**Nexperia** · Zener Diodes · SOD-882

BZX884-B2V4 from Nexperia, in a SOD-882. 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 | K | passive | Cathode of the Zener diode; the marking bar on the package indicates the cathode. |
| 2 | A | passive | Anode of the Zener diode; the datasheet gives no separate electrical limits for this pin beyond the device ratings (Ptot ≤ 250 mW, IF 200 mA, Tj 150 °C). |
