AA3528SECKT/J309

Overview

The AA3528SECKT/J309 is a single-color surface-mount LED from the HELI-R series, manufactured by Kingbright. It emits red light with a peak wavelength of 640 nm and a dominant wavelength of 625 nm. The component features a water clear lens with a round flat shape and a viewing angle of 120 degrees. Electrical characteristics include a forward voltage of 2.2 V at a test current of 20 mA, resulting in an optical intensity of 450 mcd. Physical dimensions are 3.20 mm in length, 2.80 mm in width, and a maximum height of 2.15 mm. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes a water clear lens to enhance light transmission efficiency for indicator applications.
• Provides a wide 120-degree viewing angle for broad visibility in panel mounting scenarios.
• Constructed with a standard 2-SMD package suitable for automated surface mount assembly processes.

Applications

• Panel indicators for electronic equipment
• Status indication on control boards
• Instrumentation display modules

Procurement Notes

Verify that the specific suffix J309 matches the required reel configuration and moisture sensitivity level (MSL 3) for your manufacturing process. Confirm RoHS3 compliance status if operating in regulated regions. Ensure the ordering part number aligns exactly with the datasheet specifications to avoid discrepancies in lens transparency or wavelength tolerance during procurement.

Selection Notes

Select this component when a standard red SMD LED with moderate brightness is required for general purpose indication. Consider the 120-degree viewing angle for visibility requirements. Evaluate the 2.2 V forward voltage drop against your circuit design constraints. Compare physical height limits against available PCB space before finalizing the selection.

Part Context

This device belongs to the HELI-R series of single-color LEDs produced by Kingbright. The series offers various color options in similar surface-mount packages. The AA3528SECKT/J309 specifically denotes the red variant with defined electrical and optical parameters. It serves as a discrete indicator component within broader lighting and signaling product lines.

Replacement Considerations

Direct substitutes include AA3528SYCKT/J309 for yellow variants or AA3528SURCK for red hyperbright versions. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with KA-3528SECKT aliases for equivalent sourcing options.
