Product Overview
XL-3535UV2SB12P1 is a XINGLIGHT dual-wavelength UV sterilization LED built in a compact 3535 SMD package. The package outline is 3.5 x 3.5 x 1.45 mm with a purple, plane-lens construction and dimensional tolerance of ±0.25 mm unless otherwise noted.
The device includes a UVC wavelength chip and is specified for both UVC and UVA operation. At IF=40 mA and Ta=25°C, the UVC channel has a forward-voltage range of 5.0 to 6.4 V, 3 to 5 mW radiation flux, and 260 to 280 nm peak wavelength. The UVA channel is specified at 3.0 to 3.4 V, 40 mW typical radiation flux, and 395 nm typical peak wavelength.
Assembly guidance includes MSL 3 handling, reflow soldering no more than two times, a recommended maximum reflow temperature of 240±5°C for 6 seconds, and floor life of 168 hours after opening under specified storage conditions. These parameters support UV sterilization designs requiring paired UVC and UVA emission in a surface-mount LED package.
