BZX84J-B9V1 from Nexperia, in a SOD-323F. 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 | cathode | passive | Cathode of the Zener diode, identified by the marking bar on the package; the datasheet gives a forward current limit of 250 mA (IF, Table 5) for the device. |
| 2 | anode | passive | Anode of the Zener diode; the device has a total power dissipation limit of 550 mW at Tamb ≤ 25 °C (Ptot, Table 5) and a junction temperature limit of 150 °C. |
