Product details
Overview
VLMO3101-GS08 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 - optimized for indicator and backlighting applications in office equipment and audio/video interfaces.
For engineers reviewing the VLMO3101-GS08 datasheet, VLMO3101-GS08 pinout, VLMO3101-GS08 application, or VLMO3101-GS08 equivalent, this device requires attention to forward voltage (2.0–2.8 V @ 20 mA), thermal resistance (400 K/W), luminous intensity binning (J-group), and JEDEC Level 2a moisture sensitivity handling prior to reflow.
Technical Context
The VLMO3101-GS08 uses GaAsP-on-GaP semiconductor technology to achieve soft orange emission with tight dominant wavelength control (598–611 nm) and low forward voltage (2.0–2.8 V). Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and non-diffused optics for efficient light coupling.
Designed for automated SMT assembly, it supports infrared, vapor-phase, and wave soldering per CECC 00802 and J-STD-020, and ships in 8 mm tape (GS08 = 1500 pcs/reel). Luminous intensity ratio within one reel is ≤1.6 (IVmax/IVmin), ensuring consistent brightness across production units.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4.5–10 mcd @ 10 mA - defines visible brightness level for human-readable indicators under standard drive conditions |
| Dominant wavelength | 598–611 nm - specifies soft orange chromaticity suitable for high-visibility status indication without glare |
| Forward voltage | 2.0–2.8 V @ 20 mA - determines minimum supply headroom and series resistor sizing in constant-current drive circuits |
| Viewing angle | ±60° - enables wide-angle illumination for panel-mounted indicators and uniform backlighting of symbols/switches |
| Absolute max forward current | 20 mA @ Tamb ≤ 74 °C - sets continuous DC operating limit; exceeds this requires pulse derating per Fig. 23 |
| Junction-to-ambient thermal resistance | 400 K/W on >16 mm² PCB pad - informs thermal design margin for sustained operation at elevated ambient temperatures |
| Moisture sensitivity level | JEDEC Level 2a - mandates baking or dry-box storage if sealed bag opened >672 h before reflow soldering |
Pinout & Package
VLMO3101-GS08 uses a 2-pin PLCC-2 surface-mount package with molded white thermoplastic body and clear epoxy lens. Dimensions: 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 mm height; pin pitch 2.2 mm; cathode identified by chamfered corner per Vishay drawing 6.541-5067.01-4.

| Cathode (K) | Negative terminal | Marked by chamfered corner; connects to ground or current sink; reverse leakage ≤10 μA at 6 V |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables precise optical coupling to light pipes and edge-lit LCD backlights without scattering loss |
| Luminous intensity binning | J-group (4.5–7.1 mcd) ensures predictable brightness matching across LEDs in multi-indicator panels |
| SMD PLCC-2 footprint | Standard EIA/ICE-compliant package compatible with automated pick-and-place and reflow processes |
| Low power consumption | 20 mA max rating at 2.8 V enables battery-powered or energy-sensitive designs with minimal thermal load |
| Wide operating temperature | -40 to +100 °C ambient range supports deployment in industrial control panels and automotive cabin interfaces |
Applications
| Office Equipment Indicator | Audio/Video Backlight |
|---|---|
Use Scenario: Status indication on multifunction printers, scanners, and copiers with user-facing control panels. IC Role / Device Role / Timing Role: Discrete visual indicator providing real-time operational feedback (e.g., ready, error, paper jam). Use Value: Soft orange color offers high contrast against gray/black plastic housings while minimizing eye fatigue during prolonged exposure. |
Use Scenario: Backlighting of front-panel buttons and display segments in AV receivers and home theater systems. IC Role / Device Role / Timing Role: Constant-current driven light source synchronized with system power-on sequence. Use Value: ±60° viewing angle ensures uniform illumination across button arrays without hotspots or dark zones. |
| Telecom Device Indicator | LCD Symbol Backlight |
