DZL4744 from LGE, in a SOD-123FL. 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 | The cathode is the terminal marked by the laser band on the molded SOD-123FL case, per the polarity note in the mechanical data. |
| 2 | ANODE | passive | The anode is the terminal opposite the band-marked cathode; the datasheet gives no separate anode-specific limits. |
