MM5Z33 from CBI, in a SOD-523. 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; the datasheet states no separate electrical limit for this pin beyond the family ratings (Ptot 200 mW, Tj/Tstg -65 to +150 °C). |
| 2 | Anode | passive | Anode terminal of the Zener diode; the datasheet states no separate electrical limit for this pin beyond the family ratings (Ptot 200 mW, Tj/Tstg -65 to +150 °C). |
