Product Overview
XL-HD3535SURC-A2 is a XINGLIGHT red high power LED built in a 3.5 x 3.5 x 2.2 mm SMD package. The optical construction is listed as red luminous color with transparent colloid, and the half-intensity viewing angle is typically 130° at Ta=25°C.
At IF=350 mA and Ta=25°C, the LED is specified for 40 to 60 lm luminous flux, 615 to 625 nm dominant wavelength, 625 nm typical peak wavelength, and 1.8 to 2.4 V forward voltage. Absolute maximum ratings include 1000 mW power dissipation, 350 mA forward current, 700 mA peak forward current under pulsed conditions, 3000 V ESD rating, and a maximum junction temperature of 145°C.
Assembly and storage requirements include MSL 3 moisture sensitivity, a 260°C lead soldering limit for no more than 6 s, maximum two Pb-free reflow cycles, and recommended reflow temperature of 240 ±5°C for 6 s. Opened packages should be soldered within 168 hours at <=30°C and <40% RH.

Procurement Notes
When requesting a quote for XL-HD3535SURC-A2, 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.
