LED SMD Blue 5730 - 2Pin

The Blue 5730 SMD LED

 is a high-brightness, medium-power diode (typically 0.5W) used in applications requiring more light than standard 2835 LEDs, such as in high-intensity light strips, automotive lighting, and backlighting. Its larger footprint (5.7mm x 3.0mm) allows for better heat dissipation and higher luminous efficiency. 

Key Specifications

According to technical datasheets from Sunrom and Hongfucheng Optoelectronics, standard 5730 blue LEDs feature these parameters:

• Forward Voltage (Vf): Typically 3.0V to 3.4V DC.
• Forward Current (If): Standard drive current is 150mA for 0.5W operation.
• Wavelength: Dominant blue light typically falls between 460nm and 470nm.
• Luminous Flux: Produces approximately 25 to 35 lumens (at 150mA), though some high-efficiency variants can reach up to 57 lumens.
• Dimensions: Standard 5.7mm x 3.0mm footprint.
• Viewing Angle: Wide distribution of 120°.
