DL4744A

LGE · Zener Diodes · MELF

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.
