Product details
Overview
VLMP3101-GS18 from Vishay Semiconductors is a surface-mount green LED in PLCC-2 package, emitting at dominant wavelength 562–575 nm with typical luminous intensity of 16 mcd at 10 mA, forward voltage 2.1 V (typ.) at 20 mA, and ±60° viewing angle - used for LCD backlighting, indicator panels, and office equipment status lighting.
For engineers reviewing the VLMP3101-GS18 datasheet, VLMP3101-GS18 pinout, VLMP3101-GS18 application, or VLMP3101-GS18 equivalent, this page delivers verified optical, electrical, thermal, and packaging data - including JEDEC level 2a preconditioning compliance, 8 mm tape packaging (GS18 = 8000 pcs/reel), and RoHS-compliant lead-free construction.
Technical Context
This green LED uses GaP-on-GaP semiconductor technology, delivering stable chromaticity within the 562–575 nm dominant wavelength range and peak emission near 565 nm. Its non-diffused lens enables efficient coupling to light pipes and uniform flat backlighting across LCDs and membrane switches.
The device operates at DC forward current up to 20 mA (Tamb ≤ 74 °C), with thermal resistance junction-to-ambient of 400 K/W when mounted on ≥16 mm² PCB pad. It supports infrared, vapor-phase, and wave soldering per CECC 00802 and J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4.5–16 mcd min–max at 10 mA; enables consistent brightness grading within bin J2 per Vishay's intensity classification table |
| Dominant wavelength | 562–575 nm; ensures standardized green color output suitable for visual status indication and human-factor-compliant displays |
| Forward voltage | 2.1 V (typ.) at 20 mA; allows low-power drive with standard 3.3 V or 5 V logic-level current-limiting resistor networks |
| Viewing angle | ±60° half-intensity; provides wide, uniform illumination ideal for front-panel indicators and edge-lit backlight zones |
| Absolute max current | 20 mA DC (Tamb ≤ 74 °C); defines safe continuous operating limit without derating for industrial ambient conditions |
| Junction temperature | 100 °C max; sets thermal design boundary for PCB copper area, airflow, and adjacent heat sources in sealed enclosures |
| Reverse voltage | 6 V max; permits basic reverse-polarity protection using series diode or bidirectional TVS in low-voltage systems |
Pinout & Package
PLCC-2 package: 2-pin surface-mount lead frame embedded in white thermoplastic housing with clear epoxy lens; dimensions 3.5 × 2.8 mm (L × W), height 1.75 mm, with 2.2 mm center-to-center pin spacing and 0.9 mm pin width. Mounting pad layout requires 2.6 mm × 1.6 mm solder pads with soldermask-defined areas.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source or microcontroller GPIO via current-limiting resistor; polarity must be observed during placement |
| Cathode (K) | Ground/negative terminal | Typically tied to system ground; reverse connection blocks conduction and risks damage if voltage exceeds 6 V |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables precise optical coupling to light guides and backlights without scattering loss - critical for high-efficiency LCD edge-lighting |
| Luminous intensity ratio ≤ 1.6 | Ensures tight brightness matching within one reel (J2 bin), eliminating manual sorting for uniform panel illumination |
| EIA/ICE standard PLCC-2 | Guarantees compatibility with automated pick-and-place machines and standard SMT reflow profiles (J-STD-020, level 2a) |
| Low profile (1.75 mm height) | Supports ultra-thin device designs such as portable medical interfaces and slim industrial HMI bezels |
| JEDEC level 2a preconditioning | Validates moisture sensitivity for lead-free reflow; eliminates need for baking unless exposed >672 h at >30°C/60% RH |

Use Value: 4.5–16 mcd intensity range allows calibrated brightness matching across multi-color symbol sets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar green LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMG3100-GS18 | Same PLCC-2 package, identical 562–575 nm dominant wavelength, but lower luminous intensity (4.5–16 mcd vs. VLMP3101-GS18's 4.5–16 mcd - same binning; actual typ. value 16 mcd matches) | No functional difference; both rated for LCD backlighting and indicator use per Vishay documentation | Select VLMG3100-GS18 only if sourcing legacy part numbers; VLMP3101-GS18 is current production variant with identical specs |
| VLMG3102-GS08 | Higher intensity grade (11.2–18 mcd), same wavelength and package, but supplied in GS08 tape (1500 pcs/reel) instead of GS18 (8000 pcs/reel) | Better suited for high-brightness applications like outdoor-facing status lights where >11 mcd is required | Choose VLMG3102-GS08 when higher luminance is needed and smaller reel quantity is acceptable; not drop-in for volume production requiring 8000-unit reels |
Compared with VLMP3101-GS18, VLMG3100-GS18 offers identical optical and electrical performance in identical packaging and reel format, while VLMG3102-GS08 trades reel size for higher intensity - making VLMP3101-GS18 optimal for cost-sensitive, high-volume backlighting where J2-bin consistency and 8000-unit reels reduce assembly line changeovers.

FAQ
What is the dominant wavelength range of the VLMP3101-GS18?
The VLMP3101-GS18 has a dominant wavelength range of 562–575 nm, measured at 10 mA forward current. This places it firmly in the green spectral band and aligns with Vishay's VLMG310. series specification. The peak wavelength is 565 nm, confirming its narrow-band green emission suitable for color-critical indicator applications.
Is the VLMP3101-GS18 compatible with lead-free reflow soldering?
Yes, the VLMP3101-GS18 is fully compatible with lead-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 s. It is preconditioned to JEDEC level 2a and shipped in dry-packed anti-humidity bags with EIA JESD22-A112 labeling - enabling direct placement without baking if used within 672 hours of bag opening.
What does the "GS18" suffix mean in VLMP3101-GS18?
The "GS18" suffix indicates an 8 mm carrier tape format containing 8000 units per reel - Vishay's preferred high-volume packaging option. This contrasts with "GS08", which holds 1500 units. Both use antistatic blister tape compliant with DIN IEC 40 (CO) 564 and support automatic placement equipment.
Does the VLMP3101-GS18 have a diffused or non-diffused lens?
The VLMP3101-GS18 features a non-diffused lens, as confirmed in the Vishay datasheet under FEATURES: "Non-diffused lens: excellent for coupling to light pipes and backlighting." This optical design preserves beam collimation and maximizes coupling efficiency into light guides - essential for uniform LCD backlighting.
What is the maximum DC forward current rating for VLMP3101-GS18?
The absolute maximum DC forward current for VLMP3101-GS18 is 20 mA at ambient temperatures ≤74 °C. Exceeding this value risks accelerated degradation or thermal runaway. At higher ambient temperatures, current must be derated per Figure 1 in the datasheet - e.g., to ~12 mA at 100 °C ambient.
