DL4744A from LGE, in a MELF. 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 cathode band on the MELF glass body; the zener diode is reverse-biased here for regulation (DL4744A: 15 V nominal at 17 mA test current, 1.0 W max dissipation at Tamb ≤ 50 °C). |
| 2 | A | passive | Anode, the terminal opposite the cathode band; forward voltage is max 1.2 V at IF=200 mA. |
