The 65-21SYGC/S530-E3/TR8 is a surface-mount (SMD) bi-color LED manufactured by Everlight Electronics Co., Ltd. It combines Super Yellow and Green LED chips within a single package. This allows the device to emit either color independently or both simultaneously to create a mixed color output. Everlight is a prominent manufacturer of optoelectronic components, including LEDs, displays, and optical sensors.

The '65-21' likely identifies the package type or dimensions, and the 'SYGC' indicates 'Super Yellow Green Common Cathode'. The '/S530-E3' specifies the intensity and wavelength characteristics, along with any specific binning or testing criteria. The '/TR8' likely indicates the packaging type, potentially tape and reel for automated assembly.

Applications:

• Status indicators for electronic devices
• Backlighting for LCD displays
• Automotive lighting
• Industrial control panels
• Medical equipment

Features:

• Surface-mount package
• Super Yellow and Green color emission
• Common cathode configuration
• High luminous intensity
• Low power consumption
• Wide viewing angle
• RoHS compliant

Benefits:

• Compact size for space-constrained applications
• Versatile color options
• Simplified circuit design with common cathode
• Easy to integrate into automated assembly processes
• Long lifespan for reliable operation

Key technical specifications include forward voltage (typically around 2.0V for Yellow and 2.2V for Green), luminous intensity (ranging from a few mcd to several hundred mcd depending on the drive current and specific binning), and viewing angle (typically around 120 degrees). The specific wavelengths for the Super Yellow and Green emissions will be detailed in the datasheet, allowing designers to accurately predict the resulting color mix.

The common cathode configuration simplifies the driving circuitry by allowing a single ground connection for both LEDs. The device's low power consumption and high luminous intensity make it ideal for battery-powered applications. Engineers should consult the official Everlight datasheet for the 65-21SYGC/S530-E3/TR8 for detailed specifications, recommended operating conditions, and soldering guidelines. The 'TR8' suffix is usually associated with a specific reel size and number of components per reel.
