Product details
Overview
VLMW33U2AA-5K8L-08 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, delivering 560–1400 mcd luminous intensity at 20 mA, with forward voltage 3.7–4.2 V and chromaticity coordinates (x=0.33, y=0.33) per CIE 1931, designed for automotive dashboard backlighting and industrial indicator applications.
For engineers reviewing the VLMW33U2AA-5K8L-08 datasheet, VLMW33U2AA-5K8L-08 pinout, VLMW33U2AA-5K8L-08 application, or VLMW33U2AA-5K8L-08 equivalent, key selection criteria include luminous intensity binning (U2AA 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 (U2AA = 560–1400 mcd) and chromaticity (5K8L = x/y = 0.33/0.33), ensuring consistent color rendering 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.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 560–1400 mcd at 20 mA - defines brightness binning for consistent visual output in multi-LED arrays |
| Forward Voltage | 3.7–4.2 V at 20 mA - determines driver voltage headroom and power dissipation (max 127 mW) |
| Chromaticity Coordinates | x = 0.33, y = 0.33 per CIE 1931 - ensures standardized cool-white color point for UI consistency |
| Viewing Angle | ±60° half-intensity - provides wide, uniform illumination suitable for panel indicators and symbol backlighting |
| ESD Withstand | 1 kV HBM per JESD22-A114-B - enables robust handling in automated assembly without special ESD controls |
| Thermal Resistance | 400 K/W (junction-to-ambient) - requires ≥16 mm² copper pad for thermal management at full rated current |
| AEC-Q101 Qualified | Qualified for automotive electronics - validates reliability under temperature cycling, humidity, and mechanical stress |
Pinout & Package
Package: PLCC-2 surface-mount package with white thermoplastic body, integrated reflector cavity filled with epoxy/TAG phosphor mix, and lead frame embedded for thermal and electrical conduction. Dimensions: 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 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 |
|---|---|---|
| Anode (A) | Positive DC input | Connected to driver's high-side output; polarity must be observed to avoid reverse breakdown (max VR = 5 V) |
| Cathode (K) | Ground return path | Low-impedance connection to PCB ground plane; critical for thermal dissipation and EMI control |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/TAG-on-SiC technology | Enables high luminous efficacy and stable color over lifetime vs. conventional YAG phosphor LEDs |
| Luminous intensity binning (U2AA) | Guarantees 560–1400 mcd output per reel - eliminates post-production sorting for brightness-matched assemblies |
| Chromaticity binning (5K8L) | Ensures precise (x,y) = (0.33,0.33) white point - critical for multi-LED displays requiring uniform color appearance |
| AEC-Q101 qualification | Validates suitability for automotive interior lighting including dashboards, switches, and HVAC controls |
| IR-reflow compatible | Withstands peak reflow temperatures up to 260 °C per J-STD-020 - supports standard Pb-free SMT processes |
Applications
| Automotive Dashboard Backlighting | Office Equipment Indicator Panels |
|---|---|
Use Scenario: Illuminating segmented symbols and analog gauge markings in vehicle instrument clusters under varying ambient light conditions. IC Role / Device Role / Timing Role: Discrete white light source driven by constant-current LED driver ICs (e.g., ASL3410, MAX16803). Use Value: AEC-Q101 qualification and ±60° viewing angle ensure reliable, glare-free visibility across driver's field of view without secondary optics. | Use Scenario: Providing status indication on multifunction printers, scanners, and copiers with high ambient light rejection. IC Role / Device Role / Timing Role: Standalone indicator LED powered from 3.3 V or 5 V rail via current-limiting resistor or low-dropout regulator. Use Value: U2AA luminous intensity binning guarantees consistent brightness across production batches, eliminating manual calibration. |
