Product details
Overview
VLMY31K1L2-GS08 from Vishay Semiconductors is a yellow surface-mount LED in PLCC-2 package, designed for narrow-brightness and color-bin applications with luminous intensity of 7.1–18 mcd at 10 mA, dominant wavelength 581–594 nm, and ±60° viewing angle. It serves as an indicator or backlight in telecommunication, audio/video, and office equipment requiring stable optical output and IR-reflow compatibility.
For engineers reviewing the VLMY31K1L2-GS08 datasheet, VLMY31K1L2-GS08 pinout, VLMY31K1L2-GS08 application, or VLMY31K1L2-GS08 equivalent, key selection criteria include its luminous intensity bin (K1/L2), GaAsP-on-GaP technology, 2.1–2.8 V forward voltage at 20 mA, ESD rating of 2 kV, and PLCC-2 footprint compatibility with automated placement and reflow soldering per J-STD-020.
Technical Context
This device uses GaAsP-on-GaP semiconductor technology to emit yellow light with tightly binned dominant wavelength (581–594 nm) and luminous intensity (7.1–18 mcd at 10 mA). Its non-diffused lens enables efficient coupling to light pipes and LCD backlights, while the PLCC-2 thermoplastic package with white reflector and clear epoxy ensures high optical efficiency and thermal stability up to 100 °C junction temperature.
The VLMY31K1L2-GS08 operates within absolute maximum ratings of 20 mA DC forward current, 6 V reverse voltage, and 56 mW power dissipation. Its thermal resistance junction-to-ambient is 400 K/W when mounted on a PCB pad >16 mm², and it meets JEDEC level 2a preconditioning and EIA/ICE standard packaging requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 7.1–18 mcd at 10 mA - defines brightness range for consistent visual indication across production reels |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current-limiting resistor or constant-current driver output; polarity must be observed to avoid reverse breakdown |
| Cathode (K) | Negative terminal | Connected to ground or low-side switch; reverse voltage rating is only 6 V - not intended for bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | K1/L2 group (7.10–18.00 mcd) ensures consistent brightness across reels - no mixing of bins per tape |
| Non-diffused lens | Enables precise optical coupling to light guides and edge-lit LCDs without scattering loss |
| IR-reflow compatible | Rated for peak 260 °C exposure per J-STD-020 - supports standard Pb-free reflow profiles |
| JEDEC level 2a preconditioning | Validated moisture sensitivity level - requires dry storage or baking if exposed >672 h at ≤30 °C / 60 % RH |
| Low power consumption | 20 mA max operating current at 2.8 V - enables battery-powered or energy-sensitive indicator designs |

FAQ
What is the luminous intensity range of the VLMY31K1L2-GS08?
The VLMY31K1L2-GS08 has a luminous intensity range of 7.1–18 mcd at 10 mA, corresponding to the K1/L2 bin classification. This tight binning ensures consistent brightness across production reels, with no mixing of intensity groups per tape - critical for uniform visual appearance in multi-unit assemblies.
What is the dominant wavelength specification for VLMY31K1L2-GS08?
The dominant wavelength of VLMY31K1L2-GS08 is specified as 581–594 nm at 10 mA, placing it firmly in the yellow spectrum. This range is binned into six color groups (1–6), and VLMY31K1L2-GS08 falls within groups covering 581–594 nm - ensuring predictable hue for human-vision-critical applications.
Does VLMY31K1L2-GS08 support lead-free reflow soldering?
Yes, VLMY31K1L2-GS08 is qualified for lead-free reflow soldering per J-STD-020, with a peak package body temperature rating of 260 °C for ≤10 seconds. Its PLCC-2 package is compatible with IR reflow, vapor-phase, and wave soldering processes, and it meets JEDEC level 2a preconditioning requirements.
What is the maximum forward current rating for VLMY31K1L2-GS08?
The absolute maximum DC forward current for VLMY31K1L2-GS08 is 20 mA at ambient temperatures ≤60 °C. Exceeding this value risks accelerated degradation or thermal runaway; operation above 60 °C requires current derating per the datasheet's forward-current vs. ambient-temperature curve.
How is the VLMY31K1L2-GS08 packaged for automated assembly?
VLMY31K1L2-GS08 is supplied in antistatic 8 mm blister tape (tape code GS08), containing 1500 pieces per reel. The tape complies with DIN IEC 40 (CO) 564 and is compatible with standard pick-and-place equipment - supporting high-throughput SMT lines without manual handling.
