Product details
Overview
VLRE31R1S2-GS08 from Vishay Semiconductors is a surface-mount yellow LED using AlInGaP-on-GaAs technology, designed for top-down emission through PCB substrates. It delivers luminous intensity of 112–285 mcd at 20 mA, with dominant wavelength 582–594 nm, forward voltage 2.1–2.3 V, and ±60° viewing angle - optimized for automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLRE31R1S2-GS08 datasheet, VLRE31R1S2-GS08 pinout, VLRE31R1S2-GS08 application, or VLRE31R1S2-GS08 equivalent, key selection criteria include its reverse gullwing SMD package, AEC-Q101 qualification, JEDEC level 2 preconditioning, 2 kV ESD rating, and compatibility with IR reflow per J-STD-020C.
Technical Context
This device operates as a top-emitting, non-diffused yellow LED with a white thermoplastic reflector cavity filled with clear epoxy. Its AlInGaP-on-GaAs die structure enables high brightness and stable wavelength output in harsh environments.
Designed for reverse gullwing mounting, it emits light downward through the PCB substrate - requiring cutouts or transparent substrates. Thermal resistance junction-to-ambient is 400 K/W on >16 mm² pads, supporting operation from –40 °C to +100 °C ambient with 125 °C max junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 112–285 mcd at 20 mA - defines visible brightness range across binned reels; IVmax/IVmin > 1.6 ensures consistent intensity grouping |
| Dominant wavelength | 582–594 nm - places output in standard yellow band; supports color-coded indicators and backlight matching |
| Forward voltage | 2.1–2.3 V at 20 mA - enables low-power drive with standard 3.3 V or 5 V logic-level current limiting |
| Viewing angle | ±60° - provides wide dispersion suitable for uniform backlighting without secondary optics |
| ESD withstand | 2 kV HBM (JESD22-A114-B) - allows safe handling in standard assembly lines without special ESD controls |
| AEC-Q101 qualified | Validated for automotive use - meets stress testing requirements for under-hood and cabin electronics |
| Thermal resistance | 400 K/W - requires ≥16 mm² copper pad for thermal management at 30 mA max continuous current |
Pinout & Package
VLRE31R1S2-GS08 uses a 2-terminal reverse gullwing SMD package (JEDEC-compliant), with cathode and anode leads bent downward for soldering to PCB pads beneath the LED body. No internal pins - terminals are exposed metal leads embedded in white thermoplastic housing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source; polarity must be observed to avoid reverse breakdown (VR = 5 V max) |
| Cathode (K) | Negative LED terminal | Typically grounded; reverse bias must be limited to ≤5 V for short-term use only |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit LCD backlights without scattering loss |
| Luminous intensity binning | Guarantees IVmax/IVmin > 1.6 within each reel - eliminates manual sorting for consistent brightness |
| Low-profile SMD construction | Minimizes Z-height for space-constrained front-panel designs and thin display assemblies |
| IR reflow compatible | Withstands peak temperatures up to 260 °C per J-STD-020C - supports automated high-volume assembly |
| AEC-Q101 qualification | Validates reliability for automotive interior lighting, including dashboard switches and HVAC indicators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LYT776-R1S2 | OSRAM cross-reference; identical luminous intensity bin (R1), same dominant wavelength range and forward voltage | Same automotive and industrial indicator use cases; validated for identical reflow profiles and tape packaging | Select when sourcing from OSRAM-aligned supply chains or requiring dual-sourcing flexibility |
| VLRE31R2S2-XY-GS08 | Higher minimum luminous intensity (140 mcd vs. 112 mcd); tighter dominant wavelength bin (585–591 nm vs. 582–594 nm) | Better suited for applications requiring higher baseline brightness or stricter color consistency across units | Choose when brightness uniformity across production batches is critical, e.g., multi-LED status arrays |
Compared with VLRE31R1S2-GS08, LYT776-R1S2 offers identical photometric performance and mechanical fit, while VLRE31R2S2-XY-GS08 trades wider wavelength tolerance for higher minimum intensity - enabling design margin in low-light visibility-critical applications.

FAQ
What is the maximum continuous forward current for VLRE31R1S2-GS08?
The absolute maximum DC forward current for VLRE31R1S2-GS08 is 30 mA at ambient temperatures ≤ 85 °C. Operation above this value risks accelerated degradation and thermal runaway. Derating is required above 85 °C ambient, and the device must be mounted on a PCB pad > 16 mm² to maintain junction temperature ≤ 125 °C. VLRE31R1S2-GS08 is rated for 20 mA nominal operation per its optical specifications.
Is VLRE31R1S2-GS08 suitable for automotive applications?
Yes, VLRE31R1S2-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive interior electronics. It is explicitly recommended for dashboard backlighting and switch indicators. VLRE31R1S2-GS08 operates from –40 °C to +100 °C ambient and supports reflow soldering per J-STD-020C - fulfilling key automotive manufacturing requirements.
What does "GS08" mean in VLRE31R1S2-GS08?
"GS08" denotes the tape-and-reel packaging variant: reels contain 2000 units, use 180 mm diameter reels, and comply with EIA-481-D standards. The "GS" prefix indicates Vishay's standard dry-packaged, moisture-sensitive device format with JEDEC level 2 labeling; "08" specifies the reel size and quantity configuration. VLRE31R1S2-GS08 is not compatible with GS18 (8000-unit) reels.
Can VLRE31R1S2-GS08 be used in reverse-bias configurations?
Reverse voltage is limited to 5 V maximum, and the datasheet states reverse-direction driving is suitable only for short-term applications. VLRE31R1S2-GS08 is not designed for sustained reverse conduction or AC operation. Prolonged reverse bias may cause irreversible damage due to low reverse breakdown margin. Always operate VLRE31R1S2-GS08 in forward bias with appropriate current limiting.
How is luminous intensity binned for VLRE31R1S2-GS08?
VLRE31R1S2-GS08 is binned into luminous intensity groups (e.g., R1: 112–140 mcd) per the datasheet's LUMINOUS INTENSITY CLASSIFICATION table. Each reel contains only one brightness group - no mixing across bins - ensuring consistent output across a production lot. The ratio IVmax/IVmin > 1.6 guarantees predictable intensity spread, and VLRE31R1S2-GS08 ships exclusively in R1 or S1/S2 groups depending on order specification.
