DY-IR204C

TONYU · Infrared LED Emitters · LED_D3.0mm

DY-IR204C 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 K passive Cathode of the infrared emitting diode; reverse voltage max 5V, reverse current max 10μA at VR=5V.
2 A passive Anode of the GaAlAs 940nm infrared emitting diode (longer lead); forward current max 100mA continuous, 1.0A peak (pulse width ≤100μs, duty ≤1%), VF typ 1.2V at IF=20mA.

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
