LEDs are a key component of electronics and lighting, providing visibility and clear information to a user. With the emergence of low-cost, high-quality components, the demand for discrete LEDs has grown. The VEW1147LS-TR is a discrete LED indicator with a built-in transistor, making it an extremely versatile product that is suitable for a wide range of applications. This article will review the application field and working principle of this device.

Application Field

The VEW1147LS-TR is a discrete yellow LED that is ideally suited for use in automotive and industrial, as well as home, applications. It is designed to be used in circuit boards and panels, where visibility and clear indication are needed. The shape and size of the VEW1147LS-TR make it easy to install, even in tight spaces. Its built-in transistor acts as an interface between the LED and the power source, allowing for more reliable indication than a standard LED. This transistor is also capable of providing protection against over-voltage, surge, and short-circuit scenarios.

The VEW1147LS-TR has a wide input voltage range that can be used with a variety of different power sources. With its long life expectancy and low power consumption, the VEW1147LS-TR is an excellent choice for applications that require reliable, long-term performance. Thanks to its bright yellow light source and high visibility, the VEW1147LS-TR is also suited for applications where alerting users to a situation is important.

Working Principle

The VEW1147LS-TR is a discrete low-power LED indicator which works using a built-in transistor. The transistor acts as an interface between the LED and power source to protect against any overvoltage or surge. The circuit is closed when the power source is applied and the LED will be illuminated as long as the circuit is closed. The LED intensity is affected by the length of the closed circuit, so the longer the circuit is closed, the brighter the LED will be. The transistor prevents the LED from burning out if too much voltage is applied, as the transistor will act as a protective element in this scenario.

The LED indicator of the VEW1147LS-TR can be used in both AC and DC circuits. It can also be used in a variety of different configurations and orientations, allowing for maximum flexibility in circuit design. Additionally, the VEW1147LS-TR is designed with an ultra-low current consumption for more efficient operation.

Conclusion

The VEW1147LS-TR is a discrete LED indicator designed for use in automotive, industrial, and home applications. It has a built-in transistor interface to provide protection against overvoltage or surge. The LED indicator has a wide input voltage range and can be used in AC and DC circuits. The LED intensity is affected by the length of the closed circuit and its low current consumption makes it an efficient and reliable solution.
