LBZT52B4V7T1G 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, indicated by the polarity band on the SOD-123 package (Style 1: pin 1 = cathode). |
| 2 | ANODE | passive | Anode terminal (Style 1: pin 2 = anode); the forward voltage is specified as 0.9 V max at IF = 10 mA. |
