Product details
Overview
VLMO3101-GS18 from Vishay Semiconductors is a surface-mount soft orange LED in PLCC-2 package, delivering 4.5–10 mcd luminous intensity at 10 mA, with dominant wavelength 598–611 nm and ±60° viewing angle-designed for indicator and backlighting applications in office equipment and audio/video interfaces.
For engineers reviewing the VLMO3101-GS18 datasheet, VLMO3101-GS18 pinout, VLMO3101-GS18 application, or VLMO3101-GS18 equivalent, this page provides verified optical/electrical specs, SMD mounting compatibility, JEDEC Level 2a preconditioning compliance, and tape-and-reel packaging details (GS18 = 8000 pcs/reel).
Technical Context
The VLMO3101-GS18 uses GaAsP-on-GaP semiconductor technology to emit soft orange light with peak wavelength at 605 nm and dominant wavelength tightly binned per JEDEC-compliant color classification. Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and non-diffused optics optimized for light-pipe coupling and flat backlighting.
Rated for 20 mA DC forward current and 6 V reverse voltage, it operates across –40 °C to +100 °C ambient temperature, with thermal resistance of 400 K/W (mounted on >16 mm² PCB pad) and junction temperature limit of 100 °C-enabling reliable use in high-density SMT assemblies subject to IR reflow, vapor-phase, or wave soldering per J-STD-020 and CECC 00802.

Use Value: Non-diffused lens minimizes coupling loss into light pipe, achieving >85% optical transfer efficiency vs. diffused alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMO3100-GS08 | Luminous intensity 2.8–8 mcd (lower output); GS08 tape = 1500 pcs/reel | Suitable for low-brightness indicator roles where power budget is constrained | Select when lower intensity suffices and smaller reel quantities are preferred for prototyping |
| VLMY3101-GS08 | Yellow emission (581–594 nm dominant wavelength); identical intensity range (4.5–11.2 mcd) | Used where color-coding requires yellow instead of soft orange per UI design standards | Choose for color-matching in multi-LED status arrays where spectral distinction matters |
Compared with VLMO3101-GS18, VLMO3100-GS08 offers reduced brightness in a smaller reel format, while VLMY3101-GS08 substitutes yellow chromaticity without compromising intensity-both retain identical PLCC-2 mechanical fit and soldering compatibility.

FAQ
What is the dominant wavelength range of the VLMO3101-GS18?
The VLMO3101-GS18 has a dominant wavelength range of 598–611 nm, placing its emission in the soft orange spectrum. This value is measured at 10 mA forward current and is binned per Vishay's color classification table to ensure consistency within each reel. The peak wavelength is specified at 605 nm, confirming spectral centering for optimal human-eye sensitivity in indicator applications.
Does the VLMO3101-GS18 require baking before reflow soldering?
Yes-the VLMO3101-GS18 is moisture-sensitive and preconditioned to JEDEC Level 2a. If the sealed aluminum bag is opened and the reel is stored at <30°C/60% RH, it must be mounted within 672 hours or baked per JESD22-A112: 96 h at 60°C ±5°C and <5% RH. Baking restores safe reflow capability by removing absorbed moisture that could cause popcorning during peak-temperature exposure.
What is the maximum continuous forward current rating for VLMO3101-GS18?
The absolute maximum DC forward current for VLMO3101-GS18 is 20 mA at ambient temperatures ≤74°C. Exceeding this rating risks accelerated degradation and reduced lumen maintenance. For continuous operation at full brightness, Vishay recommends derating to ≤15 mA above 74°C, per the "Maximum Permissible Forward Current vs. Ambient Temperature" curve in Figure 1 of the datasheet.
Is the VLMO3101-GS18 compatible with lead-free reflow processes?
Yes-VLMO3101-GS18 is qualified for lead-free reflow soldering per J-STD-020, with a peak package body temperature limit of 260°C for ≤10 seconds. The recommended profile (Figure 27) specifies ramp rates ≤3°C/s (up), soak at 150–200°C for 60–120 s, and time above liquidus (217°C) of ≤30 s. It also supports vapor-phase and double-wave soldering per CECC 00802.
How does the luminous intensity ratio IVmax/IVmin ≤ 1.6 affect system design?
This ratio guarantees that all VLMO3101-GS18 units on a single reel exhibit luminous intensity variation no greater than 1.6×-critical for uniform appearance in multi-LED arrays. Designers can eliminate per-LED calibration or binning steps in production, reducing firmware complexity and test time. It also simplifies brightness matching in stacked or side-by-side indicator layouts without manual sorting.
