Product details
Overview
VLMG31K1L2-GS08 from Vishay Semiconductors is a green surface-mount LED in PLCC-2 package, featuring dominant wavelength 572 nm, luminous intensity 7.1–18 mcd at 10 mA, forward voltage 2.1–2.8 V at 20 mA, ±60° viewing angle, and GaP-on-GaP semiconductor technology - used for indicator and backlighting in telecommunication and office equipment.
For engineers reviewing the VLMG31K1L2-GS08 datasheet, VLMG31K1L2-GS08 pinout, VLMG31K1L2-GS08 application, or VLMG31K1L2-GS08 equivalent, this part supports IR reflow soldering per J-STD-020, meets JEDEC level 2a preconditioning, and delivers consistent brightness binning (IVmax/IVmin ≤ 1.6) within each tape reel.
Technical Context
This green LED uses GaP-on-GaP epitaxial structure to achieve narrow dominant wavelength range (562–575 nm) with peak at 565 nm, enabling high color consistency in multi-LED arrays. Its non-diffused lens provides directional light output optimized for coupling into light pipes and LCD backlighting.
The PLCC-2 package features white thermoplastic body with internal reflector and clear epoxy lens, supporting thermal resistance of 400 K/W when mounted on ≥16 mm² PCB pad. It operates across –40 °C to +100 °C ambient temperature and withstands 2 kV ESD per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Green - precise chromaticity for status indication and symbol illumination |
| Dominant wavelength | 562–575 nm (typ. 572 nm) - ensures visual consistency across production batches |
| Luminous intensity | 7.1–18 mcd at 10 mA - categorized in L-group (11.2–18.0 mcd), enabling predictable brightness matching |
| Forward voltage | 2.1–2.8 V at 20 mA - compatible with standard 3.3 V or 5 V logic-level current-limiting drive circuits |
| Viewing angle | ±60° - balances wide visibility with sufficient directionality for localized backlighting |
| ESD withstand | 2 kV HBM - reduces handling sensitivity during SMT assembly and board handling |
| Junction-to-ambient Rth | 400 K/W on ≥16 mm² pad - defines maximum continuous power dissipation (56 mW) under thermal design constraints |
Pinout & Package
PLCC-2 package: 2-pin surface-mount device with cathode (pin 1) and anode (pin 2) terminals; molded white thermoplastic body with integrated reflector and clear epoxy lens; overall dimensions 3.5 mm × 2.8 mm × 2.2 mm (L × W × H); recommended footprint includes 2.6 mm × 1.6 mm solder pads with soldermask-defined areas.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to ground or current-sink driver; polarity must be observed to avoid reverse-bias damage beyond 6 V |
| Pin 2 | Anode | Connected to positive supply via current-limiting resistor or constant-current source; enables standard low-side switching |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar green LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LGT670-K1L2 | OSRAM equivalent; identical optical specs (562–575 nm, 7.1–18 mcd), same PLCC-2 package and pinout | No functional difference; validated drop-in replacement per Vishay cross-reference table | Select LGT670-K1L2 when dual-sourcing from OSRAM is required for supply chain resilience |
| VLMG31K1M2-GS08 | Same family, higher luminous intensity bin (7.1–28 mcd vs. 7.1–18 mcd); otherwise identical electrical/optical specs | Suitable where higher brightness is needed without changing layout or drive circuitry | Choose VLMG31K1M2-GS08 only if design requires >18 mcd minimum intensity at 10 mA |
Compared with VLMG31K1L2-GS08, LGT670-K1L2 offers identical performance and mechanical fit with alternate sourcing, while VLMG31K1M2-GS08 provides higher intensity headroom within the same footprint and drive conditions - neither requires PCB redesign.

FAQ
What is the maximum continuous forward current rating for VLMG31K1L2-GS08?
The absolute maximum DC forward current for VLMG31K1L2-GS08 is 20 mA at ambient temperatures ≤74 °C. Exceeding this value risks accelerated lumen depreciation and junction overheating. The device is characterized at 10 mA for luminous intensity and 20 mA for forward voltage, making 10–15 mA the recommended operating range for long-term reliability.
Does VLMG31K1L2-GS08 require baking before reflow soldering?
VLMG31K1L2-GS08 is shipped in moisture-barrier packaging with JEDEC level 2a labeling and does not require baking if mounted within 672 hours of opening the dry bag under ≤30 °C/60 % RH conditions. Baking (e.g., 96 h at 60 °C/<5 % RH) is only necessary if humidity indicator cards show >10 % RH exposure or time limits are exceeded.
What is the meaning of "GS08" in VLMG31K1L2-GS08?
"GS08" denotes Vishay's standard 8 mm antistatic blister tape packaging containing 1500 units per reel. This format is optimized for high-speed pick-and-place machines and complies with DIN IEC 40 (CO) 564. The "GS" prefix indicates tape-and-reel delivery, while "08" specifies the 8 mm tape width and associated reel dimensions.
Can VLMG31K1L2-GS08 be used in reverse-bias configurations?
VLMG31K1L2-GS08 has a reverse voltage rating of 6 V and is rated for short-term reverse conduction per datasheet Note (1). However, it is not designed for sustained reverse operation - use only in standard forward-biased LED configurations with appropriate current limiting. Reverse bias beyond 6 V risks permanent junction degradation.
How is luminous intensity binned for VLMG31K1L2-GS08?
VLMG31K1L2-GS08 is binned into the "L" group (11.2–18.0 mcd at 10 mA), with no mixing of intensity groups on a single reel. Each reel contains only one brightness subgroup (L1 or L2), ensuring IVmax/IVmin ≤ 1.6 within that unit - critical for uniform appearance in multi-LED panels without post-assembly sorting.
