Product Overview
XL-2520UBC-TR7 is a XINGLIGHT blue through-hole LED with a 2.1 x 2.3 x 2.6 mm body and Ø1.8 mm outline. The datasheet identifies blue light output with water colloid / transparent colloid construction, making it applicable where a narrow blue visual emission point is required.
Electrical and optical characteristics are specified at IF=20 mA and Ta=25°C. The LED has 900 to 1500 mcd luminous intensity, 460 to 470 nm dominant wavelength, 465 nm typical peak wavelength, 25 nm typical half wave width, 20° typical viewing angle, and 2.8 to 3.2 V forward voltage. Reverse current is limited to ≤5 µA at VR=5 V.
Absolute maximum ratings include 70 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current, 5 V reverse voltage, -20 to +85°C operation, and -40 to +85°C storage. Assembly guidance includes MSL 3 storage controls, 260°C maximum lead soldering for ≤6 s, recommended Pb-free reflow at 240°C ±5°C for 6 s, and a maximum of two reflow cycles.
