WP56BHD Datasheet/PDFLED Indication - Discrete
LED indicators have become the go-to solution for practically any application that requires visibility, be it automotive, industrial, consumer, or even medical. And within the wide range of LED types that exist, there’s one known as the WP56BHD which has become a popular choice within these areas. Let’s look at its application field and working principle to better understand why.
Application Field
The WP56BHD’s diverse application field means that it can be used within various industries due to its unique design. In industrial applications, it can be used for machine control indicators, hour meters, or for panel indicator lights. Its non-polarity design also makes it a great choice for automotive and consumer applications, such as in dashboard or dashboard warning lights.
The WP56BHD’s physical characteristics also make it ideal for medical applications like thermometers or hear monitors. It has a low-time intensity and long time visibility, making it perfect for medical diagnostic devices that require accuracy and visibility. Additionally, it has a low power consumption, so it’s also used in battery-powered devices.
Working Principle
The WP56BHD has a unique design that makes it intrinsically ESD and EMI-resistant. It consists of two lamps with different luminous intensity characteristics inside a single shell. The first lamp is a transistor-like LED diode whose luminosity rely on the negative bias of the external power. The second lamp is formed from the combination of two parallel transistors whose luminosity is regulated by the external power.
The design of the WP56BHD allows it to switch on and off quickly due to the rapid buildup of charge in the diodes. These fast switching times make it an efficient choice for applications with frequent power cycling. The WP56BHD also features an integrated thermal protection circuit that prevents the lamp from getting damaged during power cycling.
Another benefit of the WP56BHD is its wide operating temperature range. This renders it suitable for use within a wide range of environments, including -55°C to +125°C. Additionally, the WP56BHD has a long life expectancy of up to 50,000 hours.
Conclusion
The WP56BHD gives its users a unique combination of characteristics that make it a great choice for various applications. Its two lamps, swift on/off switch, and wide operating temperature range, coupled with its ESD and EMI protection, give it an edge over other types of LED indicators, making it a popular choice for industrial, automotive, medical, and consumer applications.
