Product details
Overview
VLMW41R1T1-5K8L-18 from Vishay Semiconductors is a white surface-mount LED using InGaN/TAG-on-sapphire technology, delivering 112–355 mcd luminous intensity at 10 mA, with CIE 1931 chromaticity coordinates (x=0.33, y=0.33), ±60° viewing angle, and forward voltage of 3.3–4.2 V at 20 mA - deployed in automotive marker lights and interior indicator applications.
For engineers reviewing the VLMW41R1T1-5K8L-18 datasheet, VLMW41R1T1-5K8L-18 pinout, VLMW41R1T1-5K8L-18 application, or VLMW41R1T1-5K8L-18 equivalent, key selection criteria include luminous intensity binning (R-group: 112–140 mcd), AEC-Q101 qualification, PLCC-2 package thermal resistance (360 K/W), and JEDEC level 2a moisture sensitivity handling.
Technical Context
This device uses blue InGaN die with TAG phosphor conversion to produce white light, achieving typical color temperature of 5500 K and chromaticity tightly binned per CIE 1931 (5K8L denotes x=0.330/y=0.310 and x=0.352/y=0.344). It operates within -40 °C to +100 °C ambient range and supports reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802.
The PLCC-2 package features a white thermoplastic body with embedded lead frame and epoxy/phosphor-filled reflector. Thermal resistance junction-to-ambient is 360 K/W when mounted on ≥16 mm² PCB pad, and ESD withstand voltage reaches 2 kV (HBM, JESD22-A114-B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 112–355 mcd at 10 mA - defines brightness range for R-group binning used in consistent visual signaling |
| Forward Voltage | 3.3–4.2 V at 20 mA - determines minimum driver headroom and power dissipation (max 84 mW) |
| Chromaticity Coordinates | x = 0.330, y = 0.310 and x = 0.352, y = 0.344 (5K8L group) - ensures color consistency across production reels |
| Viewing Angle | ±60° - enables wide-angle illumination suitable for panel indicators and side-marker lighting |
| Junction Temperature | Max 110 °C - sets thermal derating limit for continuous operation at rated current |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - required for under-hood and exterior lighting modules |
| Moisture Sensitivity Level | JESD22-A112 Level 2a - mandates baking or dry-box storage after tape opening to prevent popcorning during reflow |
Pinout & Package
Package: PLCC-2 (Plastic Leaded Chip Carrier, 2-terminal), 3.5 mm × 1.75 mm footprint, 0.9 mm height, with cathode marked by chamfered corner and anode identified by larger pad area. Mounting pad layout follows Vishay-recommended 2.8 mm × 1.6 mm copper land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input | Connected to constant-current source; requires series resistor or regulated driver for 10–20 mA operation |
| Cathode (C) | Ground return path | Internally connected to lead frame; must be soldered to thermal pad for optimal heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/TAG-on-sapphire die | Enables stable white emission with low thermal drift (TCIV = −0.4 %/K) and high efficiency vs. AlInGaP alternatives |
| AEC-Q101 qualification | Confirms suitability for automotive exterior lighting including brake, turn, and side-marker functions without additional qualification effort |
| PLCC-2 package with white thermoplastic body | Provides >90% reflectivity in compact SMD form factor, supporting high-lumen density in space-constrained designs |
| JEDEC Level 2a preconditioning | Ensures robustness against moisture-induced failure during Pb-free reflow (peak 260 °C), reducing field return risk |
| Chromacity binning per CIE 1931 | Guarantees color-matching across reels - critical for multi-LED arrays in branding or status indication |
Applications
| Automotive Side Markers | Dashboard Indicator Lights |
|---|---|
Use Scenario: Mounted on vehicle fenders to meet FMVSS 108 visibility requirements at ±60° horizontal plane. IC Role / Device Role / Timing Role: Light-emitting component driven by constant-current automotive LED controller (e.g., ASL3410).

Use Value: R-group luminous intensity binning (112–140 mcd) ensures consistent perceived brightness across production batches and operating temperatures. |
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-5K8L | OSRAM equivalent; identical 5K8L chromaticity bin, same PLCC-2 package, but higher max luminous intensity (450 mcd) | Preferred where higher brightness margin is needed for outdoor-readable panels | Select LWT67C-5K8L if system-level optical design requires >355 mcd headroom |
| VLMW41S1T1-5K8L-18 | Same Vishay family; S-group binning (180–280 mcd) - 68 mcd higher min intensity than VLMW41R1T1-5K8L-18 | Better suited for applications needing tighter brightness consistency above 180 mcd threshold | Choose VLMW41S1T1-5K8L-18 when luminous intensity >180 mcd is mandatory for visual detection distance |
Compared with LWT67C-5K8L and VLMW41S1T1-5K8L-18, the VLMW41R1T1-5K8L-18 offers lower minimum intensity (112 mcd) ideal for cost-sensitive interior indicators, while retaining identical chromaticity, thermal performance, and AEC-Q101 qualification - enabling drop-in substitution where brightness tolerance allows.

FAQ
What is the luminous intensity range of the VLMW41R1T1-5K8L-18?
The VLMW41R1T1-5K8L-18 has a luminous intensity range of 112–355 mcd at 10 mA, corresponding to the R-group binning (112–140 mcd minimum). This range is measured with ±11% accuracy using a 25 ms current pulse, and each reel ships with only one brightness group - no mixing across bins occurs.
Is the VLMW41R1T1-5K8L-18 qualified for automotive use?
Yes, the VLMW41R1T1-5K8L-18 is AEC-Q101 qualified, confirming its reliability for automotive applications including brake lights, turn signals, side markers, and interior lighting. Its construction - InGaN/TAG-on-sapphire die, PLCC-2 package, and JEDEC level 2a moisture handling - meets stringent automotive environmental and lifetime requirements.
What does the "5K8L" suffix mean in VLMW41R1T1-5K8L-18?
The "5K8L" suffix identifies the chromaticity bin per Vishay's white LED classification: it specifies two coordinate pairs - (x=0.330, y=0.310) and (x=0.352, y=0.344) - both falling within the 5500 K correlated color temperature range. This ensures consistent white appearance across production lots and enables color-matched multi-LED assemblies.
Can the VLMW41R1T1-5K8L-18 be used in reflow soldering processes?
Yes, the VLMW41R1T1-5K8L-18 is compatible with Pb-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. It is preconditioned to JEDEC level 2a and supplied in antistatic 8 mm tape (GS18 option: 8000 pcs/reel), with recommended ramp rates of ≤3 °C/s (up) and ≤6 °C/s (down).
What is the maximum forward current rating for the VLMW41R1T1-5K8L-18?
The absolute maximum DC forward current for the VLMW41R1T1-5K8L-18 is 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated degradation; for continuous operation at full rating, thermal management must maintain junction temperature ≤110 °C - achievable with ≥16 mm² PCB copper area per the datasheet's RthJA = 360 K/W specification.
