Product Overview
XL-3535UV1SB12P1 is a XINGLIGHT UVC purple sterilization LED supplied in a 3535 SMD package with outline dimensions of 3.5 x 3.5 x 1.45 mm. The package uses a plane lens colloid and specifies purple luminous color. Moisture sensitivity is MSL 3, with unopened storage limited to <=30°C, <60% RH within 1 year and opened storage limited to <=30°C, <40% RH with soldering within 168 hours.
At Ta=25°C, the LED is specified for 260-280 nm peak wavelength, 3-5 mW radiation flux, 120 degree typical half light angle, and 15 nm typical half wave width. Electrical limits include 40 mA forward current, 100 mA peak forward current under pulse conditions, 200 mW power dissipation, 3000 V ESD rating, and max 5 uA reverse current at VR=5 V.
Assembly guidance includes 260°C lead soldering for <=6 s, Pb-free reflow at 240±5°C for 6 s, maximum two reflow cycles, and manual repair soldering below 300°C for less than 3 s per terminal.

Procurement Notes
When requesting a quote for XL-3535UV1SB12P1, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
