MMSZ5258BS_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 | Cathode end of the zener diode, identified by the color band on the package; the datasheet rates the device at 200 mW power dissipation at TA=25°C (Note A) with a junction and storage range of -55 to +150°C. |
| 2 | Anode | passive | Anode end of the zener diode, the terminal opposite the color-banded cathode end. |
