MMSZ5251A_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 zener diode, marked as the polarity reference on the SOD-123 diagram; the datasheet gives no pin-specific electrical limits beyond the device ratings. |
| 2 | Anode | passive | Anode terminal of the zener diode, opposite the cathode per the SOD-123 diagram; the datasheet gives no pin-specific electrical limits beyond the device ratings. |
