Product Overview
The XL-1606SURC is a XINGLIGHT high brightness red SMD LED supplied in a compact 1.7 x 0.6 x 1.1 mm package. The device uses a transparent/water clear colloid and is categorized as an LED component for surface-mount applications where red optical output and a small package outline are required.
At IF=20 mA and Ta=25°C, the LED is specified for 90 to 210 mcd luminous intensity, 615 to 630 nm dominant wavelength, 625 nm typical peak wavelength, 20 nm typical half-wave width, and 120° typical viewing angle. Electrical ratings include 1.9 to 2.3 V forward voltage at IF=20 mA, 20 mA maximum continuous forward current, 80 mA peak forward current under the stated pulse condition, and 5 µA maximum reverse current at VR=5 V.
Assembly data includes MSL 3 moisture sensitivity, 168 hours floor life after opening at <=30°C and <40% RH, and a 60 ±15°C, 24-hour bake condition if storage limits are exceeded. Reflow soldering is limited to a maximum of two cycles, with a recommended maximum welding temperature of 240 ±15°C for 6 s.

Procurement Notes
When requesting a quote for XL-1606SURC, 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.
