Product details
Overview
VLMY3101-GS08 from Vishay Semiconductors is a surface-mount yellow LED in PLCC-2 package, featuring dominant wavelength 581–594 nm, luminous intensity 4.5–11.2 mcd at 10 mA, forward voltage 2.1–2.8 V at 20 mA, ±60° viewing angle, and GaAsP-on-GaP chip technology - used for indicator and backlighting in office equipment and LCD panels.
For engineers reviewing the VLMY3101-GS08 datasheet, VLMY3101-GS08 pinout, VLMY3101-GS08 application, or VLMY3101-GS08 equivalent, this page delivers verified optical, electrical, thermal, and packaging data - including JEDEC level 2a preconditioning compliance, 8 mm tape packaging, and PLCC-2 mounting pad layout - to support SMT design, brightness binning validation, and reflow process integration.
Technical Context
This yellow LED uses GaAsP-on-GaP semiconductor technology with non-diffused lens for high-directional coupling to light pipes and backlighting assemblies. Its PLCC-2 thermoplastic package embeds a lead frame and white reflector filled with clear epoxy, enabling compatibility with infrared, vapor-phase, and wave soldering per CECC 00802 and J-STD-020.
Rated for DC forward current up to 20 mA at ≤74 °C ambient, it delivers stable luminous output across -40 to +100 °C operating range with thermal resistance junction-to-ambient of 400 K/W on ≥16 mm² PCB pads. Luminous intensity ratio within one reel is controlled to IVmax/IVmin ≤ 1.6 per JEDEC-compliant binning.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMY3100-GS08 | Lower luminous intensity (2.8–11 mcd vs. 4.5–11.2 mcd); same wavelength, VF, and package. | Suitable where reduced brightness suffices for lower power or glare-sensitive environments. | Select when tighter luminance control at lower end of yellow bin is required; identical footprint and drive conditions. |
| VLMY3102-GS08 | Higher luminous intensity (7.1–18 mcd vs. 4.5–11.2 mcd); otherwise identical optical/electrical specs. | Better suited for high-ambient-light environments or longer viewing distances. | Choose for enhanced visibility in bright rooms or outdoor-adjacent enclosures; no layout or driver changes needed. |

FAQ
What is the dominant wavelength range of the VLMY3101-GS08?
The VLMY3101-GS08 has a dominant wavelength range of 581–594 nm, measured at 10 mA forward current. This places its emission squarely in the yellow portion of the visible spectrum, optimized for high photopic sensitivity and compatibility with standard yellow indicator requirements per IEC 60417. The value is confirmed in the "VLMY310., YELLOW" section of Vishay document 84789, Rev. 2.6.
What is the maximum DC forward current rating for VLMY3101-GS08?
The VLMY3101-GS08 is rated for a maximum DC forward current of 20 mA at ambient temperatures ≤74 °C. Exceeding this current without derating risks exceeding the 100 °C junction temperature limit and accelerated lumen depreciation. This absolute maximum rating is specified in the "ABSOLUTE MAXIMUM RATINGS" table on page 2 of Vishay document 84789.
Does VLMY3101-GS08 require baking before reflow soldering?
No - the VLMY3101-GS08 is preconditioned to JEDEC level 2a and shipped in moisture-barrier packaging with appropriate labeling. It may be placed directly into standard Pb-free reflow profiles (peak 245–260 °C) within 672 hours of bag opening at ≤30 °C/60 % RH. Baking is only required if humidity exposure exceeds these limits, per Vishay's dry packing guidelines in document 84789, page 11.
What is the luminous intensity binning tolerance for VLMY3101-GS08?
Within a single 1500-unit GS08 tape reel, the VLMY3101-GS08 maintains a luminous intensity ratio of IVmax/IVmin ≤ 1.6. This tight binning ensures consistent brightness across all units on the reel, critical for uniform appearance in multi-LED arrays or mass-produced indicator panels. The specification is documented in Note (1) on pages 2 and 3 of Vishay document 84789.
Is VLMY3101-GS08 compatible with wave soldering processes?
Yes - the VLMY3101-GS08 is qualified for wave soldering per CECC 00802, with a maximum soldering temperature of 260 °C for ≤5 seconds. Its PLCC-2 thermoplastic package and lead frame construction withstand thermal shock and wetting forces typical of double-wave processes, as confirmed in the "FEATURES" section and "SOLDERING PROFILE" figures (28) of Vishay document 84789.
