MM1W5V1L

Shandong Jingdao Microelectronics · Zener Diodes · SOD-123FL

MM1W5V1L from Shandong Jingdao Microelectronics, in a SOD-123FL. 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 Cathode passive Cathode terminal of the Zener diode, per the PINNING table and the symbol on the outline drawing (pin 1 = cathode, pin 2 = anode).
2 Anode passive Anode terminal of the Zener diode, per the PINNING table and the symbol on the outline drawing (pin 2 = anode).

CAD (KiCad official)

  • Symbol: MM1W5V1L
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: mm1w5v1l-etched.step / mm1w5v1l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1w5v1l.step / mm1w5v1l.glb are the bare package body.
