Product details
Overview
VLMG31K1M2-GS08 from Vishay Semiconductors is a surface-mount green LED in PLCC-2 package, with dominant wavelength 572 nm, luminous intensity 15–28 mcd at 10 mA, forward voltage 2.1–2.8 V at 20 mA, and ±60° viewing angle - designed for indicator and backlighting applications in office and telecom equipment.
For engineers reviewing the VLMG31K1M2-GS08 datasheet, VLMG31K1M2-GS08 pinout, VLMG31K1M2-GS08 application, or VLMG31K1M2-GS08 equivalent, this part delivers standardized SMD LED performance with JEDEC level 2a preconditioning, 2 kV ESD rating, and compatibility with IR reflow, vapor phase, and wave soldering per J-STD-020 and CECC 00802.
Technical Context
This green GaP-on-GaP LED operates at 10 mA test current for optical characterization, with peak wavelength at 565 nm and dominant wavelength binned to 572 nm (Group 8). Its non-diffused lens enables efficient coupling to light pipes and flat backlighting structures.
The device features thermal resistance junction-to-ambient of 400 K/W when mounted on a PCB pad >16 mm², supports ambient operation from –40 °C to +100 °C, and maintains luminous intensity ratio IVmax/IVmin ≤ 1.6 within a single tape reel - ensuring consistent brightness across production units.

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-K1M2 | OSRAM cross-reference; identical luminous intensity (15–28 mcd), same dominant wavelength (572 nm), PLCC-2 package | No functional difference - validated drop-in replacement per Vishay's crossing table | Select LGT670-K1M2 when dual-sourcing from OSRAM-authorized channels is required |
| VLMG31L1M2-GS08 | Same package and wavelength, but higher min. luminous intensity (11.2 mcd vs. 7.1 mcd) and tighter binning (L-group vs. K-group) | Better suited for applications demanding higher baseline brightness consistency across batches | Choose VLMG31L1M2-GS08 where minimum visibility threshold exceeds 11 mcd under low-ambient conditions |
Compared with VLMG31K1M2-GS08, LGT670-K1M2 offers identical photometric and mechanical specs for seamless second-source flexibility, while VLMG31L1M2-GS08 trades wider intensity tolerance for guaranteed higher minimum output - enabling design margin in dimly lit environments.

FAQ
What is the maximum forward current rating for VLMG31K1M2-GS08?
The absolute maximum DC forward current for VLMG31K1M2-GS08 is 20 mA at ambient temperatures ≤74 °C. Exceeding this value risks accelerated degradation or thermal runaway. The device supports surge currents up to 340 mA for pulses ≤10 μs, but continuous operation must remain within the 20 mA limit to maintain rated lifetime and luminous output stability. VLMG31K1M2-GS08 must be used with appropriate current-limiting circuitry.
Does VLMG31K1M2-GS08 require baking before reflow soldering?
No - VLMG31K1M2-GS08 is preconditioned to JEDEC level 2a and shipped in dry-packed anti-humidity reels. It may be mounted directly within 672 hours of opening the bag under ≤30 °C / 60 % RH conditions without baking. If exposure exceeds this window or humidity indicator cards show >10 % RH, baking at 60 °C for 96 hours under <5 % RH is required. VLMG31K1M2-GS08 complies with J-STD-020 moisture sensitivity protocols.
What does the "GS08" suffix indicate in VLMG31K1M2-GS08?
The "GS08" suffix denotes Vishay's standard 8 mm antistatic blister tape packaging option containing 1500 pieces per reel. This format is optimized for compatibility with automated pick-and-place machines and conforms to DIN IEC 40 (CO) 564. GS08 differs from GS18 (8000 pcs/reel) in tape width, cavity pitch, and reel dimensions - VLMG31K1M2-GS08 must be specified with GS08 when 1500-unit reels are required for production line feeders.
Is VLMG31K1M2-GS08 compatible with lead-free reflow processes?
Yes - VLMG31K1M2-GS08 is qualified for Pb-free reflow soldering per J-STD-020, with a peak package body temperature limit of 260 °C for ≤10 seconds. Its construction supports ramp rates up to 3 °C/s (up) and 6 °C/s (down), and it withstands the full profile including preheat, soak, reflow, and cooling phases. VLMG31K1M2-GS08 has been verified for compatibility with common SAC305 and SN100C solder alloys.
How is luminous intensity binned for VLMG31K1M2-GS08?
VLMG31K1M2-GS08 is binned into the "K1M2" group: K = luminous intensity range (7.1–9 mcd for K1, 9–11.2 mcd for K2), M = upper intensity tier (18–22.4 mcd for M1, 22.4–28 mcd for M2), and "2" indicates wavelength Group 8 (572–575 nm). Each GS08 reel contains only one K/M/wavelength combination - VLMG31K1M2-GS08 guarantees no mixing of brightness or color bins within a single reel.
