This TOPLED series of LEDs from OSRAM Opto Semiconductors feature a black surface. The black surface makes them ideal for use in displays and signalling applications, with the black surface offering a high on-off contrast. As with the standard TOPLED series, they are compact and highly reliable LEDs. Available in a range of different colour options, including yellow, they come in a standard PLCC-2 package.
Note
Amber LEDs – Originally designed for use in automotive brake-light applications, OSRAM amber LEDs can appear red due to a high dominant wavelength value. Refer to a dominant wavelength colour chart to find your chosen LED colour.
