ASMT-YTD2-0BB02

Overview

The ASMT-YTD2-0BB02 is a high-brightness tricolor surface-mount LED from Broadcom Limited, housed in a PLCC-6 package. It integrates red, green, and blue emitters within a single white-diffused lens to produce full-color output. The component features a square lens shape with a clear appearance and supports standard SMD/SMT installation. Key electrical parameters include forward voltages of 2.1 V for red and 3.2 V for green and blue channels, with a typical forward current of 20 mA per channel. Optical performance specifies peak wavelengths at 622 nm (red), 530 nm (green), and 470 nm (blue). The device offers a wide viewing angle of 120 degrees and operates reliably within a temperature range of -40°C to +110°C.

Feature Summary

• Integrates three distinct color emitters into a unified surface-mount package for comprehensive color mixing capabilities.
• Utilizes a diffused white lens design to ensure uniform light distribution and consistent visual appearance across the viewing angle.
• Constructed with a black substrate to enhance contrast and reduce internal light reflection, improving overall luminous efficiency.

Applications

• Indicators requiring multi-state status signaling through color variation
• Backlighting systems for user interface panels and control keys
• Decorative lighting elements in consumer electronics enclosures

Procurement Notes

Verify that the specific ordering suffix matches the required optical and electrical characteristics, as variations exist within the ASMT series. Confirm moisture sensitivity level handling requirements during storage and reflow soldering processes. Ensure compatibility with standard lead-free assembly profiles specified by the manufacturer. Cross-reference the datasheet for any recent product change notices affecting pinout or material composition before finalizing procurement orders.

Selection Notes

Choose this component when space constraints necessitate a compact PLCC-6 form factor while requiring independent control over multiple colors. Evaluate thermal management needs given the operating temperature limits and power dissipation ratings. Consider the diffusion type if uniformity is critical compared to clear lens alternatives. Verify that the forward voltage drops align with the driving circuit's available headroom and current limiting strategies for each individual color channel.

Part Context

This part belongs to the ASMT series of surface-mount LEDs manufactured by Broadcom Limited. The series is designed for applications demanding reliable optoelectronic performance in compact footprints. The YTD2 variant specifically addresses the need for tricolor functionality within a standardized PLCC-6 housing, allowing designers to replace discrete single-color components with a single integrated solution for complex visual feedback systems.

Replacement Considerations

Direct substitutes include ASMT-YTB2-0BB02 and ASMT-YTB8-0BA02, which share similar tricolor PLCC-6 configurations. Verify mechanical dimensions and pin assignments to ensure board compatibility. Check spectral data and brightness levels to confirm functional equivalence in the target application environment.
