Diodes · SMA

US1MD from ST Semtech, 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 terminal, marked by the color band on the SMA (DO-214AC) body; the US1MD blocks up to 1000 V DC (VRRM 1000 V) and conducts 1 A average forward current.
2 A passive Anode terminal at the end opposite the color band; the maximum forward voltage is 1.7 V at 1 A and the peak forward surge current is 30 A (8.3 ms half sine-wave).

  • Symbol: US1MD
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: us1md-etched.step / us1md-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us1md.step / us1md.glb are the bare package body.
