156120YS75300

Overview

The 156120YS75300 is a single-color reverse-mount surface mount LED from the Würth Elektronik WL-SMRW series. It features a yellow AlInGaP chip emitting at a peak wavelength of 589 nm with a viewing angle of 140 degrees. The component utilizes a water-clear round flat lens within a 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm x 1.4 mm. Key electrical parameters include a forward voltage of 2 V and a maximum power dissipation of 35 mW to 80 mW, with an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Reverse-mount construction for low-profile surface mounting
• Water-clear round flat lens design
• High viewing angle of 140 degrees

Applications

• Indoor display indicators
• Optical equipment status signaling
• LCD backlighting applications

Procurement Notes

Verify the specific binning codes for luminous intensity and chromaticity coordinates against the manufacturer's datasheet prior to procurement. Confirm that the reverse-mount polarity orientation aligns with the target PCB footprint design. Ensure compliance with moisture sensitivity level requirements during storage and reflow soldering processes to maintain component reliability.

Selection Notes

Select this component when a low-profile yellow indicator is required for space-constrained designs. The reverse-mount configuration allows for minimal board thickness compared to standard SMD LEDs. Consider the 140-degree viewing angle for wide-area visibility needs. Evaluate thermal management capabilities given the 35 mW to 80 mW power dissipation rating for continuous operation scenarios.

Part Context

This part belongs to the WL-SMRW series of monochromatic SMD LEDs manufactured by Würth Elektronik. The series offers various colors in the 1206 footprint, providing consistent mechanical dimensions across the product line. These components are designed for automated assembly processes, supporting both tape-and-reel and cut-tape packaging formats for efficient manufacturing integration.

Replacement Considerations

Direct substitutes within the same series include other color variants such as 156120GS75300 or 156120RS75300 if color differentiation is required. Cross-manufacturer replacements must match the 1206 reverse-mount form factor and verify compatible forward voltage characteristics.
