Product Overview
The XL-TD3838UVA1-A4 is a XINGLIGHT LED described as a 365 nm UV sterilization LED. It is supplied in a 3838 package with outline dimensions of 3.9 x 3.9 x 3.1 mm and an outline dimension tolerance of ±0.25 mm unless otherwise noted. The optical construction is listed with transparent colloid and purple luminous color.
Electrical and optical ratings include a 360-370 nm main wavelength at Ta=25°C. At IF=500 mA and Ta=25°C, radiant flux is specified from 750-1200 mW, with bins P3-3 at 750-900 mW and P3-4 at 900-1200 mW. Forward voltage is 3.2-3.8 V at IF=500 mA, with R22-3 and R25-3 voltage bins covering 3.2-3.5 V and 3.5-3.8 V.
Assembly handling is defined by MSL 3 storage guidance, 2 maximum reflow cycles, and a recommended maximum reflow temperature of 240°C ±5°C for 6 s. The device is suited to UV sterilization LED modules where 360-370 nm output, package size, and soldering controls are design inputs.
