FOSAN · Zener Diodes · SOD-123
MM1Z39 from FOSAN, 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 | K | passive | Cathode (marked − in the internal configuration diagram); the Zener reverse-breakdown side, VZ 37 V min to 41 V max (39 V nominal) at IZT = 2 mA for MM1Z39. |
| 2 | A | passive | Anode (marked + in the internal configuration diagram); forward voltage VF is 0.9 V max at IF = 10 mA, and power dissipation is 500 mW max at Ta = 25 °C. |
