Product details
Overview
VLRE31R1S1-GS18 from Vishay Semiconductors is a yellow surface-mount LED using AlInGaP-on-GaAs technology, designed for top-down emission through the PCB in reverse gullwing SMD package. It delivers luminous intensity of 112–285 mcd at 20 mA, dominant wavelength 582–594 nm, and forward voltage 2.1–2.3 V, targeting automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLRE31R1S1-GS18 datasheet, VLRE31R1S1-GS18 pinout, VLRE31R1S1-GS18 application, or VLRE31R1S1-GS18 equivalent, key selection criteria include luminous intensity binning (R1 group), ±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, reverse-mounted SMD LED with non-diffused lens optimized for light-pipe coupling and flat backlighting. Its AlInGaP-on-GaAs die structure enables high brightness in yellow spectrum while maintaining thermal stability up to +125°C junction temperature.
Designed for automated placement and lead-free reflow soldering, VLRE31R1S1-GS18 meets CECC 00802 and J-STD-020C process standards, supports 30 mA DC forward current, and exhibits 2 kV ESD withstand voltage per JESD22-A114-B - critical for industrial and automotive assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 112–285 mcd at 20 mA - defines brightness range within R1 bin for consistent visual output across production reels |
| Dominant wavelength | 582–594 nm - specifies yellow chromaticity suitable for automotive dashboard symbol illumination |
| Forward voltage | 2.1–2.3 V at 20 mA - determines driver voltage headroom and power dissipation in constant-current circuits |
| Viewing angle | ±60° - enables wide-angle uniform backlighting without secondary optics in switch or LCD applications |
| Junction temperature | +125°C max - sets thermal derating limits for continuous operation in enclosed automotive environments |
| ESD withstand | 2 kV HBM - ensures robustness during handling and automated PCB assembly |
| AEC-Q101 qualified | Yes - validates reliability for automotive-grade use in dashboards and control panels |
Pinout & Package
VLRE31R1S1-GS18 uses a reverse gullwing SMD package with two terminals: anode and cathode. The package features low-profile thermoplastic body with white reflector cavity and clear epoxy lens, optimized for top-down emission through the PCB substrate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive LED terminal | Connected to constant-current source; polarity must be observed to avoid reverse-bias damage beyond 5 V |
| Cathode | Ground/negative LED terminal | Typically tied to system ground or current-sink driver; enables PCB-side thermal path via pad |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables precise optical coupling to light pipes and edge-lit LCD backlights without intensity loss |
| Luminous intensity ratio IVmax/IVmin > 1.6 | Ensures tight brightness consistency within each tape reel, reducing post-assembly calibration effort |
| JEDEC level 2 preconditioning | Guarantees moisture sensitivity compliance for standard reflow processes without baking requirement |
| Low profile SMD package | Minimizes Z-height for space-constrained designs such as thin dashboards and compact office equipment |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal cycling, vibration, and humidity stress conditions |
Applications
| Automotive Dashboard Backlighting | Office Equipment Indicators |
|---|---|
Use Scenario: Illuminating segmented symbols and analog gauge markings in instrument clusters. IC Role / Device Role / Timing Role: Light source emitting through PCB into light guide or diffuser film.

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 vs. 582–594 nm | Better suited for applications requiring higher brightness or tighter wavelength control (X/Y bins) | Select when tighter chromaticity grouping or higher minimum intensity is required; same package and drive conditions |
| OSRAM LYT776-R1S2 | Same luminous intensity bin (R1), comparable yellow spectrum, but different thermal resistance and packaging dimensions | Requires layout verification due to non-identical footprint and thermal pad design | Consider for second-source procurement where OSRAM supply chain alignment is preferred; not pin-compatible |
Compared with VLRE31R1S1-GS18, VLRE31R2S2-XY-GS08 offers higher minimum intensity and narrower wavelength tolerance, while LYT776-R1S2 provides cross-manufacturer availability at the cost of mechanical redesign validation.
