This document introduces the Semiconductor Group 1's semiconductor products released on November 12, 1998, including LS A679, LY A679, and LG A679. These products feature low current LEDs and are suitable for applications such as optical indicators, backlighting, optical coupling into light pipes and lenses. They are compatible with all SMT assembly and reflow soldering methods and are available taped on reel. The products come in different colors and luminous intensities to suit different application scenarios.
This document is a technical datasheet for the Siemens LC SIDELED series, specifically models LS A679, LY A679, and LG A679. These components are designed as low current LEDs suitable for use as optical indicators or for backlighting applications involving light pipes and lenses.
The datasheet provides detailed electrical characteristics, including forward voltage, reverse current, capacitance, and switching times for all three color variants (super-red, yellow, and green). It also lists maximum ratings such as operating temperature ranges from -55 to +100 °C and junction temperature limits. Additionally, the document includes graphical data on spectral emission, radiation characteristics, and thermal performance curves.
