DZL4747 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; DZL4747 has a nominal Zener voltage of 20 V (19.00-21.00 V) at IZT = 12.5 mA. |
| 2 | A | passive | Anode, the unbanded terminal of the glass passivated Zener diode; power dissipation is 1.0 W and junction temperature is 150 °C. |
