This document describes the features and characteristics of LB W5SM and LT W5SM Golden DRAGON® lead-free products. These products have high luminous flux and compact size, making them suitable for various applications such as LCD backlighting, indoor and automotive lighting.
The OSRAM LB W5SM and LT W5SM series are thin‑GaN LEDs offered in a white SMD package with a clear silicone resin. They provide point‑light sources with high luminous efficiency and low space requirements, suitable for TFT backlighting, automotive interior lighting, marker lights, RGB strobe and signal applications.
The document lists typical performance parameters such as luminous flux, dominant wavelength, viewing angle and optical efficiency, as well as maximum ratings, ordering codes, brightness‑group definitions and packaging notes. It also includes handling instructions like IR reflow soldering and ESD protection up to 2 kV. This manual is written in German.
| Dominant Wavelength (deep blue) | 455 nm |
|---|---|
| Viewing Angle | 120° (Lambertian) |
| ESD Withstand Voltage | 2 kV |
The devices are not designed for reverse operation; no reverse voltage rating is provided.
They are ESD‑safe up to 2 kV according to JESD22‑A114‑B.
IR reflow soldering is the recommended assembly method.
