ROHM Semicon · LED Indication - Discrete · 0603
SMLEN3WBC8W1 from ROHM Semicon, 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 electrode, marked by the cathode index on the left of the top view; forward current IF max 10mA (peak 50mA at duty 1/10, 1kHz) flows into the anode and out of this pin, and reverse voltage must not exceed 5V. |
| 2 | A | passive | Anode electrode on the opposite end from the cathode index; forward voltage VF is 2.5 to 3.3V (typ 2.9V) at IF=5mA, and constant-current drive is recommended. |