Use Scenario: Power and line-status indicators on VoIP phones and fax machines with compact PCB layouts. IC Role / Device Role / Timing Role: Low-profile SMD LED integrated into dense front-end assemblies with minimal Z-height impact. Use Value: PLCC-2 package allows placement adjacent to connectors and displays without interfering with mechanical enclosures. |
Use Scenario: Edge-lit backlight for segmented LCDs in test equipment, instrumentation, and industrial HMI displays. IC Role / Device Role / Timing Role: Primary light source coupled via light guide to distribute illumination evenly behind transparent symbols. Use Value: Non-diffused lens maximizes coupling efficiency into acrylic light pipes, reducing required drive current and heat generation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMY3101-GS08 | Yellow emission (581–594 nm), slightly higher typical luminous intensity (10 mcd vs. 8 mcd), VF 2.1–2.8 V | Better chromatic separation from red/green indicators; used where color-coding requires distinct yellow identity | Select when color differentiation is critical and soft orange is insufficient for visual coding standards |
| VLMO3100-GS08 | Same soft orange spectrum but lower luminous intensity (2.8–8 mcd); J-group binning not applicable (only F/G/H groups) | Suitable for low-brightness indicator roles where reduced visibility is acceptable or preferred | Choose for cost-sensitive designs where full J-group brightness is unnecessary and tighter binning adds no value |
Compared with VLMO3100-GS08, VLMO3101-GS08 provides higher and more tightly binned luminous intensity for consistent panel appearance, while VLMO3101-GS08 differs from VLMY3101-GS08 primarily in dominant wavelength - enabling selective use in multi-color indicator systems without spectral overlap.

FAQ
What is the dominant wavelength range of VLMO3101-GS08?
The dominant wavelength of VLMO3101-GS08 is specified as 598–611 nm, placing its emission firmly in the soft orange region. This range is measured at 10 mA forward current and ensures consistent color rendering across production lots. The peak wavelength is 605 nm, confirming spectral alignment with industry-standard orange indicators. This specification is validated per Vishay Document 84789 Rev. 2.6.
What is the maximum continuous forward current for VLMO3101-GS08?
VLMO3101-GS08 has a maximum DC forward current rating of 20 mA at ambient temperatures ≤ 74 °C. Exceeding this value risks accelerated degradation or thermal runaway. At higher ambient temperatures, derating is required per Figure 1 in the Vishay datasheet - e.g., ~15 mA at 85 °C. Pulse operation up to 340 mA is permitted for ≤10 μs pulses, as defined in the Absolute Maximum Ratings table.
How is luminous intensity binned for VLMO3101-GS08?
VLMO3101-GS08 is binned into the J-group per Vishay's luminous intensity classification, covering 4.5–7.1 mcd at 10 mA. Each reel contains only one brightness group, with IVmax/IVmin ≤ 1.6 within the unit. This ensures uniform appearance in multi-LED applications like status panels. The "1" suffix in VLMO3101-GS08 explicitly denotes J-group intensity, distinguishing it from VLMO3100 (H-group) and VLMO3102 (K-group).
What soldering profiles are recommended for VLMO3101-GS08?
Vishay specifies lead-free reflow soldering per J-STD-020, with peak temperature ≤ 260 °C for ≤ 10 s, time above 217 °C limited to 30–120 s, and ramp rates ≤ 3 °C/s (up) and ≤ 6 °C/s (down). Wave soldering is also supported per CECC 00802. Preconditioning to JEDEC Level 2a is mandatory; unsealed reels must be baked (e.g., 96 h at 60 °C/<5% RH) if exposed >672 h before reflow.
Does VLMO3101-GS08 have a diffused or non-diffused lens?
VLMO3101-GS08 features a non-diffused lens, as confirmed in the Features section of Vishay Document 84789: "Non-diffused lens: excellent for coupling to light pipes and backlighting." This optical design preserves beam collimation and maximizes coupling efficiency into light guides or edge-lit LCD assemblies - unlike diffused variants that scatter light for wider viewing at the expense of intensity.
