TONYU · LED Indication - Discrete · 0603
DYWH-19-21SUGC from TONYU, 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, marked by the cathode mark on the bottom; reverse voltage max 5 V (IR test only, not designed for reverse operation). |
| 2 | A | passive | Anode (+) of the InGaN green LED; forward current max 25 mA (50 mA peak at 1 kHz, 1/10 duty), VF 1.95-2.75 V at IF=1mA, requires external series resistor. |
