DY-202SDRD

TONYU · LED Indication - Discrete · LED_D3.0mm

DY-202SDRD from TONYU, in a LED_D3.0mm. 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 Cathode passive LED cathode; reverse voltage VR max 5 V, reverse current IR max 10 μA at VR=5 V.
2 Anode passive LED anode (marked ANODE on the longer lead); forward current IF max 25 mA, VF 1.7-2.4 V at IF=20 mA, 2.54 mm lead spacing.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin The kinked tooling scrape easily the pin of LED, where the LED bracket is rusting easily, especial expose it in moist air. To decrease the LED bracket rust, advise using plated tin LED bracket. 8
