The document describes the features and characteristics of the LB 3333, LT 3333 Hyper 3 mm (T1) LED, micro Diffused Hyper-Bright LED, including its package, optical parameters, and applications.
The OSRAM LB 3333 and LT 3333 are 3 mm (T1) micro‑diffused LEDs available in blue (470 nm) and true‑green (528 nm) with a narrow 30° viewing angle. The datasheet provides optical efficiency (2 lm/W blue, 8 lm/W green), forward current rating of 20 mA, and typical forward voltage values (3.4 V blue, 3.0 V green). It also lists maximum ratings such as reverse voltage (39 V) and power consumption (80 mW).
Additional sections describe ordering information, wavelength and brightness group classifications, relative spectral emission curves, and handling instructions. Revision history and safety notes clarify that the data are statistical and that the LEDs may be used in life‑support devices only with explicit approval. This manual is written in German.
