APTD1608SECK

Kingbright · LED Indication - Discrete · 0603

APTD1608SECK from Kingbright, in a 0603. 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 of the Hyper Red AlGaInP LED, marked by the polarity mark on the package underside, with reverse current of 10 µA max at VR = 5 V.
2 A passive Anode of the Hyper Red AlGaInP LED, with DC forward current up to 30 mA (IF max), typical VF 2.2 V at 20 mA, and reverse voltage limited to 5 V.

CAD (KiCad official)

  • Symbol: APTD1608SECK
  • Footprint: LED_SMD:LED_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: aptd1608seck-etched.step / aptd1608seck-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aptd1608seck.step / aptd1608seck.glb are the bare package body.
