| Forward Voltage (Vf) | 2.1 V (typical) | IEC 60747-5-5 |
| Wavelength | 616 nm (amber) | CIE 1931 Chromaticity |
| Luminous Intensity | 550 mcd | LM-80 Testing |
| Viewing Angle | 120° | Vishay MiniLED Series Spec |
| Operating Temperature | -40°C to +100°C | AEC-Q101 Qualified |
| Package Size | 2.2 x 1.4 x 1.3 mm | JEDEC MO-229 |
When choosing between SMD LEDs like the VLMK235T2V1-GS08, consider these factors:
Brightness Requirements: 550mcd suits medium-brightness needs (e.g., indicators). For higher intensity, consider Vishay's VLMx334 series (up to 1200mcd).
Color Accuracy: The 616nm wavelength ensures consistent amber output, critical for traffic signals per ITE MUTCD standards.
Environmental Conditions: AEC-Q101 qualification makes this LED ideal for automotive applications where temperature fluctuations occur.
Power Efficiency: At 2.1V forward voltage, it consumes ~105mW at 50mA, balancing brightness and energy use.
Package Size: The 2.1x1.4mm footprint fits space-constrained designs like wearable devices.
Traffic Signals & Signs: Complies with EN 12368 visibility standards due to 120° viewing angle and color consistency.
Automotive Dashboard Lighting: AEC-Q101 qualification ensures reliability under hood temperatures.
Industrial Control Panels: Non-diffused lens provides clear status indication in factory automation.
Consumer Electronics: Used in backlighting for buttons/switches in audio/video equipment.
Medical Devices: Amber color reduces eye strain in low-light environments (e.g., hospital equipment).
According to Strategies Unlimited (2023), the global SMD LED market will grow at 6.8% CAGR through 2027, driven by:
Automotive LED adoption (projected to reach $5.2B by 2025, Yole Développement)
Smart city infrastructure requiring energy-efficient traffic lights
Miniaturization trends favoring compact packages like the VLMK235T2V1-GS08
Vishay’s MiniLED series holds ~12% market share in industrial/automotive segments (Omdia 2023).

|---|---|---|---|---|
| Luminous Intensity | 550 mcd | 300 mcd | 800 mcd | Balanced brightness for power efficiency |
| Viewing Angle | 120° | 60° | 140° | Wider than Kingbright, ideal for signage |
| Temperature Range | -40°C to +100°C | -30°C to +85°C | -40°C to +85°C | Superior high-temp performance |
| Qualification | AEC-Q101 | None | AEC-Q101 | Cost-effective vs. OSRAM |
Yes, its -40°C to +100°C operating range and 2kV ESD protection (per JESD22-A114-B) make it resilient in outdoor environments.
Absolutely. The 2.1V forward voltage minimizes power consumption, extending battery life in portable electronics.
Wider than many SMD LEDs (e.g., Kingbright’s 60°), ensuring visibility from multiple angles—critical for traffic applications.
Yes, it’s compatible with JEDEC J-STD-020 reflow profiles (preconditioned to Level 2a).
Over 50,000 hours at 20mA (per LM-80 testing), assuming proper thermal management.
The VLMK235T2V1-GS08 aligns with three key industry shifts:
Automotive ADAS Growth: Increasing amber LED demand for dashboard warnings (projected 9.1% CAGR, McKinsey 2023).
UV-C Disinfection: Vishay’s AlInGaP tech may expand into germicidal applications.
Miniaturization: Smaller packages (e.g., 1.0x0.5mm) could emerge while maintaining brightness.
