This document is about LSY T676 series of hyper bright LED, its features are that it can be used as optical indicator and for backlighting, optical coupling into light pipes and lenses. It has two independently controllable LED chips, which can achieve high signal efficiency by color change. It can change color from green to yellow and orange to super-red with appropriate control. The product is suitable for all SMT assembly and soldering methods and is available taped on reel (8 mm tape).
The Siemens LSY T676 is a Hyper Multi TOPLED® in a P‑LCC‑4 package, white housing, designed for use as an optical indicator, backlighting, and optical coupling into light pipes and lenses. Both LED chips are separately controllable, allowing color changes from green to yellow, orange, and super‑red with appropriate drive signals.
The device operates over a wide temperature range (‑55 °C to +100 °C) and provides typical electrical ratings such as a forward current of 30 mA, reverse voltage of 3 V, and power dissipation of 80 mW. Optical characteristics include a peak emission wavelength of 645 nm, a viewing angle of 120°, and a spectral bandwidth of 16 nm. The package dimensions are approximately 1.7 × 0.9 × 0.7 mm.
