Yongyu Photoelectric · LED Indication - Discrete · 0402
SZYY0402B 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, identified by the cathode mark on the package; reverse voltage must not exceed 5 V. |
| 2 | A | passive | Anode; forward current max 30 mA (60 mA peak, pulse width ≤0.1 ms, duty ≤1/10), typical Vf 3.2 V at IF=5 mA. |
