Product details
Overview
VLRK31Q1R2-GS08 from Vishay Semiconductors is a surface-mount red LED using AlInGaP-on-GaAs technology, optimized for indicator and backlighting applications with luminous intensity of 71–180 mcd at 20 mA, dominant wavelength 620–635 nm, and forward voltage 2.1–2.3 V. It features ±60° viewing angle, reverse gullwing SMD package, and AEC-Q101 qualification for automotive use.
For engineers reviewing the VLRK31Q1R2-GS08 datasheet, VLRK31Q1R2-GS08 pinout, VLRK31Q1R2-GS08 application, or VLRK31Q1R2-GS08 equivalent, key selection criteria include luminous intensity binning (Q-group), thermal resistance (400 K/W), JEDEC level 2 preconditioning, ESD withstand (2 kV), and compatibility with IR reflow per J-STD-020C.
Technical Context
This device operates as a top-down mounted red LED emitting through the PCB, housed in a white thermoplastic reverse gullwing package with clear epoxy lens and internal reflector. Its optical design delivers non-diffused output ideal for light-pipe coupling and flat backlighting.
It supports DC forward current up to 30 mA at ≤85 °C ambient, with surge capability of 1 A (10 μs), junction temperature limit of +125 °C, and storage/operating range of −40 to +100 °C. Junction capacitance is 15 pF at 0 V and 1 MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LST776-Q1R2 | OSRAM equivalent; identical luminous intensity bin (Q), same 620–635 nm wavelength, and matching reverse gullwing footprint | No AEC-Q101 qualification documented; intended for industrial/commercial rather than automotive use | Select when automotive qualification is not required and OSRAM supply chain preference applies |
| VLRK31R1S2-GS08 | Same package and technology but higher luminous intensity bin (R/S group: 112–285 mcd vs. Q's 71–180 mcd) | Higher brightness may require current derating or optical attenuation in space-constrained backlighting | Select when greater luminance is needed for outdoor-readable displays or longer light-pipe paths |
Compared with VLRK31Q1R2-GS08, LST776-Q1R2 offers identical optical and mechanical specs but lacks automotive qualification, while VLRK31R1S2-GS08 delivers higher brightness at the cost of tighter current control requirements in thermally constrained layouts.

FAQ
What is the luminous intensity range of the VLRK31Q1R2-GS08?
The VLRK31Q1R2-GS08 has a luminous intensity range of 71–180 mcd at 20 mA forward current, corresponding to the Q-group binning classification defined in the Vishay datasheet. This range ensures consistent brightness within each tape reel, with IVmax/IVmin > 1.6, and is measured using a 25 ms pulse at 25 °C ambient temperature.
Is the VLRK31Q1R2-GS08 suitable for automotive applications?
Yes, the VLRK31Q1R2-GS08 is AEC-Q101 qualified, confirming its suitability for automotive applications including dashboard backlighting and switch illumination. It meets rigorous requirements for temperature cycling, humidity resistance, and mechanical shock, and operates reliably from −40 to +100 °C ambient.
What is the maximum forward current rating for the VLRK31Q1R2-GS08?
The VLRK31Q1R2-GS08 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤85 °C. At higher ambient temperatures, derating is required per the datasheet's forward current vs. ambient temperature curve (Fig. 1), and surge current up to 1 A is allowed for pulses ≤10 μs.
Does the VLRK31Q1R2-GS08 require baking before reflow soldering?
No, the VLRK31Q1R2-GS08 is preconditioned to JEDEC level 2 and shipped in dry-packed anti-humidity bags with JESD22-A112 labeling, eliminating the need for baking prior to lead-free reflow. It supports peak reflow temperatures up to 260 °C per J-STD-020C without moisture-related defects.
What is the viewing angle specification for the VLRK31Q1R2-GS08?
The VLRK31Q1R2-GS08 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50% of peak value at 60° off-axis in both directions. This wide viewing angle supports uniform illumination across broad front-panel areas without secondary optics, as confirmed in Fig. 3 of the Vishay datasheet.
