APT1608SYCK

Kingbright · LED Indication - Discrete · 0603

APT1608SYCK 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 LED, on the pad that the diode symbol's bar points to (the polarity mark is on the package-drawing bottom view); reverse current is at most 10 µA at VR = 5 V.
2 A passive Anode of the AlGaInP super bright yellow LED; the diode symbol on the package drawing points from pin 1 to pin 2, with a rated DC forward current of 30 mA, typical VF of 2.0 V (max 2.5 V) at 20 mA, and reverse voltage limit of 5 V.
