EFM104

LRC · Diodes - Fast Recovery Rectifiers · DO-214AC(SMA)

EFM104 from LRC, in a DO-214AC(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, marked by the color band on the DO-214AC package; EFM104 has VRRM 200 V and VRMS 140 V.
2 A passive Anode terminal; EFM104 handles 1.0 A average forward current at TA = 75°C and maximum DC blocking voltage of 200 V.

CAD (KiCad official)

  • Symbol: EFM104
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: efm104-etched.step / efm104-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); efm104.step / efm104.glb are the bare package body.
