LEDs are a popular and versatile light source for providing visual indication in a number of different applications. Discrete LEDs, such as the CMDA5AA7D1S, are specifically designed for rugged, reliable use in high-vibration environments or where the highest of standards must be met. These small size discrete LEDs are designed for surface mount applications and provide a wide range of color choices and viewing angles.

Application Field

CMDA5AA7D1S diodes are very popular and widely used in many demanding applications including automotive safety systems, medical products, industrial applications, military/aerospace systems, and more. The high vibration-resistant design ensures reliability in hostile environments and the unit has a long life expectancy even with frequent cycles of power on and off.

In addition to the small size, the CMDA5AA7D1S offers many advantages, including a compact footprint and low power consumption, thanks to a fractional watt rating of just 0.3 watts. The LEDs are designed for use in applications where space is at a premium and the unit can easily be mounted in electronic devices without taking up valuable space. The low wattage also means it can be used in devices that require long battery life.

The CMDA5AA7D1S is also well suited for use in automotive or marine applications where its small size and versatile color options can be used to indicate various warnings or indications. Its wide viewing angle is also helpful in these applications, as well as in industrial settings where wide angle illumination is required.

Working Principle & Features

The CMDA5AA7D1S works by emitting light when electricity is passed through it. This is due to electron movement within the unit, which excites atoms within the LED. When these electrons return to their original energy level, they emit light in the form of a unique color. This is what makes LEDs so versatile, as they can be made in multiple colors.

The desired color is created by a combination of Gallium Arsenide Phosphide (GaAsP) crystals embedded in the diode. The varying sizes of the crystals determine the wavelength of the emitted light. Typically, there are three sizes of crystals used in the CMDA5AA7D1S – red, orange, and green.

The unit is also designed to be vibration resistant and will easily survive most conditions encountered in automotive and industrial applications. Additionally, the CMDA5AA7D1S has an operating temperature range of -40 to 135 degrees Celsius and an integrated heat sink for improved thermal performance. This helps ensure the unit’s performance over a wide range of temperatures, making it reliable and minimising the need for replacements.

Overall, the CMDA5AA7D1S is a reliable, robust, and versatile LED that can be used in many applications, both in automotive and industrial settings. Its small size, low power consumption, and wide viewing angle make it ideal for applications where space is at a premium, while the vibration-resistant design ensures reliability and a long life expectancy. For these reasons, it remains a popular and widely used LED for many applications.
