Product details
Overview
VLMW41S1T2-7K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN blue die with TAG phosphor conversion, delivering 180–450 mcd luminous intensity at 10 mA, ±60° viewing angle, and chromaticity coordinates (x=0.33, y=0.33) per CIE 1931, designed for automotive signal lighting and indicator applications.
For engineers reviewing the VLMW41S1T2-7K8L-08 datasheet, VLMW41S1T2-7K8L-08 pinout, VLMW41S1T2-7K8L-08 application, or VLMW41S1T2-7K8L-08 equivalent, key selection criteria include luminous intensity binning (T2 group), 7K chromaticity grade, PLCC-2 package compatibility with reflow soldering, and AEC-Q101 qualification for automotive use.
Technical Context
This device employs a blue InGaN LED chip on sapphire substrate, optically coupled to a TAG phosphor-epoxy mixture inside a white thermoplastic PLCC-2 reflector cavity, enabling white light generation via partial blue-to-yellow wavelength conversion. Its thermal resistance junction-to-ambient is 360 K/W when mounted on a PCB pad >16 mm².
The VLMW41S1T2-7K8L-08 operates within -40 °C to +100 °C ambient temperature range, supports DC forward current up to 20 mA (with 100 ms surge limit), and exhibits forward voltage of 3.3–4.2 V at 20 mA, with temperature coefficients of -3 mV/K for VF and -0.4 %/K for IV.

FAQ
What is the luminous intensity range of the VLMW41S1T2-7K8L-08 at 10 mA?
The VLMW41S1T2-7K8L-08 delivers a luminous intensity of 180–450 mcd at 10 mA, corresponding to the T2 brightness bin per Vishay's classification table. This range reflects factory-tested variation within a single reel and supports consistent visual output in multi-LED arrays when binned appropriately. The VLMW41S1T2-7K8L-08 is specified with this tolerance to ensure manufacturability while meeting automotive photometric requirements.
Is the VLMW41S1T2-7K8L-08 qualified for automotive applications?
Yes, the VLMW41S1T2-7K8L-08 is AEC-Q101 qualified, confirming its suitability for automotive lighting applications including brake lights, turn signals, side markers, and interior indicators. This qualification covers stress tests for temperature cycling, humidity, mechanical shock, and ESD - all validated per the AEC standard. The VLMW41S1T2-7K8L-08 meets these requirements as a discrete white LED emitter in its PLCC-2 package.
What does the "7K" in VLMW41S1T2-7K8L-08 signify?
The "7K" denotes the chromaticity coordinate bin per Vishay's white LED classification: x = 0.330, y = 0.330 (CIE 1931), falling within the 7K group defined in the datasheet's chromaticity coordinate table. This ensures consistent white point across production lots and enables color-matching in multi-LED assemblies. The VLMW41S1T2-7K8L-08 uses this precise binning to meet automotive and industrial visual consistency requirements.
Can the VLMW41S1T2-7K8L-08 be soldered using standard reflow profiles?
Yes, the VLMW41S1T2-7K8L-08 is compatible with Pb-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤100 s. Its PLCC-2 package is rated for vapor-phase and wave soldering per CECC 00802. Preconditioning to JEDEC Level 2a ensures safe processing - the VLMW41S1T2-7K8L-08 must be mounted within 672 hours of bag opening or baked if exposed to ambient conditions exceeding storage limits.
What is the maximum DC forward current rating for the VLMW41S1T2-7K8L-08?
The absolute maximum DC forward current for the VLMW41S1T2-7K8L-08 is 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated lumen depreciation and junction overheating, especially given its thermal resistance of 360 K/W. For reliable long-term operation in automotive environments, Vishay recommends operating at ≤20 mA with appropriate thermal pad design - the VLMW41S1T2-7K8L-08 is not rated for reverse operation or surge currents beyond 100 ms.
