MMBZ16VALT1G from onsemi, in a SOT-23. 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 1 | passive | Cathode of the first Zener junction in the dual common-anode SOT-23 package; for unidirectional use the circuit is tied to Pins 1 and 3. |
| 2 | CATHODE 2 | passive | Cathode of the second Zener junction in the dual common-anode SOT-23 package; for unidirectional use the circuit is tied to Pins 2 and 3. |
| 3 | ANODE | passive | Common anode shared by both Zener junctions, allowing two separate unidirectional configurations or a single bidirectional configuration in one package. |
