MMBZ9V1A 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 | 1 | passive | Cathode 1 of dual transient voltage suppressor providing unidirectional ESD protection with Pin 3 (common anode), with breakdown voltage 8.65-9.56V and clamping voltage of 14V at 1.7A peak pulse current. |
| 2 | 2 | passive | Cathode 2 of dual transient voltage suppressor providing unidirectional ESD protection with Pin 3 (common anode), with breakdown voltage 8.65-9.56V and clamping voltage of 14V at 1.7A peak pulse current. |
| 3 | 3 | power_in | Common Anode connection shared by both transient voltage suppressor diodes, providing the return path for both unidirectional protection circuits (Pins 1-3 and Pins 2-3). |
