Product details
Overview
VLMK3105-GS08 from Vishay Semiconductors is a red AlInGaP-on-GaAs surface-mount LED in PLCC-2 package, delivering 35.5–90 mcd luminous intensity at 10 mA, with dominant wavelength of 630 nm, forward voltage of 1.9–2.6 V at 20 mA, and ±60° viewing angle. It serves as a high-brightness indicator or backlighting source in automotive dashboards and office equipment.
For engineers reviewing the VLMK3105-GS08 datasheet, VLMK3105-GS08 pinout, VLMK3105-GS08 application, or VLMK3105-GS08 equivalent, this page provides verified optical, electrical, thermal, and packaging data - including JEDEC level 2a preconditioning, AEC-Q101 qualification, and IR reflow compatibility - to support SMT design, brightness binning selection, and automotive-grade reliability validation.
Technical Context
The VLMK3105-GS08 uses AlInGaP-on-GaAs die technology optimized for high-efficiency red emission at 630 nm dominant wavelength and 643 nm peak wavelength. Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and internal reflector, enabling non-diffused light output ideal for light-pipe coupling.
Rated for 30 mA DC forward current and 125 °C junction temperature, it exhibits 400 K/W thermal resistance (junction-to-ambient on >16 mm² PCB pad) and 15 pF junction capacitance at 0 V/1 MHz. Reverse voltage rating is 5 V, with ESD withstand up to 2 kV per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 35.5–90 mcd at 10 mA - defines brightness bin N2 for consistent visual output across reels |
| Dominant wavelength | 630 nm - ensures stable red chromaticity for human-visible indicators and backlighting |
| Forward voltage | 1.9–2.6 V at 20 mA - enables low-power operation with standard 3.3 V or 5 V logic-level drive |
| Viewing angle | ±60° - supports wide-angle illumination without secondary optics in panel indicators |
| Junction temperature | 125 °C - allows continuous operation in under-hood automotive environments up to +100 °C ambient |
| Thermal resistance | 400 K/W - requires ≥16 mm² copper pad for thermal management in high-duty-cycle applications |
| ESD rating | 2 kV HBM - meets IEC 61000-4-2 Level 2 for handling in automated SMT lines |
Pinout & Package
Package: PLCC-2 (equivalent to size B tantalum capacitor), 3.5 mm × 2.8 mm × 1.75 mm body, with 2.2 mm lead spacing and 0.9 mm thickness. Lead frame embedded in white thermoplastic; non-diffused clear epoxy lens.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source; polarity must be observed to avoid reverse conduction beyond 5 V |
| Cathode (K) | Ground/negative LED terminal | Common return path; soldered to ground plane or current-sink driver output |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use, including dashboard backlighting and switch indicators |
| Luminous intensity ratio ≤1.6 | Ensures tight brightness matching within a reel (IVmax/IVmin ≤ 1.6), reducing post-assembly calibration |
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit LCD backlights without scattering loss |
| JEDEC level 2a preconditioning | Guarantees moisture sensitivity compliance for Pb-free reflow up to 260 °C peak |
| Low profile (1.75 mm height) | Fits space-constrained front-panel designs and thin bezel assemblies |
Applications
| Automotive Dashboard Backlighting | Office Equipment Indicator |
|---|---|
Use Scenario: Illuminating segmented symbols and icons on instrument cluster overlays. IC Role / Device Role / Timing Role: Discrete red light source driven by constant-current LED driver ICs (e.g., AS1107, TPS6106x). Use Value: High luminous intensity (35.5–90 mcd) ensures visibility under direct sunlight; AEC-Q101 qualification guarantees long-term reliability in thermal cycling environments. |
Use Scenario: Status indication on printers, scanners, and multifunction devices. IC Role / Device Role / Timing Role: Standalone visual feedback element controlled via GPIO or shift-register outputs. Use Value: Tight luminous intensity binning (N2 group) eliminates manual brightness sorting during manufacturing; PLCC-2 footprint supports high-speed pick-and-place placement. |
