BZT52-B33J from Nexperia, 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 | K | passive | Cathode of the Zener diode; the marking bar on the package indicates this terminal, and the 590 mW Ptot rating applies with a 1 cm² cathode mounting pad. |
| 2 | A | passive | Anode of the Zener diode; the datasheet gives no separate electrical limit for this pin. |
