RR1LAM4STFTR

ROHM Semicon · Fast Recovery / High Efficiency Diodes · SOD-128

RR1LAM4STFTR from ROHM Semicon, in a SOD-128. 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 (pin (2) in the datasheet outline is marked Anode, pin (1) Cathode per the package drawing); rectifier with VRM 500 V, VR 400 V, Io 1 A.
2 A passive Anode of the rectifying diode; forward voltage 1.1 V max at IF=1A.

CAD (KiCad official)

  • Symbol: RR1LAM4STFTR
  • Footprint: Diode_SMD:D_SOD-128
  • 3D model: SOD-128 (KiCad packages3D, STEP)
  • 3D model files: rr1lam4stftr-etched.step / rr1lam4stftr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rr1lam4stftr.step / rr1lam4stftr.glb are the bare package body.
