MMBZ6V8A from JSMSEMI, 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 (unidirectional circuit tied to pins 1 and 3), with VBR 6.46 V min, 6.8 V nom, 7.14 V max at 1.0 mA and VRWM 4.5 V. |
| 2 | K2 | passive | Cathode of the second Zener TVS diode (unidirectional circuit tied to pins 2 and 3), with VBR 6.46 V min, 6.8 V nom, 7.14 V max at 1.0 mA and VRWM 4.5 V. |
| 3 | A | passive | Common anode of both Zener TVS diodes, shared by the pin 1 and pin 2 circuits; the two diodes can be used as two unidirectional channels or one bidirectional configuration. |
