LBZT52B2V4T1G 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, marked by the polarity band on the package, per the SOD-123 Style 1 pin assignment (PIN 1 = CATHODE). |
| 2 | ANODE | passive | Anode, per the SOD-123 Style 1 pin assignment (PIN 2 = ANODE), with the equivalent circuit showing pin 1 as cathode and pin 2 as anode. |
