Product details
Overview
VLMD3105-GS08 from Vishay Semiconductors is a red surface-mount LED in PLCC-2 package, featuring luminous intensity of 11.2–28 mcd at 10 mA, dominant wavelength of 648 nm, ±60° viewing angle, and forward voltage of 1.8–2.2 V at 20 mA. It is designed for automotive dashboard backlighting, telecom indicators, and LCD flat backlighting where narrow brightness binning (IVmax/IVmin ≤ 1.6 per reel) and AEC-Q101 qualification are required.
For engineers reviewing the VLMD3105-GS08 datasheet, VLMD3105-GS08 pinout, VLMD3105-GS08 application, or VLMD3105-GS08 equivalent, this page delivers verified optical-electrical specs, PLCC-2 terminal mapping, AEC-Q101 compliance context, and direct alternatives with documented luminous intensity and wavelength alignment.
Technical Context
The VLMD3105-GS08 uses GaAlAs-on-GaAs technology to deliver stable red emission with dominant wavelength tightly binned at 648 nm (typ.) and peak wavelength at 650 nm (typ.). Its PLCC-2 package integrates a white thermoplastic lead frame and clear epoxy lens, enabling non-diffused light output optimized for coupling into light pipes and uniform backlight panels.
Thermal design is constrained by RthJA = 400 K/W (on >16 mm² PCB pad), junction temperature limit of 100 °C, and absolute max DC forward current of 30 mA at Tamb ≤ 60 °C. ESD withstand voltage reaches 2 kV (HBM, JESD22-A114-B), and preconditioning complies with JEDEC level 2a for moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 11.2–28 mcd at 10 mA - ensures consistent brightness within tight binning group M (18–28 mcd) |
| Dominant wavelength | 648 nm (typ.) - precise red chromaticity for automotive and indicator color-matching requirements |
| Viewing angle | ±60° - wide, symmetric beam pattern suitable for uniform area illumination without secondary optics |
| Forward voltage | 1.8–2.2 V at 20 mA - low-power operation compatible with 3.3 V and 5 V logic-supplied LED drivers |
| Reverse voltage | 6 V - sufficient margin for transient protection in automotive and industrial signal lines |
| Junction capacitance | 7 pF at 0 V, 1 MHz - minimal capacitive loading for high-speed multiplexed display driving |
| ESD rating | 2 kV HBM - meets IEC 61000-4-2 Level 2 for handling robustness in automated SMT lines |
Pinout & Package
VLMD3105-GS08 is housed in a standard SMD PLCC-2 package (4.1 × 3.9 mm footprint, 1.6 mm height) with molded white thermoplastic body and non-diffused clear epoxy lens. The package conforms to EIA/ICE standards and supports IR reflow, vapor phase, and wave soldering per J-STD-020 and CECC 00802.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source or driver high-side; polarity must be observed to avoid reverse conduction beyond 6 V |
| Cathode (K) | Negative LED terminal | Connected to ground or driver low-side; enables common-cathode multiplexing in multi-segment displays |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and cabin applications including dashboard backlighting and switch illumination |
| Luminous intensity ratio ≤ 1.6 per reel | Guarantees brightness consistency across 7500-unit GS08 tape-critical for uniform panel appearance |
| Non-diffused lens | Enables efficient coupling into light guides and edge-lit LCD backlights without intensity loss from scattering |
| JEDEC level 2a preconditioning | Ensures safe reflow processing without popcorning; dry pack labeling confirms moisture sensitivity level |
| Low profile (1.6 mm height) | Supports ultra-thin device designs such as slim keyboards, compact telecom handsets, and space-constrained instrument clusters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMD31L2N1-GS08 | Luminous intensity: 14–35.5 mcd (group N); same λd = 648 nm, VF = 1.8–2.2 V, PLCC-2 package | Higher brightness tier suitable for outdoor-readable indicators or higher ambient light environments | Select when >28 mcd minimum intensity is required; otherwise VLMD3105-GS08 offers tighter binning control (M group vs. N group) |
| OSRAM LHT674-L2N1 | Same luminous intensity range (14–35.5 mcd), identical PLCC-2 footprint, λd = 645 nm, VF = 1.9–2.3 V | Direct cross-reference per Vishay's official crossing table; validated for AEC-Q101 automotive use | Choose for multi-source procurement strategy; requires verification of 645 nm vs. 648 nm color tolerance in final optical stack |
Compared with VLMD3105-GS08, VLMD31L2N1-GS08 provides higher minimum intensity but looser binning (IVmax/IVmin ≤ 2.5), while OSRAM LHT674-L2N1 matches form-fit-function closely but shifts dominant wavelength by 3 nm-requiring optical recalibration in color-critical systems.

FAQ
What is the luminous intensity range of the VLMD3105-GS08 at 10 mA?
The VLMD3105-GS08 has a luminous intensity range of 11.2–28 mcd at 10 mA, corresponding to bin group M per Vishay's classification table. This range ensures consistent brightness across reels (IVmax/IVmin ≤ 1.6), making VLMD3105-GS08 ideal for uniform backlighting where visible intensity variation must be minimized.
Is the VLMD3105-GS08 qualified for automotive applications?
Yes, the VLMD3105-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive electronic components. This qualification supports its use in dashboard backlighting and switch illumination within passenger vehicles, as confirmed in the official Vishay datasheet revision 2.2.
What is the package type and mounting compatibility of the VLMD3105-GS08?
The VLMD3105-GS08 uses a standard SMD PLCC-2 package (4.1 × 3.9 mm, 1.6 mm height) with anode and cathode terminals clearly marked. It is compatible with automatic placement equipment and supports IR reflow, vapor phase, and wave soldering per J-STD-020 and CECC 00802-enabling seamless integration into high-volume SMT lines.
Does the VLMD3105-GS08 have a diffused or non-diffused lens?
The VLMD3105-GS08 features a non-diffused lens filled with clear epoxy, as specified in the Vishay datasheet. This optical design preserves directional output and maximizes coupling efficiency into light pipes and edge-lit LCD backlights-unlike diffused LEDs that scatter light and reduce system optical efficiency.
What is the maximum allowable forward current for continuous operation of the VLMD3105-GS08?
The absolute maximum DC forward current for VLMD3105-GS08 is 30 mA at ambient temperatures ≤ 60 °C. At higher temperatures, derating applies per Figure 1 in the datasheet; for example, at 85 °C ambient, the permissible DC current drops to approximately 18 mA to maintain junction temperature ≤ 100 °C.
