LED Indication - Discrete

The C503C-WAS-CBADA151 is a discrete LED indicator manufactured by OSRAM that utilizes the OSRAM OSLON SX Hyper Red LED technology to deliver a light output performance ranging from 6cd to 12cd with a 2.5mA current. With a 2.5mA drive current, the C503C-WAS-CBADA151 can operate in temperatures ranging from -20°C to + 85°C making it suitable for extreme environments.

Application Field

The C503C-WAS-CBADA151 LED indicator is widely used in industrial, automotive, electrical and commercial applications in devices such as panel indicators, indicators displays, and alert systems. Its small size and high light output makes it suitable for a variety of applications, such as electroluminescent backlighting displays, circuitry boards, automotive warning labels, and even night safety lights.

Working Principle

The C503C-WAS-CBADA151 LED indicator was designed for the purpose of illuminating objects and providing an eye-catching response when the LED is lit. It operates in a two-stage operation where the LED is activated first and then the current is increased to reach the peak intensity of the LED. The LED indicator consists of one or more operating elements, including a light source and control element, connected to a microcontroller. When the control element receives an instruction, it causes the light source to become energized and emit light at the predetermined intensity.

The C503C-WAS-CBADA151 LED indicator also includes a current-controlled circuit. This circuit monitors the amount of current flowing through the LED and will adjust it to ensure that the light intensity remains steady and consistent. The maximum allowed current is 2.5 mA, and can range from 0.2 – 4mA depending on the application and ambient temperature. The current-controlled circuit is designed to protect the LED from being overloaded, as well as to control the colour of the emitted light.

In addition to the current-controlled circuit, the C503C-WAS-CBADA151 LED indicator also includes a built-in thermal protection circuit. This circuit is designed to sense when the LED is operating at an excessive temperature and will shut down the LED to prevent it from being damaged. This feature enables the LED to be used in extreme environments, such as in areas with high humidity or in applications where sudden extreme temperature drops may occur.
