Product Overview
XL-HD3535UYC-A4 is a XINGLIGHT yellow high-power LED built in a 3535 SMD LED package. The package outline is 3.5 x 3.5 x 2.2 mm with a transparent colloid lens construction and a stated dimensional tolerance of ±0.25 mm unless otherwise noted.
At IF=350 mA and Ta=25°C, the device is specified for 27-45 lm luminous flux, 585-595 nm dominant wavelength, 590 nm typical peak wavelength, 1.8-2.4 V forward voltage, and 120° typical half-light viewing angle. Absolute maximum ratings include 700 mA forward current, 1000 mA peak forward current for pulses up to 0.1 ms at duty ≤1/10, 3000 mW power dissipation, 2000 V electrostatic discharge, and 125°C maximum junction temperature.
Assembly and handling data include MSL 3 classification, Pb-free reflow recommendation of 240±5°C for 6 s, two reflow cycles maximum, and manual repair soldering below 300°C for less than 3 s per terminal. Storage guidance specifies unopened storage within 1 year at ≤30°C and ≤60% RH, and soldering within 168 hours after opening at ≤30°C and ≤40% RH.

Procurement Notes
When requesting a quote for XL-HD3535UYC-A4, 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.
