Product Overview
XL-3535UV2SB12P2 is a XINGLIGHT dual-wavelength UV germicidal LED supplied in a 3535 SMD package with 3.5 x 3.5 x 1.45 mm outline dimensions. The package appearance is purple with a plane lens, and the moisture sensitivity level is MSL 3.
The LED provides separate UVC and UVA operating characteristics. At IF=40 mA and Ta=25°C, the UVC channel is specified at 5.0 V minimum, 5.5 V typical, and 6.4 V maximum forward voltage, with 5 mW minimum to 8 mW maximum radiation flux and a 260-280 nm peak wavelength range. The UVA channel is specified at 3.0-3.4 V forward voltage, 40 mW typical radiation flux, and 395 nm typical peak wavelength.
Absolute maximum ratings include 200 mW maximum power dissipation for each channel, 40 mA maximum UVC forward current, 60 mA maximum UVA forward current, and 100 mA maximum peak forward current under pulsed conditions. Assembly limits include 260°C maximum soldering temperature for up to 6 seconds, two Pb-free reflow cycles maximum, and recommended reflow at 240 ±5°C for 6 seconds.

Procurement Notes
When requesting a quote for XL-3535UV2SB12P2, 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.
