BZX84W-C5V1X from Nexperia, in a SOT-323-3. 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; the datasheet gives no pin-specific electrical limit, so the series limiting values in Table 5 apply. |
| 2 | n.c. | unconnected | Not connected internally; the datasheet specifies no function for this pin. |
| 3 | K | passive | Cathode of the Zener diode; the series limiting values in Table 5 apply, including forward current IF of 200 mA maximum. |
