Product details
Overview
VLMG31L1M2-GS18 from Vishay Semiconductors is a green surface-mount LED in PLCC-2 package, featuring luminous intensity of 11.2–28 mcd at 10 mA, dominant wavelength 562–575 nm, forward voltage 2.1–2.8 V at 20 mA, ±60° viewing angle, and GaP-on-GaP chip technology - used for indicator and backlighting in office equipment and LCD panels.
For engineers reviewing the VLMG31L1M2-GS18 datasheet, VLMG31L1M2-GS18 pinout, VLMG31L1M2-GS18 application, or VLMG31L1M2-GS18 equivalent, key selection criteria include luminous intensity binning (L1/M2 group), thermal resistance (400 K/W), ESD rating (2 kV), IR reflow compatibility, and non-diffused lens suitability for light-pipe coupling.
Technical Context
This green LED uses GaP-on-GaP semiconductor technology with a clear epoxy lens and white thermoplastic reflector, enabling high brightness and consistent color output. Its PLCC-2 package supports automated placement and withstands JEDEC level 2a preconditioning and J-STD-020-compliant reflow profiles up to 260 °C.
Optical performance is defined by dominant wavelength (562–575 nm), ±60° half-intensity angle, and luminous intensity ratio ≤1.6 within a reel. Electrical behavior includes 20 mA DC forward current rating, 6 V reverse voltage limit, and junction-to-ambient thermal resistance of 400 K/W on ≥16 mm² PCB pad.

Equivalent & Alternatives
The following parts are listed as comparable options for similar green LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LGT670-L1M2 | OSRAM-branded equivalent with identical optical/electrical specs and PLCC-2 footprint | No functional difference; same binning, wavelength, and intensity ranges as VLMG31L1M2-GS18 | Select LGT670-L1M2 when dual-sourcing from OSRAM is required for supply chain diversification |
| VLMG31L1M2-GS08 | Same luminous intensity and wavelength specs but supplied in 1500-piece GS08 tape instead of 8000-piece GS18 reel | Lower quantity per reel increases changeover frequency in high-volume SMT lines | Choose VLMG31L1M2-GS08 only for prototyping or low-volume production where reel size flexibility is prioritized |
Compared with LGT670-L1M2 and VLMG31L1M2-GS08, the VLMG31L1M2-GS18 offers identical photometric performance and mechanical compatibility while optimizing for high-volume manufacturing via its 8000-piece tape format and JEDEC level 2a moisture sensitivity rating.

FAQ
What is the luminous intensity range of the VLMG31L1M2-GS18 at 10 mA?
The VLMG31L1M2-GS18 has a luminous intensity range of 11.2–28 mcd at 10 mA, corresponding to the L1/M2 binning group per Vishay's classification table. This range ensures predictable brightness for visual indicators while allowing controlled variation within a single reel. The VLMG31L1M2-GS18 maintains this specification under standard test conditions of 25 ms pulse width and ±11% measurement accuracy.
Does the VLMG31L1M2-GS18 require baking before reflow soldering?
No, the VLMG31L1M2-GS18 is preconditioned to JEDEC level 2a and shipped in dry-packed anti-humidity bags, permitting direct reflow without baking if mounted within 672 hours of bag opening under ≤30 °C/60% RH conditions. The VLMG31L1M2-GS18 complies with J-STD-020 peak temperature limits up to 260 °C, making it suitable for standard lead-free reflow profiles.
What is the dominant wavelength specification for the VLMG31L1M2-GS18?
The dominant wavelength of the VLMG31L1M2-GS18 is specified as 562–575 nm at 10 mA, placing it in the medium-green spectrum. This range aligns with Vishay's color binning group 8 (572–575 nm) and ensures consistent visual appearance across production lots. The VLMG31L1M2-GS18 achieves this using GaP-on-GaP chip technology, which provides stable wavelength output over temperature and lifetime.
Is the VLMG31L1M2-GS18 compatible with automatic pick-and-place equipment?
Yes, the VLMG31L1M2-GS18 is fully compatible with standard SMT placement systems due to its PLCC-2 package geometry, EIA-compliant tape format (GS18, 8 mm blister tape), and mechanical robustness. The VLMG31L1M2-GS18's 3.5 mm × 2.8 mm footprint and 1.75 mm height meet industry-standard vision alignment and vacuum nozzle requirements for high-speed placement.
What is the maximum DC forward current rating for the VLMG31L1M2-GS18?
The VLMG31L1M2-GS18 has a maximum DC forward current rating of 20 mA at ambient temperatures ≤74 °C. Exceeding this current risks accelerated degradation and thermal runaway due to its 56 mW power dissipation limit and 400 K/W junction-to-ambient thermal resistance. The VLMG31L1M2-GS18 must be driven with appropriate current-limiting circuitry to maintain reliability over its rated lifetime.
