MM1Z3B3 from ST Semtech, 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, listed as pin 1 in the PINNING table for the SOD-123 package. The datasheet gives no electrical limits for this pin beyond the family ratings (500 mW power dissipation, 150 °C junction temperature). |
| 2 | Anode | passive | Anode terminal of the zener diode, listed as pin 2 in the PINNING table for the SOD-123 package. The datasheet gives no electrical limits for this pin beyond the family ratings (500 mW power dissipation, 150 °C junction temperature). |
