MMSZ5250BS_R1_00001 from PANJIT International, in a SOD-323. 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 | The cathode is the end marked by the color band on the SOD-323 package, per the datasheet's polarity note. |
| 2 | Anode | passive | The anode is the unbanded end of the SOD-323 package opposite the cathode band, and the datasheet gives no separate electrical limit for this pin. |
