Product details
Overview
VLMD31L2P1-GS08 from Vishay Semiconductors is a red surface-mount LED in PLCC-2 package, featuring dominant wavelength of 648 nm, luminous intensity of 45–56 mcd at 10 mA, forward voltage of 1.8–2.2 V at 20 mA, ±60° viewing angle, and AEC-Q101 qualification for automotive backlighting applications.
For engineers reviewing the VLMD31L2P1-GS08 datasheet, VLMD31L2P1-GS08 pinout, VLMD31L2P1-GS08 application, or VLMD31L2P1-GS08 equivalent, this device supports narrow-bin luminous intensity control (IVmax/IVmin ≤ 1.6 per reel), IR-reflow compatibility, and low-profile coupling to light pipes in dashboard and switch backlighting designs.
Technical Context
This GaAlAs-on-GaAs LED operates with DC forward current up to 30 mA at ≤60 °C ambient, delivering stable red emission with thermal coefficients of –1.8 mV/K for forward voltage and +0.05 nm/K for dominant wavelength. Its junction-to-ambient thermal resistance is 400 K/W on a >16 mm² PCB pad.
The device uses a non-diffused lens and white thermoplastic reflector filled with clear epoxy, enabling high-directional coupling efficiency. It meets JEDEC JESD22-A114-B ESD rating (2 kV) and CECC 00802/J-STD-020 soldering standards for automated placement and reflow processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LHT674-M2P1 | Same optical specs (648 nm, 45–56 mcd), identical PLCC-2 package, Osram-branded equivalent with matching binning structure | No functional difference; used interchangeably in automotive and industrial designs where dual-sourcing is required | Select when Osram supply chain alignment or cross-qualified procurement is mandated by OEM design requirements |
| VLMD31M2P1-GS08 | Identical package and wavelength, but lower luminous intensity range (22.4–56 mcd vs. 45–56 mcd); same AEC-Q101 qualification and thermal specs | Less stringent brightness consistency (IVmax/IVmin ≤ 2.5 vs. ≤ 1.6), suitable for non-critical indicator use where cost optimization is prioritized | Choose for cost-sensitive consumer applications where tighter luminance binning is not required |
Compared with VLMD31L2P1-GS08, LHT674-M2P1 offers identical performance and sourcing flexibility, while VLMD31M2P1-GS08 trades intensity consistency for broader availability and lower unit cost in non-automotive contexts.

FAQ
What is the luminous intensity range of VLMD31L2P1-GS08 and how is it binned?
The VLMD31L2P1-GS08 has a luminous intensity range of 45–56 mcd at 10 mA and belongs to Group P in Vishay's intensity classification table. Each reel contains only one brightness group (no mixing), with IVmax/IVmin ≤ 1.6 - ensuring tight consistency for uniform backlighting in automotive and display applications where visual matching is critical. This binning is verified per reel during manufacturing.
Is VLMD31L2P1-GS08 suitable for automotive applications?
Yes, VLMD31L2P1-GS08 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, humidity bias, and mechanical shock - confirming its suitability for automotive interior lighting such as dashboard symbols, switch backlighting, and center console indicators. Its 100 °C junction rating and ±60° viewing angle further support under-hood and cabin deployment.
What is the forward voltage specification for VLMD31L2P1-GS08 and how does it impact driver design?
VLMD31L2P1-GS08 has a forward voltage of 1.8–2.2 V at 20 mA. This low VF range allows direct drive from common 3.3 V or 5 V rails using simple current-limiting resistors, or integration with low-dropout LED drivers like the TPS61062. The narrow VF spread simplifies thermal compensation in constant-current designs and reduces power loss in high-channel-count backlight systems.
Can VLMD31L2P1-GS08 be used with standard lead-free reflow processes?
Yes, VLMD31L2P1-GS08 is fully compatible with lead-free IR reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802. Its package withstands peak temperatures up to 260 °C for ≤10 seconds, and it is preconditioned to JEDEC level 2a - making it suitable for high-volume SMT lines without special handling or baking requirements when stored properly in dry-packed reels.
What is the viewing angle and lens type of VLMD31L2P1-GS08, and why does it matter for backlighting?
VLMD31L2P1-GS08 features a ±60° viewing angle and a non-diffused lens. This combination delivers highly directional output ideal for coupling into light pipes, edge-lit LCD backlights, and small-aperture indicators - minimizing light loss and crosstalk. In dashboard backlighting, it ensures bright, focused illumination on translucent symbols without washing out adjacent elements.
