BZT55B4V3 from AnBon, in a SOD-123. 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 BZT55B Zener diode, identified on the package by the cathode band (page 4 pinning: Pin1 cathode; page 1: polarity indicated by cathode band). |
| 2 | Anode | passive | Anode of the BZT55B Zener diode, the terminal opposite the cathode band (page 4 pinning: Pin2 anode). |
