MMSZ5232A_R1_00001 from PANJIT International, 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 surface-mount silicon Zener diode, labeled pin 1 ('Cathode') in the SOD-123 package diagram; polarity is set by this marking, and the device is rated 500 mW maximum power dissipation at TA=25°C (Note A). |
| 2 | Anode | passive | Anode terminal of the Zener diode, labeled pin 2 ('Anode') in the SOD-123 package diagram, opposite the cathode for reverse-biased Zener regulation. |
