Product Overview
XL-2106SURC is a XINGLIGHT high-brightness red SMD LED supplied in a 2.1 x 0.55 x 1.01 mm surface-mount package. The device uses a water-clear colloid / transparent encapsulant and is specified as MSL 3 for moisture sensitivity handling.
At IF=20 mA and Ta=25°C, the LED provides 80 to 240 mcd luminous intensity, 615 to 630 nm dominant wavelength, 625 nm typical peak wavelength, 1.7 to 2.3 V forward voltage, 120° typical viewing angle, and 20 nm typical half wave width. The reverse current limit is <=5 µA at VR=5 V.
Absolute maximum ratings include 50 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current for pulse width <=0.1 ms and duty <=1/10, 5 V reverse voltage, and 2000 V ESD antistatic ability at Ta=25°C. Assembly guidance includes up to two reflow cycles, 240±5°C for 6 s recommended maximum welding temperature, and defined storage, baking, and cleaning conditions.

Procurement Notes
When requesting a quote for XL-2106SURC, 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.
