SZYY0402W

Yongyu Photoelectric · LED Indication - Discrete · 0402

SZYY0402W from Yongyu Photoelectric, in a 0402. 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 terminal of the white LED, identified by the cathode mark on the package; reverse voltage must not exceed VR 5 V.
2 A passive Anode terminal of the white LED; drive through a current-limiting resistor with IF max 20 mA (100 mA peak at 1/10 duty, 0.1 ms) and VF typ 2.8 V (2.4 to 3.0 V).
