Product Overview
The 17-21UYC-S530-A2_TR8 is an EVERLIGHT SMD blue indicator LED built in the 17-21 SMD B package. The datasheet identifies the emitted color as blue, the chip material as InGaN, and the resin color as water clear. Package dimensions are provided in millimeters, with tolerances of ±0.1 mm unless otherwise noted.
At Ta=25°C, absolute maximum ratings include 20 mA forward current, 40 mA peak forward current under duty 1/10 at 1 kHz, 75 mW power dissipation, and 5 V reverse voltage for the reverse-current test condition. The device is not designed for reverse operation. Operating temperature is specified from -40 to +85°C, with storage from -40 to +90°C.
Optical and electrical characteristics at IF=20 mA and Ta=25°C include 45.0 to 112.0 mcd luminous intensity, 140 degree typical viewing angle, 468 nm typical peak wavelength, and 2.7 to 3.7 V forward voltage. Assembly data includes 8 mm tape on a 7 inch reel, 3000 pieces per reel, reflow up to 260°C for 10 seconds, and a limit of no more than two reflow soldering cycles.

Procurement Notes
When requesting a quote for 17-21UYC-S530-A2_TR8, 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 17-21UYC-S530-A2_TR8 emit?
The datasheet identifies 17-21UYC-S530-A2_TR8 as a blue SMD indicator LED. The device selection guide lists blue emitted color, InGaN chip material, and water clear resin.
What are the main optical ratings at 20 mA?
At IF=20 mA and Ta=25°C, luminous intensity is specified from 45.0 to 112.0 mcd, viewing angle is 140 degrees typical, peak wavelength is 468 nm typical, and dominant wavelength is 464.5 to 476.5 nm.
What soldering limits apply to this LED?
The datasheet specifies reflow soldering at 260°C for 10 seconds and hand soldering at 350°C for 3 seconds. It also states that reflow soldering should not be performed more than two times.
