Product details
Overview
VLMW41S1T2-5K5L-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=0.291, y=268) per CIE 1931 for cool white light in automotive marker and interior lighting applications.
For engineers reviewing the VLMW41S1T2-5K5L-08 datasheet, VLMW41S1T2-5K5L-08 pinout, VLMW41S1T2-5K5L-08 application, or VLMW41S1T2-5K5L-08 equivalent, key selection criteria include luminous intensity binning (S1T2 group), chromaticity grade (5K5L), PLCC-2 package compatibility with reflow soldering, and AEC-Q101 qualification for automotive use.
Technical Context
This device employs a blue InGaN LED chip mounted on sapphire substrate, optically coupled to a TAG phosphor-epoxy mixture inside a white thermoplastic PLCC-2 reflector cavity; the resulting spectral output combines unconverted blue emission with phosphor-converted yellow to achieve white light with correlated color temperature near 5500 K.
It operates at forward current up to 20 mA with 3.3–4.2 V typical forward voltage at 20 mA, exhibits -3 mV/K temperature coefficient of VF, and -0.4 %/K temperature coefficient of luminous intensity; thermal resistance junction-to-ambient is 360 K/W when mounted on ≥16 mm² PCB copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 180–450 mcd at 10 mA - defines brightness binning for consistent optical output across production reels |
| Chromaticity Coordinates | x = 0.291, y = 0.268 (CIE 1931) - specifies precise cool white point within 5K5L bin group |
| Viewing Angle | ±60° half-intensity - determines beam spread for uniform illumination in indicator and marker applications |
| Forward Voltage | 3.3–4.2 V at 20 mA - sets minimum driver compliance voltage and power dissipation (max 84 mW) |
| Junction Temperature | 110 °C max - constrains thermal design margin when operating at full 20 mA in enclosed automotive environments |
| ESD Withstand | 2 kV HBM (JESD22-A114-B) - informs ESD handling requirements during SMT assembly and board handling |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - enables use in brake lights, turn signals, and side markers without additional qualification |
Pinout & Package
Package: PLCC-2 (Plastic Leaded Chip Carrier, 2-terminal), 3.5 mm × 1.75 mm body, 2.8 mm lead pitch, with anode (A) and cathode (C) terminals identified per Vishay mechanical drawing. Mounting pad layout requires ≥16 mm² copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input | Must be driven at ≥3.3 V above cathode to forward-bias InGaN junction; polarity-sensitive - reverse operation not permitted |
| Cathode (C) | Ground return path | Connected to PCB ground plane; serves as thermal and electrical reference; no internal protection diode |
Key Features
| Feature | Design Value |
|---|---|
| InGaN + TAG phosphor architecture | Enables stable cool white emission (5500 K) with high luminous efficacy and low chromaticity shift over life |
| AEC-Q101 qualification | Confirms suitability for automotive exterior lighting including brake lights and side markers without derating |
| PLCC-2 package with white reflector | Maximizes light extraction efficiency and provides mechanical robustness for automated SMT placement |
| JEDEC level 2a preconditioning | Ensures moisture sensitivity compliance for lead-free reflow (peak 260 °C) without baking prior to assembly |
| EIA/ICE standard footprint | Guarantees compatibility with industry-standard pick-and-place equipment and stencil designs |
Applications
| Automotive Side Marker Lights | Interior Dashboard Backlighting |
|---|---|
Use Scenario: Mounted in molded plastic housings along vehicle fenders to meet FMVSS 108 visibility requirements at ±60° horizontal field. IC Role / Device Role / Timing Role: Light-emitting element providing regulated white illumination under 10–20 mA constant-current drive.

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LWT67C-5K5L | OSRAM PLCC-2 white LED with identical 5K5L chromaticity bin and ±60° viewing angle; VF 3.0–4.0 V at 20 mA | Slightly lower forward voltage reduces driver power loss; same AEC-Q101 qualification and JEDEC level 2a moisture sensitivity | Select when optimizing for lower thermal load in high-density LED arrays |
| VLMW41S1T2-7K8L-08 | Same Vishay family, identical PLCC-2 package and InGaN/TAG technology, but 7K8L chromaticity bin (x=0.330, y=0.330) and higher 450 mcd max intensity | Warmer white point (≈6500 K) and higher output suit applications needing greater luminance or different CCT grading | Select when matching adjacent LEDs in multi-source lighting systems requiring tighter chromaticity grouping |
Compared with VLMW41S1T2-5K5L-08, LWT67C-5K5L offers marginally lower VF for reduced thermal stress, while VLMW41S1T2-7K8L-08 provides higher intensity and warmer white light - both require separate optical validation due to non-identical chromaticity and intensity bins.

FAQ
What is the chromaticity specification for VLMW41S1T2-5K5L-08?
The VLMW41S1T2-5K5L-08 is binned to the 5K5L chromaticity group per CIE 1931, with confirmed coordinates x = 0.291 and y = 0.268 at 10 mA forward current. This corresponds to a cool white light with approximate correlated color temperature of 5500 K, and is verified per Vishay Document Number 81370 Rev. 2.1.
Is VLMW41S1T2-5K5L-08 suitable for automotive exterior lighting applications?
Yes, VLMW41S1T2-5K5L-08 is AEC-Q101 qualified and rated for operating temperatures from –40 °C to +100 °C, making it suitable for automotive exterior lighting such as side markers and brake lights. Its PLCC-2 package, 2 kV ESD rating, and moisture sensitivity level 2a further support robust deployment in automotive production environments.
What is the maximum forward current rating for VLMW41S1T2-5K5L-08?
The absolute maximum DC forward current for VLMW41S1T2-5K5L-08 is 20 mA at ambient temperatures ≤ 80 °C. Exceeding this limit risks accelerated lumen depreciation and junction temperature exceeding the 110 °C maximum, especially without adequate PCB copper area (≥16 mm² recommended).
Does VLMW41S1T2-5K5L-08 have built-in reverse polarity protection?
No, VLMW41S1T2-5K5L-08 does not include internal protection circuitry. The datasheet explicitly states "Not designed for reverse operation", and applying reverse voltage may cause permanent damage. External series protection diodes or careful PCB layout are required in bidirectional or miswiring-prone applications.
What tape-and-reel option is used for VLMW41S1T2-5K5L-08?
VLMW41S1T2-5K5L-08 ships in antistatic 8 mm blister tape per DIN IEC 40 (CO) 564, with 1500 pieces per reel (tape code -08). The reel conforms to GS08 dimensions and includes JESD22-A112 level 2a labeling for moisture sensitivity - no baking is required if assembled within 672 hours of bag opening under ≤60 % RH conditions.
