Product Overview
The EVERLIGHT 15-21_GHC-R2S2_2T is a SMD brilliant yellow green LED using AlGaInP chip material with water clear resin. The datasheet identifies the package as SMD-B, with package dimensions provided in millimeters and tolerances of ±0.1 mm unless otherwise specified.
At IF=20 mA and Ta=25°C, the device is specified for 28.5 to 72.0 mcd luminous intensity, 575 nm typical peak wavelength, 567.5 to 575.5 nm dominant wavelength, 20 nm typical spectrum radiation bandwidth, and a 140° typical viewing angle. Forward voltage is specified from 1.75 to 2.35 V, with reverse current limited to 10 µA max at VR=5 V.
Assembly data includes 8 mm tape on a 7 inch diameter reel with 2000 pcs per reel. Pb-free reflow guidance lists a 260°C maximum peak, 10 seconds maximum above 255°C, 30 seconds maximum above 217°C, and no more than two reflow cycles. The device is not designed for reverse operation; the reverse-voltage condition applies to IR testing only.

Procurement Notes
When requesting a quote for 15-21_GHC-R2S2_2T, 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.
FAQ
What color does 15-21_GHC-R2S2_2T emit?
The datasheet identifies 15-21_GHC-R2S2_2T as a brilliant yellow green LED. Its optical data lists a 575 nm typical peak wavelength and a 567.5 to 575.5 nm dominant wavelength range at IF=20 mA and Ta=25°C.
What is the forward voltage range at 20 mA?
At IF=20 mA and Ta=25°C, the forward voltage is specified from 1.75 V minimum to 2.35 V maximum. The datasheet also lists a forward voltage tolerance of ±0.1 V in the electro-optical characteristics notes.
Can this LED be operated in reverse bias?
The datasheet states that the device is not designed for reverse operation. The 5 V reverse-voltage condition is tied to reverse-current testing only, where reverse current is specified as 10 µA maximum at VR=5 V and Ta=25°C.
What soldering limits apply to this SMD LED?
The soldering data lists 260°C for 10 seconds for reflow and 350°C for 3 seconds for hand soldering. The Pb-free profile also limits peak temperature to 260°C max and permits no more than two reflow cycles.
