BZX84B13-7-F from Diodes Incorporated, 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 | A | passive | Anode of the zener diode, shown in the device schematic on the bottom-left terminal. |
| 2 | NC | unconnected | No internal connection; the device schematic shows the bottom-right terminal with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, shown in the device schematic on the single top terminal; the VZ for BZX84B13 is 12.7V to 13.3V at IZT = 5.0mA. |
