Product details
Overview
VLME3101-GS18 from Vishay Semiconductors is a high-intensity yellow AlInGaP-on-GaAs SMD LED in PLCC-2 package, delivering 28–75 mcd luminous intensity at 10 mA, with dominant wavelength 581–594 nm and ±60° viewing angle. It is AEC-Q101 qualified and designed for automotive dashboard backlighting, office equipment indicators, and LCD flat backlighting.
For engineers reviewing the VLME3101-GS18 datasheet, VLME3101-GS18 pinout, VLME3101-GS18 application, or VLME3101-GS18 equivalent, this page provides verified optical/electrical specs, JEDEC level 2a preconditioning compliance, IR reflow compatibility, tape-and-reel packaging (8000 pcs/reel), and real-world design context for indicator and backlight use cases.
Technical Context
The VLME3101-GS18 operates as a low-power, non-diffused lens SMD LED optimized for efficient light coupling into light pipes and uniform panel backlighting. Its PLCC-2 package features a white thermoplastic body with embedded lead frame and clear epoxy-filled reflector cavity, enabling high thermal resistance control (RthJA = 400 K/W) and stable operation from –40 °C to +100 °C ambient.
It supports standard automated placement and soldering processes including Pb-free IR reflow (J-STD-020C compliant), vapor phase, and wave soldering (CECC 00802). Luminous intensity binning ensures IVmax/IVmin ≤ 1.6 within each reel, and wavelength grouping follows strict 6-bin classification (581–594 nm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 28–75 mcd at 10 mA - defines visible brightness level for human-perceivable indicators under standard drive conditions |
| Dominant wavelength | 581–594 nm - specifies yellow chromaticity suitable for high-contrast dashboard and switch illumination |
| Forward voltage | 2.0–2.6 V at 20 mA - determines minimum supply headroom and series resistor sizing for constant-current drive |
| Viewing angle | ±60° - enables wide-angle illumination without secondary optics, ideal for direct-panel backlighting |
| Junction temperature | +125 °C max - sets thermal derating limit for continuous DC operation in enclosed automotive environments |
| Reverse voltage | 5 V - defines maximum allowable reverse bias during multiplexed or AC-coupled driving schemes |
| Thermal resistance | 400 K/W - quantifies self-heating under 30 mA DC drive; requires ≥16 mm² copper pad for rated power dissipation |
Pinout & Package
Package: PLCC-2 (SMD, low-profile, white thermoplastic body with embedded lead frame and clear epoxy reflector cavity; dimensions: 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 mm; recommended footprint per Vishay drawing 6.541-5067.01-4).

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLME3100-GS08 | Same die, identical optical/electrical specs, but shipped in 7500-piece GS08 tape (5 × 1500); no brightness/wavelength binning differences | Identical use cases; differs only in packaging quantity and reel configuration | Select VLME3100-GS08 when smaller reel size or legacy procurement alignment is required |
| OSRAM LYT676 | Yellow AlInGaP LED with comparable 585–595 nm dominant wavelength and ±60° viewing angle; luminous intensity 30–80 mcd at 10 mA | Same automotive and indicator applications; validated in OSRAM's AEC-Q101-compliant portfolio | Choose LYT676 for dual-sourcing flexibility where Vishay second-source validation is needed |
Compared with VLME3101-GS18, VLME3100-GS08 offers identical performance in a smaller reel format, while LYT676 provides cross-manufacturer functional equivalence with minor intensity and wavelength tolerance shifts-both require no PCB redesign but differ in tape/reel logistics and qualification documentation lineage.

FAQ
What is the maximum forward current rating for VLME3101-GS18?
The absolute maximum DC forward current for VLME3101-GS18 is 30 mA at ambient temperatures ≤85 °C. Exceeding this value risks accelerated degradation and reduced lifetime. For continuous operation, Vishay recommends limiting average current to 20 mA to maintain luminous output stability and thermal margin, especially in enclosed or high-temperature environments where junction temperature must stay below +125 °C. The VLME3101-GS18 datasheet specifies VF = 2.0–2.6 V at 20 mA, supporting robust resistor-based or constant-current driver designs.
Is VLME3101-GS18 compatible with lead-free reflow soldering processes?
Yes, VLME3101-GS18 is fully compatible with Pb-free IR reflow soldering per J-STD-020C Class 3, supporting peak package body temperatures up to 260 °C for ≤100 seconds. Its construction meets CECC 00802 and JEDEC level 2a preconditioning requirements, ensuring moisture sensitivity is managed without mandatory baking if sealed bags are opened and used within 672 hours at <30 °C/60 % RH. The VLME3101-GS18's thermal resistance (RthJA = 400 K/W) also allows safe thermal cycling when mounted on ≥16 mm² copper pads.
What does the "GS18" suffix indicate in VLME3101-GS18?
The "GS18" suffix in VLME3101-GS18 denotes Vishay's preferred tape-and-reel packaging option: 8000 pieces per reel, using an antistatic 8 mm blister tape compliant with DIN IEC 40 (CO 564). This differs from GS08 (7500 pieces, 5 × 1500) and reflects optimized logistics for high-volume SMT lines. The GS18 reel dimensions are standardized per Figure 12 in the VLME3101-GS18 datasheet, and the label includes barcodes for traceability, batch codes, and environmental compliance (RoHS, halogen-free). The VLME3101-GS18 device itself is unchanged-only packaging differs.
How is luminous intensity binned for VLME3101-GS18?
Luminous intensity for VLME3101-GS18 is binned into six groups (N–S), each with defined min/max mcd ranges (e.g., Group N: 28.0–35.5 mcd; Group S: 180–280 mcd), measured at 10 mA pulse conditions. Each GS18 reel contains only one intensity group-no mixing-and IVmax/IVmin ≤ 1.6 within that group. Wavelength is similarly binned into six 3 nm bands (581–594 nm). This binning ensures predictable brightness and color matching across production lots, critical for VLME3101-GS18 applications like automotive dashboards where visual consistency matters.
Does VLME3101-GS18 require special ESD handling?
Yes, VLME3101-GS18 is an electrostatic-sensitive device (ESD class 1B per ANSI/ESDA/JEDEC JS-001), requiring handling in EPA environments with grounded workstations, wrist straps, and antistatic packaging. The device ships in moisture-barrier aluminum bags labeled with EIA JEDEC JESD22-A112 level 2a and ESD warning symbols. Once opened, exposure to ambient humidity above 60 % RH for >672 hours necessitates baking before reflow. Proper ESD control prevents latent damage to the AlInGaP junction, preserving the VLME3101-GS18's forward voltage stability and luminous output over its operational lifetime.
