ASMT-UWB1-ZAAF2

Overview

The ASMT-UWB1-ZAAF2 is a discrete white LED indicator from Broadcom Limited, housed in a PLCC-2 surface-mount package. It emits neutral white light at a color temperature of 4000K with a viewing angle of 120 degrees. The component operates with a forward current of 20mA and a typical forward voltage of 3.2V. It features a diffused lens for uniform light distribution and is designed for high reliability with silicone encapsulation.

Feature Summary

• Silicone encapsulation ensures high reliability and durability
• Compatible with standard reflow soldering processes
• Diffused lens provides uniform light emission

Applications

• LED indication
• Status indicators
• Backlighting

Procurement Notes

Verify the specific suffix ZAAF2 to confirm the neutral white color temperature and voltage characteristics. Ensure compatibility with PLCC-2 footprint requirements during PCB design. Check moisture sensitivity levels and storage conditions prior to assembly to maintain component integrity.

Selection Notes

Select this component when a neutral white light source is required for status indication or backlighting applications. The PLCC-2 package offers a compact solution for space-constrained designs. Consider the 120-degree viewing angle for visibility requirements and verify thermal management needs based on the specified power rating.

Part Context

This part belongs to the ASMT series of high-power LEDs manufactured by Broadcom Limited. The series is known for its high optical efficiency and reliability. The ASMT-UWB1-ZAAF2 specifically targets applications requiring neutral white illumination in a standard surface-mount form factor.

Replacement Considerations

Direct substitutes include other PLCC-2 white LEDs from Broadcom such as ASMT-UWB1-NX3F2 or ASMT-UWB1-ZAAC2, provided the color temperature and voltage specifications align with the design requirements. Verify pinout and dimensional compatibility before substitution.
