Normally, Zener diodes are used as a countermeasure to static electricity in LEDs. However, in matrix circuits this can cause current to flow to other LEDs, resulting in unwanted light emission. In contrast, the MSL0402RGBU employs a high ESD resistance element that eliminates the need for a Zener protection diode, ensuring superior display performance in matrix circuits. The six-pin device can output up to 400mcd in red, up to 550mcd in green and up to 180mcd in blue.
The MSL0402RGBU uses a gold plated substrate that prevents sulfuration even when silicon resin packages are used. This minimizes brightness degradations and contributes to greater long-term application reliability.
