Product details
Overview
VLMW33T2AA-5K8L-08 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, delivering 1120–1400 mcd luminous intensity at 20 mA, with forward voltage 3.7–4.2 V and CIE 1931 chromaticity coordinates (x=0.33, y=0.33), designed for automotive dashboard backlighting and LCD symbol illumination.
For engineers reviewing the VLMW33T2AA-5K8L-08 datasheet, VLMW33T2AA-5K8L-08 pinout, VLMW33T2AA-5K8L-08 application, or VLMW33T2AA-5K8L-08 equivalent, key selection criteria include luminous intensity binning (AA group), ±60° viewing angle, AEC-Q101 qualification, and compatibility with IR-reflow soldering per J-STD-020.
Technical Context
This device uses InGaN blue die with TAG phosphor on SiC substrate to generate white light via partial blue-to-yellow wavelength conversion. Its optical output is binned by luminous intensity (AA group: 1120–1400 mcd) and chromaticity (5K8L bin: x=0.330, y=0.330 per CIE 1931), ensuring consistent color point across production reels.
Thermally, it features 400 K/W junction-to-ambient thermal resistance when mounted on ≥16 mm² PCB pad, supports continuous DC forward current up to 30 mA at Tamb ≤ 70 °C, and operates across -40 to +100 °C ambient range with 110 °C max junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW33U2AA-5K8L-08 | Luminous intensity range 560–1400 mcd (U group), same chromaticity bin and package | Lower minimum intensity may require higher drive current or tighter bin control for uniformity-critical panels | Select when lower-cost intensity tier suffices and tighter AA-group consistency is not required |
| OSRAM LWT67C-U2AA | Same PLCC-2 package, 570–1400 mcd (U group), chromaticity x/y = 0.33/0.33, but no AEC-Q101 claim | Not automotive-qualified; suitable for industrial/commercial but not safety-critical automotive interiors | Choose for non-automotive applications where cost or local sourcing drives preference |
Compared with VLMW33T2AA-5K8L-08, the U2AA variant offers broader intensity tolerance and lower cost, while the OSRAM alternative matches optical specs but lacks AEC-Q101 validation-making VLMW33T2AA-5K8L-08 the only option when automotive qualification and tight AA-bin consistency are mandatory.

FAQ
What is the luminous intensity range of the VLMW33T2AA-5K8L-08?
The VLMW33T2AA-5K8L-08 has a luminous intensity range of 1120–1400 mcd at 20 mA forward current, corresponding to the AA brightness bin per Vishay's classification table. This range ensures high visibility for indicator and backlighting functions while maintaining consistency across production reels shipped with identical binning.
Is the VLMW33T2AA-5K8L-08 qualified for automotive applications?
Yes, the VLMW33T2AA-5K8L-08 is AEC-Q101 qualified, confirming its reliability for automotive interior lighting applications including dashboard backlighting and switch illumination. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD, making VLMW33T2AA-5K8L-08 suitable for deployment in vehicles without additional qualification effort.
What is the chromaticity coordinate specification for the VLMW33T2AA-5K8L-08?
The VLMW33T2AA-5K8L-08 is binned to the 5K8L chromaticity group, with confirmed CIE 1931 coordinates of x = 0.330 and y = 0.330. This precise binning ensures consistent warm-white color point across all units on a given reel, eliminating visible color variation in multi-LED assemblies such as control panels or message boards.
What is the maximum forward current rating for the VLMW33T2AA-5K8L-08?
The absolute maximum DC forward current for the VLMW33T2AA-5K8L-08 is 30 mA at ambient temperatures ≤ 70 °C. At higher ambient temperatures, derating is required per the datasheet's forward current vs. ambient temperature curve. Operating at the rated 20 mA ensures optimal lumen maintenance and thermal stability over lifetime.
Does the VLMW33T2AA-5K8L-08 require baking before reflow soldering?
No, the VLMW33T2AA-5K8L-08 is preconditioned to JEDEC Level 2a and shipped in dry-packed antistatic reels, allowing direct placement into standard Pb-free reflow profiles (peak 260 °C, ≤120 s) without prior baking-provided the sealed bag is opened and used within 672 hours at ≤30 °C/60 % RH. Extended exposure requires baking per JESD22-A112 guidelines.
