Shandong Jingdao Microelectronics · Zener Diodes · SOD-123
MM1W4V7 from Shandong Jingdao Microelectronics, in a SOD-123. 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; the datasheet's pinning table lists pin 1 only as Cathode and states no separate electrical limit for this pin. |
| 2 | Anode | passive | Anode terminal of the zener diode; the datasheet's pinning table lists pin 2 only as Anode and states no separate electrical limit for this pin. |
