It is AEC-Q101 qualified and designed for automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLME31Q2T1-35-GS08 datasheet, VLME31Q2T1-35-GS08 pinout, VLME31Q2T1-35-GS08 application, or VLME31Q2T1-35-GS08 equivalent, key selection criteria include luminous intensity binning (Q2T1), yellow color consistency, PLCC-2 thermal resistance (400 K/W), and compatibility with IR reflow per J-STD-020C.
Technical Context
This device uses AlInGaP-on-GaAs epitaxial technology to achieve high-brightness yellow emission with narrow dominant wavelength spread (581–594 nm) and stable chromaticity across temperature. Its PLCC-2 thermoplastic package features a white reflector cavity and clear epoxy lens, enabling efficient light extraction and directional control.
The VLME31Q2T1-35-GS08 operates at 20 mA DC forward current (max 30 mA), supports surge currents up to 100 mA for ≤10 μs, and maintains luminous intensity ratio IVmax/IVmin ≤ 1.6 within a reel-ensuring consistent brightness matching for multi-LED arrays in backlighting systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLME31R1S2-GS08 | Higher min. luminous intensity (112 mcd vs. 90 mcd); same wavelength and VF range | Better suited for applications requiring higher baseline brightness without increasing drive current | Select when tighter lower-bound intensity is needed for low-current operation or aging margin |
| OSRAM LYT676-Q2T1 | Same luminous intensity bin (Q2T1), identical dominant wavelength spec, but different package thermal profile (RthJA = 380 K/W) | Compatible in footprint but requires validation of thermal performance in high-density layouts | Choose for dual-sourcing where OSRAM supply chain alignment is preferred, with attention to thermal derating |
Compared with VLME31Q2T1-35-GS08, VLME31R1S2-GS08 offers higher minimum brightness for improved low-light visibility, while LYT676-Q2T1 provides an alternate supply with near-identical optical specs but slightly better thermal resistance-both require verification of board-level thermal management and binning compliance.

FAQ
What is the luminous intensity range of the VLME31Q2T1-35-GS08 at 20 mA?
The VLME31Q2T1-35-GS08 has a luminous intensity range of 90–355 mcd at 20 mA forward current, corresponding to its Q2T1 bin classification. This range reflects factory-tested values under standardized pulse conditions (25 ms duration, ±11% measurement accuracy), and all units on a given reel fall within this ratio (IVmax/IVmin ≤ 1.6). The VLME31Q2T1-35-GS08 is specified for use in applications where consistent brightness matching matters, such as multi-LED backlight arrays.
Is the VLME31Q2T1-35-GS08 suitable for automotive applications?
Yes, the VLME31Q2T1-35-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and other environmental conditions required for automotive interior lighting. Its operating temperature range of -40°C to +100°C ambient, combined with AlInGaP-on-GaAs technology stability, makes it appropriate for dashboard backlighting and switch illumination. The VLME31Q2T1-35-GS08 meets these requirements without derating at typical cabin temperatures.
What is the maximum forward current rating for continuous operation of the VLME31Q2T1-35-GS08?
The absolute maximum DC forward current for the VLME31Q2T1-35-GS08 is 30 mA at ambient temperatures ≤85°C. For reliable long-term operation, Vishay recommends limiting continuous drive to 20 mA-the test condition for all published optical and electrical specifications-including luminous intensity, forward voltage, and wavelength. Exceeding 20 mA requires thermal analysis using the 400 K/W junction-to-ambient resistance and may reduce lifetime. The VLME31Q2T1-35-GS08 is not rated for pulsed operation beyond datasheet limits.
Does the VLME31Q2T1-35-GS08 have a diffused or non-diffused lens?
The VLME31Q2T1-35-GS08 features a non-diffused lens made of clear epoxy, optimized for coupling into light pipes and edge-lit backlight structures. This design minimizes lateral scattering and preserves luminance for directional applications like instrument cluster illumination. The non-diffused lens contributes to its ±60° viewing angle specification and supports high-efficiency light extraction. The VLME31Q2T1-35-GS08 is distinct from diffused variants that trade intensity for wider Lambertian distribution.
What soldering profiles are compatible with the VLME31Q2T1-35-GS08?
The VLME31Q2T1-35-GS08 is qualified for lead-free IR reflow per J-STD-020C, with peak temperature up to 260°C for ≤10 seconds, and also supports vapor-phase and wave soldering per CECC 00802. Its PLCC-2 package is JEDEC Level 2a preconditioned, allowing mounting within 672 hours of bag opening at ≤30°C/60% RH. The VLME31Q2T1-35-GS08 must not be subjected to moisture exposure beyond this window without baking per JESD22-A112 guidelines.
