Product details
Overview
VLMR31R2T1-34-GS08 from Vishay Semiconductors is an orange-red AlInGaP-on-GaAs surface-mount LED in PLCC-2 package, delivering 280–355 mcd luminous intensity at 20 mA, with dominant wavelength 612–624 nm and ±60° viewing angle-designed for automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLMR31R2T1-34-GS08 datasheet, VLMR31R2T1-34-GS08 pinout, VLMR31R2T1-34-GS08 application, or VLMR31R2T1-34-GS08 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, JEDEC level 2a preconditioning, ESD rating (2 kV), and tape-and-reel packaging details (GS08 = 1500 pcs/reel).
Technical Context
The VLMR31R2T1-34-GS08 uses AlInGaP-on-GaAs die technology to achieve high-brightness orange-red emission with tight binning: luminous intensity group T (280–355 mcd) and color group 4 (620–624 nm dominant wavelength). Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and non-diffused optics optimized for light-pipe coupling.
It operates at IF = 20 mA with VF = 1.8–2.4 V, supports IR reflow per J-STD-020, and maintains thermal resistance RthJA = 400 K/W when mounted on ≥16 mm² PCB pad. Absolute maximum ratings include IF = 30 mA DC, VR = 5 V, and TJ = 125 °C.

Is the VLMR31R2T1-34-GS08 qualified for automotive use?
Yes, the VLMR31R2T1-34-GS08 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, humidity exposure, and mechanical shock-making it suitable for instrument cluster backlighting, switch illumination, and other under-dash automotive applications.
What does the "-34" suffix indicate in VLMR31R2T1-34-GS08?
The "-34" suffix in VLMR31R2T1-34-GS08 denotes the specific luminous intensity and color bin: "R2" indicates intensity group R (112–180 mcd) and color group 2 (612–616 nm), but per Vishay documentation, the full part number VLMR31R2T1-34-GS08 maps to intensity group T (280–355 mcd) and color group 4 (620–624 nm), confirming its high-brightness orange-red specification.
Can the VLMR31R2T1-34-GS08 be used with standard lead-free reflow processes?
Yes, the VLMR31R2T1-34-GS08 is fully compatible with lead-free IR reflow per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 s. Its PLCC-2 package is also qualified for vapor-phase and wave soldering per CECC 00802, ensuring robustness in high-throughput SMT lines.
What is the maximum forward current rating for continuous operation of the VLMR31R2T1-34-GS08?
The VLMR31R2T1-34-GS08 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤85 °C. Operating at its typical test current of 20 mA delivers optimal luminous output and thermal stability, with junction temperature limited to 125 °C under recommended PCB pad conditions (≥16 mm²).
