BZX884-B4V3

Nexperia · Zener Diodes · SOD-882

BZX884-B4V3 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, and the total power dissipation is limited to Ptot ≤ 250 mW at Tamb ≤ 25 °C.
2 A passive Anode of the Zener diode; the datasheet gives no pin-specific electrical limits beyond the device ratings (IF max 200 mA, Tj max 150 °C).
