MMBZ5232BW-7-F from Diodes Incorporated, in a SOT-323. 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 | A | passive | Zener anode, the bottom-left terminal in the device schematic. |
| 2 | NC | unconnected | No internal connection; the bottom-right terminal in the device schematic is drawn without a connection to the diode. |
| 3 | K | passive | Zener cathode, the single top terminal in the device schematic; the 5.6V Zener (MMBZ5232BW, marking KE2) has a Zener voltage of 5.32V to 5.88V at 20mA. |
