Product details
Overview
VLRK31R1S2-GS08 from Vishay Semiconductors is a surface-mount red LED using AlInGaP-on-GaAs technology, delivering 112–285 mcd luminous intensity at 20 mA, with dominant wavelength 620–635 nm and forward voltage 2.1–2.3 V. It features reverse gullwing SMD packaging, ±60° viewing angle, and AEC-Q101 qualification for automotive backlighting.
For engineers reviewing the VLRK31R1S2-GS08 datasheet, VLRK31R1S2-GS08 pinout, VLRK31R1S2-GS08 application, or VLRK31R1S2-GS08 equivalent, key selection criteria include luminous intensity binning (S-group), thermal resistance (400 K/W), ESD rating (2 kV), IR reflow compatibility, and non-diffused lens suitability for light-pipe coupling.
Technical Context
This device operates as a top-down emitting SMD LED mounted on PCBs, with light emission directed through the board substrate. Its thermoplastic white reflector cavity and clear epoxy encapsulation optimize optical efficiency and directional control.
The VLRK31R1S2-GS08 is rated for DC forward current up to 30 mA and surge current up to 1 A (10 μs), with junction temperature limited to +125 °C and operating ambient range of −40 to +100 °C. Thermal resistance junction-to-ambient is 400 K/W when mounted on ≥16 mm² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 112–285 mcd at 20 mA - defines brightness binning (S-group) for consistent visual output across production reels |
| Dominant wavelength | 620–635 nm - ensures red spectral output compliant with automotive dashboard color standards |
| Forward voltage | 2.1–2.3 V at 20 mA - enables low-power operation with standard 3.3 V or 5 V logic-level drive circuits |
| Viewing angle | ±60° - provides wide, uniform illumination suitable for switch and symbol backlighting without secondary optics |
| ESD withstand | 2 kV HBM per JESD22-A114-B - supports handling in standard electronics assembly environments without special grounding |
| Junction-to-ambient Rth | 400 K/W on ≥16 mm² pad - determines maximum continuous current derating above 25 °C ambient |
| AEC-Q101 qualified | Validated for automotive-grade reliability - required for dashboard, HVAC, and infotainment indicator applications |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source; polarity must be observed-reverse bias limited to 5 V per absolute max rating |
| Cathode (K) | Negative LED terminal | Connected to ground or current sink; reverse mounting enables bottom-side emission through PCB |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit LCD backlights without optical loss from scattering |
| Luminous intensity ratio IVmax/IVmin > 1.6 | Ensures tight brightness consistency within each tape reel-no mixing of intensity bins per JEDEC packaging rules |
| IR reflow compatible | Rated for Pb-free reflow per J-STD-020C up to 260 °C peak, supporting high-volume automated SMT assembly |
| Low power consumption | 2.3 V × 20 mA = 46 mW typical dissipation - reduces thermal load in dense indicator arrays and battery-powered devices |
| Preconditioned per JEDEC Level 2 | Qualified for moisture sensitivity level (MSL) 2 - requires dry storage after bag opening to avoid popcorning during reflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LST776-R1S2 | OSRAM equivalent; identical luminous intensity bin (S-group), same 620–635 nm wavelength, but slightly higher VF typ. 2.25 V vs. 2.1–2.3 V | Same automotive and industrial indicator use cases; validated in OSRAM reference designs for telecom keypad backlighting | Select LST776-R1S2 when dual-sourcing from OSRAM is required; verify thermal layout due to minor VF shift affecting power dissipation |
| VLRK31Q1R2-GS08 | Vishay sibling part with lower luminous intensity (71–180 mcd Q-group), otherwise identical package, wavelength, and electrical specs | Suitable where reduced brightness suffices-e.g., low-ambient-light office indicators or cost-sensitive consumer products | Choose VLRK31Q1R2-GS08 to reduce system power or meet tighter BOM cost targets without changing PCB layout or drive circuitry |
Compared with VLRK31R1S2-GS08, LST776-R1S2 offers second-source assurance with near-identical optical performance but marginally higher forward voltage, while VLRK31Q1R2-GS08 provides a lower-brightness, cost-optimized variant within the same qualified platform and footprint.

FAQ
What is the luminous intensity range of the VLRK31R1S2-GS08?
The VLRK31R1S2-GS08 has a luminous intensity range of 112–285 mcd at 20 mA forward current, corresponding to the "S" brightness bin per Vishay's classification table. This binning ensures consistent visual output across production reels, with no mixing of intensity groups within a single GS08 tape reel containing 2000 units.
Is the VLRK31R1S2-GS08 suitable for automotive applications?
Yes, the VLRK31R1S2-GS08 is AEC-Q101 qualified and rated for operating temperatures from −40 to +100 °C, making it suitable for automotive dashboard backlighting, HVAC controls, and infotainment indicators. Its thermoplastic white reflector and clear epoxy construction support long-term reliability under thermal cycling and vibration conditions.
What is the package type and mounting orientation of the VLRK31R1S2-GS08?
The VLRK31R1S2-GS08 uses a reverse gullwing SMD package with top-down LED die mounting, emitting light through the PCB substrate. Its JEDEC-compliant footprint measures 2.7 mm × 1.2 mm × 0.8 mm, with 1.27 mm lead pitch and low-profile design optimized for space-constrained layouts and automated placement.
Does the VLRK31R1S2-GS08 require special handling during PCB assembly?
Yes-the VLRK31R1S2-GS08 is moisture-sensitive (MSL Level 2 per JEDEC J-STD-020C) and shipped in dry-packed anti-humidity bags. After opening, it must be stored in a dry box (<5% RH) or baked per Vishay's guidelines (e.g., 96 h at 60 °C) before IR reflow to prevent popcorning damage during soldering.
What is the dominant wavelength and viewing angle specification for the VLRK31R1S2-GS08?
The VLRK31R1S2-GS08 has a dominant wavelength of 620–635 nm (red spectrum) and a viewing angle of ±60°, measured at half-intensity. This wide, symmetric angular distribution enables uniform illumination of symbols and switches without requiring secondary lenses or diffusers in most indicator applications.
