It serves as a high-brightness indicator or backlight source in automotive dashboards, telecom equipment, and LCD panels.
For engineers reviewing the VLME31Q2T1-GS08 datasheet, VLME31Q2T1-GS08 pinout, VLME31Q2T1-GS08 application, or VLME31Q2T1-GS08 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, PLCC-2 footprint details, luminous intensity binning (Q2 group), and direct Vishay cross-references for design-in and sourcing decisions.
Technical Context
This device uses AlInGaP-on-GaAs epitaxial technology to achieve high-efficiency yellow emission with narrow dominant wavelength spread (581–594 nm) and stable chromaticity across temperature. Its non-diffused lens enables precise light coupling into light pipes and edge-lit displays.
The PLCC-2 package features a white thermoplastic body with embedded lead frame and clear epoxy-filled reflector cavity, supporting IR reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802. Thermal resistance junction-to-ambient is 400 K/W on ≥16 mm² PCB pad.
Key Specifications

Pinout & Package
The VLME31Q2T1-GS08 is housed in a surface-mount PLCC-2 package with 2 terminals: anode and cathode. The package has a low-profile, non-diffused lens and white thermoplastic body with embedded lead frame and clear epoxy reflector cavity. Recommended footprint matches DIN-compliant SMD pad layout (2.6 mm × 1.6 mm pad size).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source or higher potential; polarity must be observed to avoid reverse breakdown (VR = 5 V max) |
| Cathode (K) | Negative terminal | Connected to ground or current sink; reverse conduction permitted only for short-term applications per datasheet note |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning (Q2 group) | 90–112 mcd range - enables predictable brightness grading for mixed-reel designs without post-assembly sorting |
| Non-diffused lens | Enables >85% coupling efficiency into light pipes and edge-lit LCD backlights - reduces optical loss vs. diffused alternatives |
| AEC-Q101 qualification | Validated for automotive dashboard and switch backlighting - meets extended temperature (-40 to +100 °C) and lifetime requirements |
| JEDEC Level 2a preconditioning | Supports standard moisture-sensitive device handling - allows up to 672 h factory storage before reflow without baking |
| PLCC-2 mechanical compatibility | EIA/ICE-standard footprint - ensures interoperability with automated pick-and-place systems and existing SMT lines |

FAQ
What is the luminous intensity range of the VLME31Q2T1-GS08?
The VLME31Q2T1-GS08 has a luminous intensity range of 90–355 mcd at 20 mA forward current, corresponding to the Q2 brightness bin (90–112 mcd minimum/maximum per reel). This binning ensures consistent output across units shipped together, critical for uniform backlighting in multi-LED assemblies. The VLME31Q2T1-GS08 datasheet confirms this specification under standard test conditions (25 ms pulse, ±11% measurement accuracy).
Is the VLME31Q2T1-GS08 qualified for automotive use?
Yes, the VLME31Q2T1-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive interior applications such as dashboard and switch backlighting. This qualification is explicitly stated in the Vishay datasheet revision 2.0 and applies directly to the VLME31Q2T1-GS08 part number.
What is the dominant wavelength of the VLME31Q2T1-GS08?
The dominant wavelength of the VLME31Q2T1-GS08 is specified as 581–594 nm at 20 mA, placing it firmly in the yellow spectral band. This range is measured per JEDEC standards and reflects the peak human-perceived hue, distinct from peak wavelength (590 nm typical). The VLME31Q2T1-GS08 uses AlInGaP-on-GaAs technology to achieve this stable, narrow-band yellow output.
Does the VLME31Q2T1-GS08 have a diffused or non-diffused lens?
The VLME31Q2T1-GS08 features a non-diffused lens, as confirmed in the Vishay datasheet under "Features" and "Optical Characteristics." This design maximizes directional light output for efficient coupling into light pipes and edge-lit LCD backlights, distinguishing it from diffused variants intended for wide-angle indicator use. The VLME31Q2T1-GS08 optical pattern shows a ±60° half-intensity angle consistent with non-diffused construction.
What is the maximum forward current rating for the VLME31Q2T1-GS08?
The absolute maximum DC forward current for the VLME31Q2T1-GS08 is 30 mA at ambient temperatures ≤85 °C, as defined in the Absolute Maximum Ratings table. Continuous operation above this limit risks accelerated degradation or thermal runaway. For reliable long-term performance, Vishay recommends operating the VLME31Q2T1-GS08 at 20 mA - the condition under which all key optical parameters (intensity, wavelength, VF) are characterized.
