DZL4734 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 | K | passive | Cathode, marked by the laser band on the SOD-123FL body; DZL4734 is the 4.3 V nominal (4.08 to 4.52 V at IZT = 58 mA) zener. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; power dissipation is rated 1.0 W and junction temperature 150 °C. |
