MMSZ5262B_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 | Zener cathode terminal, shown as pin 1 in the SOD-123 outline; the datasheet gives no pin-specific voltage or current limit, only device ratings of 500 mW total power dissipation and -55 to +150 °C junction/storage temperature. |
| 2 | Anode | passive | Zener anode terminal, shown as pin 2 in the SOD-123 outline; the datasheet gives no pin-specific limit for this terminal. |
