MMBZ5V6ALT3G 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; per the datasheet it is used with pin 3 for a unidirectional configuration, and the series has a standard Zener breakdown voltage range of 5.6 V to 47 V. |
| 2 | CATHODE 2 | passive | Cathode of the second Zener junction; per the datasheet it is used with pin 3 for a unidirectional configuration, and pins 1 and 2 together with pin 3 allow a single bidirectional configuration. |
| 3 | ANODE | passive | Common anode shared by both Zener junctions, so the dual common anode design protects two separate lines using only one package. |
