What are the key electrical specs?

It operates at a forward current of 25mA, with a forward voltage range of 1.8V to 2.4V and a luminous intensity of 40-48 mcd at 5mA.

What should be considered during assembly?

The device is moisture-sensitive. It must be handled according to the datasheet's baking instructions if the package is opened, and it requires a controlled reflow soldering process.

How should this LED be driven?

It must be driven with a current-limiting resistor to prevent excessive current flow, which can cause permanent damage to the LED.

What should sourcing teams check before buying SZYY0402Y?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of SZYY0402Y?

Use the SZYY0402Y datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SZYY0402Y pinout to locate pins, power rails, and interface signals before layout.