| Telecom Device Keypad Backlighting | Industrial Control Panel Symbols |
Use Scenario: Edge-lit alphanumeric keys on VoIP phones and fax machines requiring low-power, long-life illumination. IC Role / Device Role / Timing Role: Low-current (20 mA) white emitter paired with microcontroller GPIO or dedicated LED driver (e.g., TLC59116). Use Value: 3.7–4.2 V forward voltage aligns with standard logic-level supply rails; 1 kV ESD rating prevents damage during board handling. | Use Scenario: Highlighting function labels and safety icons on PLC operator interfaces exposed to vibration and temperature extremes. IC Role / Device Role / Timing Role: Ruggedized discrete LED selected for extended operational life (>50,000 h) and thermal stability in unventilated enclosures. Use Value: –40 to +100 °C operating range and 110 °C max junction temperature support deployment in harsh industrial environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LWT67C-U2AA | Same luminous intensity bin (U2AA), identical chromaticity (0.33/0.33), but PLCC-2 footprint differs slightly in leadframe geometry and thermal pad layout | Requires PCB footprint revision due to 0.1 mm pad centerline offset and different thermal pad dimensions | Select only if redesigning layout; not drop-in compatible despite matching optical specs |
| Vishay VLMW33U2AA-5K8L-18 | Identical optical/electrical specs, same binning, but supplied in 8000-piece GS18 tape (vs. 1500-piece GS08 for -08 variant) | Optimized for high-volume automated placement; same performance and reliability, differing only in packaging quantity and reel dimensions | Choose -18 for production runs >50k units; -08 preferred for prototyping and low-volume builds |
Compared with VLMW33U2AA-5K8L-08, OSRAM LWT67C-U2AA demands PCB layout changes despite matching photometric specs, while VLMW33U2AA-5K8L-18 offers identical performance in higher-reel packaging-making it a volume-scaling alternative rather than a functional substitute.

FAQ
What is the luminous intensity range of the VLMW33U2AA-5K8L-08 at 20 mA?
The VLMW33U2AA-5K8L-08 delivers a minimum luminous intensity of 560 mcd, typical value of 650 mcd, and maximum of 1400 mcd at 20 mA forward current. This U2AA binning ensures predictable brightness for design validation and batch-to-batch consistency in production assemblies using the VLMW33U2AA-5K8L-08.
Is the VLMW33U2AA-5K8L-08 qualified for automotive applications?
Yes, the VLMW33U2AA-5K8L-08 is AEC-Q101 qualified, confirming its reliability under automotive-grade stress tests including temperature cycling, humidity exposure, and mechanical shock. This makes the VLMW33U2AA-5K8L-08 suitable for non-safety-critical interior lighting such as dashboard symbols and switch backlighting.
What is the maximum forward current rating for continuous operation of the VLMW33U2AA-5K8L-08?
The VLMW33U2AA-5K8L-08 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤ 70 °C. Exceeding this current or operating above 70 °C ambient without thermal derating risks exceeding the 110 °C maximum junction temperature and accelerated lumen depreciation in the VLMW33U2AA-5K8L-08.
Does the VLMW33U2AA-5K8L-08 require baking before reflow soldering?
Yes - the VLMW33U2AA-5K8L-08 is moisture-sensitive per JEDEC level 2a and must be baked if exposed to ambient conditions >672 hours after opening the dry bag. Recommended bake: 96 hours at 60 °C ± 5 °C and <5 % RH, or 192 hours at 40 °C ± 5 °C and <5 % RH, prior to reflow processing of the VLMW33U2AA-5K8L-08.
What does the "5K8L" suffix indicate in the VLMW33U2AA-5K8L-08 part number?
The "5K8L" suffix in VLMW33U2AA-5K8L-08 specifies the chromaticity bin: "5K" denotes x = 0.296, y = 0.259 base coordinates, and "8L" selects the final calibrated bin with x = 0.345, y = 0.352 - resulting in the actual measured (0.33, 0.33) point per CIE 1931 used in the VLMW33U2AA-5K8L-08.
