Product details
Overview
VLMC3100-GS18 from Vishay Semiconductors is a green surface-mount LED in PLCC-2 package, rated for 2 mA forward current, with dominant wavelength 572 nm, forward voltage 1.9–2.4 V, and luminous intensity 0.71–2.0 mcd. It serves as a low-power indicator or backlight in compact consumer and industrial electronics.
For engineers reviewing the VLMC3100-GS18 datasheet, VLMC3100-GS18 pinout, VLMC3100-GS18 application, or VLMC3100-GS18 equivalent, key selection criteria include its ±60° viewing angle, GaP-on-GaP semiconductor technology, JEDEC level 2a moisture sensitivity, 8 mm tape packaging (GS18 = 8000 pcs/reel), and compatibility with IR reflow soldering per J-STD-020.
Technical Context
The VLMC3100-GS18 is a low-current, non-diffused SMD LED optimized for optical coupling to light pipes and flat backlighting. Its PLCC-2 package features a white thermoplastic body with embedded lead frame and clear epoxy lens, enabling high brightness at 2 mA drive current.
Optical performance is characterized at 25 ms pulse width with ±11% measurement accuracy. The device operates across -40 °C to +100 °C ambient temperature, with thermal resistance junction-to-ambient of 500 K/W when mounted on ≥16 mm² PCB pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 0.71–2.0 mcd at 2 mA - defines visible output level for indicator readability under typical ambient lighting |
| Dominant wavelength | 562–575 nm - specifies green spectral output suitable for human-eye-optimized signaling |
| Forward voltage | 1.9–2.4 V at 2 mA - determines minimum supply headroom and series resistor sizing |
| Viewing angle | ±60° - sets beam spread for uniform illumination across small panels or symbols |
| Absolute max forward current | 7 mA at Tamb ≤ 90 °C - establishes safe continuous drive limit without thermal derating |
| Junction-to-ambient Rth | 500 K/W - quantifies thermal path efficiency for board-level thermal management |
| Moisture sensitivity level | JEDEC level 2a - mandates dry-pack handling and ≤672 h factory floor exposure before reflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMC3100-GS08 | Same die, identical optical/electrical specs, but supplied in 1500-piece GS08 tape (vs. 8000-piece GS18) | Lower reel quantity suits low-volume prototyping or short-run production | Select GS08 when smaller lot sizes reduce inventory risk or match small-batch assembly schedules |
| VLMC3101-GS18 | Higher luminous intensity bin (1.12–2.0 mcd vs. 0.71–2.0 mcd), otherwise identical package, wavelength, and voltage | Brighter output better suited for higher ambient light environments or longer light-pipe paths | Choose VLMC3101-GS18 when enhanced visibility is required without changing layout or drive circuitry |
Compared with VLMC3100-GS18, VLMC3100-GS08 offers identical performance in a smaller reel size for flexibility, while VLMC3101-GS18 provides higher luminance within the same footprint and drive conditions-enabling brightness scaling without redesign.

FAQ
What is the maximum continuous forward current rating for VLMC3100-GS18?
The VLMC3100-GS18 has a DC forward current rating of 7 mA at ambient temperatures ≤ 90 °C. Exceeding this value risks accelerated degradation or thermal runaway. For reliable long-term operation, Vishay recommends driving VLMC3100-GS18 at its specified test condition of 2 mA, where luminous intensity and forward voltage are characterized.
Does VLMC3100-GS18 require baking before reflow soldering?
VLMC3100-GS18 is packaged per JEDEC level 2a moisture sensitivity and must be baked if exposed to ambient conditions >672 hours after opening the dry bag. Baking at 60 °C ± 5 °C for 96 hours at <5 % RH restores moisture compliance. The VLMC3100-GS18 reel includes an EIA JEDEC JESD22-A112 level 2a label confirming this requirement.
What is the dominant wavelength range of VLMC3100-GS18 and why does it matter?
The dominant wavelength of VLMC3100-GS18 is 562–575 nm, placing its green emission in the peak photopic sensitivity region of the human eye. This ensures high perceived brightness at low drive currents and supports consistent color coding in multi-LED interfaces. Wavelength binning is controlled per Vishay's Group 8 classification (572–575 nm).
Can VLMC3100-GS18 be used in outdoor applications?
Yes, VLMC3100-GS18 is rated for operation from -40 °C to +100 °C ambient temperature and features a white thermoplastic PLCC-2 package resistant to UV-induced yellowing. Its ±60° viewing angle and non-diffused lens maintain directional output in variable lighting, making VLMC3100-GS18 suitable for outdoor kiosk indicators and industrial control panels.
What tape option does VLMC3100-GS18 use and how many units are per reel?
VLMC3100-GS18 uses the GS18 taping option, delivering 8000 units per reel in antistatic 8 mm blister tape compliant with DIN IEC 40 (CO) 564. This high-density packaging supports high-throughput SMT placement and reduces reel change frequency compared to the GS08 option (1500 units/reel).
