M4

hongjiacheng · Diodes - General Purpose · SMA(DO-214AC)

M4 from hongjiacheng, in a SMA(DO-214AC). 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, the end marked with the cathode line; the M4 blocks 400 V repetitive peak reverse (280 V RMS) and passes 1.0 A average forward current.
2 A passive Anode terminal at the end opposite the cathode line; the M4 has a maximum forward voltage of 1.0 V at IF=1.0 A and a 30.0 A non-repetitive peak surge rating (8.3 ms half-sine).

  • Symbol: M4
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: m4-etched.step / m4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); m4.step / m4.glb are the bare package body.
