LEDs are well known for their wide range of usages, from normal sign and indicator lights to modernly sophisticated applications in a variety of fields. One of the most popular members of the LED family is the A1643B/SUR/S530-A3. This device has many unique applications and features, as well as an impressive working principle.

The A1643B/SUR/S530-A3 series consists of surface mount light emitting diodes (SMDs). These components are meant to be used as indicators, arrays, light bars, and bar graphs on circuit boards. They include a transparent diffused lens, which helps to disperse the emitted light evenly. This is a very important feature for applications that require uniform illumination across the entire LED. Additionally, each LED includes two mounting legs that can be easily soldered onto the desired surface of the circuit board.

The most popular application of the A1643B/SUR/S530-A3 is as an indicator on a circuit board. They are designed to draw minimal power, making them a perfect choice for low-power projects. Additionally, they are designed with a maximum forward voltage of 2.5V, giving them an excellent rating in terms of energy efficiency. In terms of brightness, they have a peak forward current of 30mA and a maximum luminous intensity of 40 mcd, making them a great choice for applications that require bright and efficient illumination.

Regarding their working principle, the A1643B/SUR/S530-A3 follows the standard two-lead LED design. At one of the leads, electricity flows from the battery or power supply and passes through the LED, which causes it to light up. The other lead acts as a common terminal and allows the current to complete its flow. When the voltage is applied to the leads, the electrons are forced to leave the negative end and are then drawn to the positive end, releasing energy in the form of photons and causing the LED to emit visible light.

Overall, the A1643B/SUR/S530-A3 series is a great choice for circuit board applications that require indicator lights, arrays, light bars, and bar graphs. With an impressive working principle, a low power draw, and a maximum luminous intensity of 40 mcd, these LEDs can be used in a variety of applications, including automotive, communications, and industrial systems.
