MMBZ15VA from Shikues, 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 | K1 | passive | Cathode of the first Zener TVS diode, used as a unidirectional channel with pin 3 (common anode); MMBZ15VA has VRWM 12 V and VBR 14.25 to 15.75 V at 1.0 mA. |
| 2 | K2 | passive | Cathode of the second Zener TVS diode, used as a unidirectional channel with pin 3 (common anode); MMBZ15VA has VRWM 12 V and VBR 14.25 to 15.75 V at 1.0 mA. |
| 3 | A | passive | Common anode of the dual Zener TVS; circuit is tied to pins 1 and 3 or pins 2 and 3, or pins 1 and 2 for a single bidirectional configuration. |
