Product details
Overview
VLMW33T2U2-5K8L-18 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, designed for automotive dashboard backlighting and office equipment indicators. It delivers 560–1400 mcd luminous intensity at 20 mA, with forward voltage 3.7–4.2 V, chromaticity coordinates (x=0.33, y=0.33), and ±60° viewing angle.
For engineers reviewing the VLMW33T2U2-5K8L-18 datasheet, VLMW33T2U2-5K8L-18 pinout, VLMW33T2U2-5K8L-18 application, or VLMW33T2U2-5K8L-18 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, JEDEC level 2a moisture sensitivity, and tape-and-reel packaging details (8000 pcs/reel, GS18 option).
Technical Context
This InGaN/TAG-on-SiC white LED uses phosphor-converted blue emission to achieve CIE 1931 chromaticity (x=0.33, y=0.33) and typical 5500 K color temperature. Its PLCC-2 thermoplastic package integrates a reflective epoxy-TAG phosphor cavity and lead frame structure optimized for thermal dissipation.
Rated for 30 mA DC forward current and 110 °C junction temperature, it features -0.5 %/K luminous intensity temperature coefficient and -4 mV/K forward voltage coefficient. ESD withstand voltage reaches 1 kV (JESD22-A114-B), and it supports IR reflow, vapor phase, and wave soldering per J-STD-020 and CECC 00802.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 560–1400 mcd at 20 mA - defines brightness range for indicator visibility under ambient lighting |
| Forward Voltage | 3.7–4.2 V at 20 mA - determines driver voltage headroom and power loss in series configurations |
| Chromaticity Coordinates | x = 0.33, y = 0.33 (CIE 1931) - ensures consistent white point across production batches |
| Viewing Angle | ±60° - enables wide-angle illumination suitable for panel-level backlighting |
| Junction Temperature | 110 °C max - sets thermal design limit for PCB pad area (>16 mm²) and ambient operating range |
| Thermal Resistance | 400 K/W (junction-to-ambient, mounted on ≥16 mm² pad) - quantifies thermal path efficiency for reliability modeling |
| ESD Withstand | 1 kV (HBM, JESD22-A114-B) - indicates handling robustness during assembly without special grounding |
Pinout & Package
Package: PLCC-2 surface-mount package with 2-pin configuration, white thermoplastic body, integrated reflector cavity, and lead frame substrate. 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 |

Applications
| Automotive Dashboard Backlighting | Office Equipment Indicators |
|---|---|
Use Scenario: Illuminating segmented symbols and icons on instrument cluster overlays under varying cabin lighting conditions. IC Role / Device Role / Timing Role: Light source providing uniform, high-visibility white illumination with stable color point over temperature. Use Value: Meets AEC-Q101 requirements for automotive environments and maintains CIE (0.33, 0.33) chromaticity across -40 to +100 °C operating range. |
Use Scenario: Status indication on printers, scanners, and multifunction devices where consistent brightness and white point are critical for user recognition. IC Role / Device Role / Timing Role: Discrete visible-light emitter driven at 20 mA for low-power, long-life indicator function. Use Value: Delivers 560–1400 mcd output with ±60° viewing angle to ensure visibility from multiple angles without hotspots. |
| Telecom Device Backlighting | LCD Symbol Illumination |
Use Scenario: Backlighting keypads and display borders in telephones and fax machines requiring low-profile, surface-mount light sources. IC Role / Device Role / Timing Role: Primary white illumination element mounted directly on PCB adjacent to translucent overlays. Use Value: PLCC-2 package enables compact layout; 3.7–4.2 V VF simplifies integration with 3.3 V or 5 V supply rails via single-series resistor. |
Use Scenario: Edge-lit or direct-lit symbols on control panels, switches, and industrial HMI interfaces needing flat, diffuse white light. IC Role / Device Role / Timing Role: High-brightness discrete LED replacing incandescent lamps in space-constrained applications. Use Value: 110 °C max junction temperature and 400 K/W RthJA support continuous operation in enclosed enclosures without active cooling. |
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-18 | Identical luminous intensity range (560–1400 mcd), same chromaticity (x=0.33, y=0.33), identical package and ratings | No functional difference; differs only in internal binning label (U2AA vs. T2U2) - both fall within same brightness group U and chromaticity group 8L | Select based on inventory availability; electrically and mechanically interchangeable |
| OSRAM LWT67C-U2AA | Same PLCC-2 package, 570–1420 mcd at 20 mA, x=0.33/y=0.33, but higher VF range (3.8–4.4 V) and no AEC-Q101 qualification | Suitable for industrial/commercial use but not automotive; requires higher driver voltage margin | Choose for non-automotive designs where AEC-Q101 is not required and slightly higher VF is acceptable |
Compared with VLMW33T2U2-5K8L-18, VLMW33U2AA-5K8L-18 offers identical performance and qualification, while OSRAM LWT67C-U2AA provides similar optical output but lacks automotive qualification and has higher forward voltage tolerance - making it appropriate only for commercial-grade systems.

FAQ
What is the maximum forward current rating for VLMW33T2U2-5K8L-18?
The absolute maximum DC forward current for VLMW33T2U2-5K8L-18 is 30 mA at ambient temperatures ≤70 °C. Exceeding this value risks accelerated lumen depreciation and potential junction failure. The device is typically operated at 20 mA to balance brightness, efficiency, and lifetime - as specified in its optical/electrical characteristics table.
Is VLMW33T2U2-5K8L-18 qualified for automotive applications?
Yes, VLMW33T2U2-5K8L-18 is AEC-Q101 qualified, meaning it has passed stress tests for automotive-grade reliability including temperature cycling, high-temperature operating life, and mechanical shock. This qualification supports its use in dashboard backlighting and switch illumination per ISO/TS 16949-compliant manufacturing processes.
What does the "5K8L" suffix in VLMW33T2U2-5K8L-18 indicate?
The "5K8L" suffix identifies chromaticity binning: "8L" specifies CIE 1931 coordinates x=0.33/y=0.33 (tightest white point tolerance), while "5K" denotes a secondary chromaticity group used for internal traceability. This ensures consistent color matching across reels shipped to the same customer.
What is the moisture sensitivity level (MSL) of VLMW33T2U2-5K8L-18?
VLMW33T2U2-5K8L-18 is rated at JEDEC J-STD-020 Level 2a, with a floor life of 672 hours (28 days) at ≤30 °C and ≤60 % RH after dry pack opening. If exposed beyond this window, baking per J-STD-033 is required before reflow - e.g., 96 h at 60 °C and <5 % RH - to prevent popcorning during soldering.
Can VLMW33T2U2-5K8L-18 be used in reverse-bias configurations?
VLMW33T2U2-5K8L-18 permits short-term reverse bias up to 5 V (per absolute maximum ratings), but it is not designed for sustained reverse conduction. Reverse operation may cause gradual degradation; the device should be used strictly in forward-biased mode for reliable long-term performance in applications like VLMW33T2U2-5K8L-18 indicator circuits.