| Telecom Device Backlighting | Audio/Video Equipment Indicator |
Use Scenario: Edge-lit keypad backlighting in VoIP phones and fax machines. IC Role / Device Role / Timing Role: Primary red emitter coupled directly to molded light guides. Use Value: Non-diffused lens and ±60° viewing angle maximize coupling efficiency into narrow light pipes; low forward voltage reduces power supply burden in battery-backed systems. |
Use Scenario: Power-on and signal-activity indicators on AV receivers and amplifiers. IC Role / Device Role / Timing Role: Direct-drive LED from microcontroller GPIO pins with series resistor. Use Value: 1.9–2.6 V forward voltage range allows robust operation across process and temperature variation; ESD rating of 2 kV prevents field failures during service. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LST676 | Same dominant wavelength (630 nm), but luminous intensity range 25–70 mcd at 10 mA - lower max output than VLMK3105-GS08's 90 mcd | Approved for similar automotive and industrial indicator roles; lacks explicit AEC-Q101 documentation in public datasheet | Select when legacy OSRAM sourcing or cross-qualified supply chain is required; verify binning consistency separately |
| Vishay VLMK3102-GS08 | Same package and technology, but lower luminous intensity (22.4–56 mcd) - corresponds to M2 brightness bin | Suitable for lower-brightness indicator roles where glare reduction or power savings are prioritized | Choose for cost-sensitive designs where 50 mcd typical output suffices; shares identical footprint and thermal behavior |
Compared with VLMK3105-GS08, the LST676 offers comparable spectral performance but less peak brightness and unconfirmed AEC-Q101 status, while the VLMK3102-GS08 provides identical reliability and form factor at reduced intensity - enabling brightness-tiered BOM optimization without layout changes.

FAQ
What is the maximum forward current rating for VLMK3105-GS08?
The absolute maximum DC forward current for VLMK3105-GS08 is 30 mA at ambient temperatures ≤85 °C. Operation above this value risks accelerated degradation or thermal runaway. For continuous duty, derating per Figure 1 is required - e.g., 22 mA at 100 °C ambient. The VLMK3105-GS08 must not exceed its 80 mW power dissipation limit, calculated as IF × VF.
Is VLMK3105-GS08 compatible with lead-free reflow soldering processes?
Yes, VLMK3105-GS08 is qualified for Pb-free reflow per J-STD-020, supporting peak package body temperatures up to 260 °C for ≤10 seconds. Its JEDEC level 2a preconditioning ensures moisture sensitivity compliance. The recommended profile includes ramp rates ≤3 °C/s (up) and ≤6 °C/s (down), with 217–245 °C liquidus time ≤60 s. The VLMK3105-GS08 must be baked if exposed to >60 % RH for >672 hours after bag opening.
What does the "GS08" suffix indicate in VLMK3105-GS08?
The "GS08" suffix denotes Vishay's 8 mm antistatic blister tape packaging option containing 1,500 units per reel. This format is optimized for high-speed SMT placement equipment and complies with DIN IEC 40 (CO) 564. GS08 differs from GS18 (8,000 units/reel) in tape width, cavity depth, and reel dimensions - the VLMK3105-GS08 is not interchangeable with GS18 without feeder adjustment.
How is luminous intensity binned for VLMK3105-GS08?
VLMK3105-GS08 is categorized in the N2 luminous intensity group (35.5–45.0 mcd), one of two sub-bins within the N group. Each reel ships only one brightness bin - no mixing occurs. The VLMK3105-GS08's IVmax/IVmin ratio is ≤1.6, ensuring minimal visual variation across LEDs on the same reel. Brightness binning is measured at 10 mA pulse (25 ms) with ±11 % accuracy.
Does VLMK3105-GS08 require special ESD handling during assembly?
Yes, VLMK3105-GS08 has a 2 kV HBM ESD rating per JESD22-A114-B, but still requires standard ESD controls: grounded workstations, ionizers, antistatic bags, and wrist straps. The device is shipped in moisture-barrier dry packs with JESD22-A112 level 2a labels. After opening, store in <10 % RH dry boxes or bake before reflow if exposed to >60 % RH for >672 hours. Failure to observe these steps may cause latent damage to the VLMK3105-GS08.
