Product details
Overview
VLRE31R1S1-GS08 from Vishay Semiconductors is a reverse gullwing surface-mount yellow LED based on AlInGaP-on-GaAs technology, delivering 112–285 mcd luminous intensity at 20 mA, with dominant wavelength 582–594 nm and forward voltage 2.1–2.3 V. It is designed for top-down emission through PCBs in automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLRE31R1S1-GS08 datasheet, VLRE31R1S1-GS08 pinout, VLRE31R1S1-GS08 application, or VLRE31R1S1-GS08 equivalent, key selection criteria include luminous intensity binning (Group R), ±60° viewing angle, AEC-Q101 qualification, JEDEC Level 2 preconditioning, and compatibility with IR reflow per J-STD-020C.
Technical Context
This device operates as a top-emitting SMD LED mounted inverted on the PCB, requiring reverse gullwing soldering orientation. Its optical output is defined by non-diffused lens geometry enabling efficient coupling to light pipes, with luminous intensity ratio IVmax/IVmin > 1.6 within a reel.
It uses AlInGaP-on-GaAs epitaxy for high-efficiency yellow emission, rated for continuous DC forward current up to 30 mA at ≤85 °C ambient, with thermal resistance RthJA = 400 K/W when mounted on ≥16 mm² copper pad.

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLRE31R2S2-XY-GS08 | Higher luminous intensity bin (140–285 mcd); dominant wavelength 585–591 nm (Group X/Y) | Better suited for higher-brightness indicator roles where tighter wavelength control is required | Select when design requires >140 mcd minimum intensity or tighter 585–591 nm yellow bin |
| OSRAM LYT776-R1S2 | Same luminous intensity range and package; different binning methodology and thermal resistance (RthJA = 420 K/W) | Compatible in footprint and drive but requires validation of intensity consistency across reels | Choose for multi-source procurement where OSRAM supply chain alignment is preferred |
Compared with VLRE31R1S1-GS08, VLRE31R2S2-XY-GS08 offers higher minimum intensity and narrower wavelength tolerance, while LYT776-R1S2 provides second-source availability with minor thermal performance trade-off-both require verification of intensity bin compliance for critical visibility applications.
