HSMS-C170

LED Indication - Discrete Overview

The HSMS-C170 is a single-color surface-mount LED manufactured by Broadcom Limited, utilizing AlInGaP technology to emit red light. It operates within the 0805 (2012 metric) package format, measuring 2 mm in length, 1.6 mm in width, and 0.8 mm in height. The component features a diffused lens with a rectangular shape and colorless appearance, providing a viewing angle of 170 degrees. Key electrical parameters include a peak wavelength of 626 nm, a forward voltage of 2.1 V at a test current of 20 mA, and an optical intensity of 10 mcd. The device has a power rating of 52 mW and functions reliably across a temperature range of -40 C to +85 C.

LED Indication - Discrete Feature Summary

• Emits red light via AlInGaP semiconductor material
• Features a diffused rectangular lens for wide visibility
• Designed for standard surface-mount assembly processes

LED Indication - Discrete Applications

• General indicator lighting on electronic circuit boards
• Status indication in consumer electronics devices
• Visual signaling in industrial control panels

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version when sourcing, as optical characteristics may vary slightly between production batches. Confirm moisture sensitivity handling requirements prior to soldering, as the component is sensitive to humidity. Ensure that the supplier provides traceable documentation matching the Broadcom Limited manufacturer part number to guarantee authenticity and compliance with specified RoHS standards.

LED Indication - Discrete Selection Notes

Choose this component when a low-profile red indicator is required for space-constrained designs. The 0805 footprint offers a balance between visibility and board density. Consider the 170-degree viewing angle for applications requiring broad line-of-sight visibility. Evaluate the 2.1 V forward voltage drop against the system's available drive voltage to ensure adequate current regulation without excessive heat dissipation.

LED Indication - Discrete Part Context

This part belongs to Broadcom’s Chip LED series, which focuses on compact, high-reliability surface-mount indicators. The HSMS-C170 specifically addresses the need for red illumination in standard SMD layouts. It complements other colors in the same package family, allowing designers to maintain consistent mechanical footprints while varying optical output for multi-status applications.

LED Indication - Discrete Replacement Considerations

Direct substitutes include HSMC-C170 for clear lens variants or HSME-C170 for green emission in the same package. Cross-reference pinout compatibility and thermal resistance when replacing with components from other manufacturers to ensure identical mounting and performance characteristics.
