LBZT52C33T1G from LRC, 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 terminal of the Zener diode, identified on the package by the polarity band per the datasheet's SOD-123 Style 1 pin assignment. |
| 2 | ANODE | passive | Anode terminal of the Zener diode, per the datasheet's SOD-123 Style 1 pin assignment and equivalent circuit (Cathode/Anode on pins 1/2). |
