Product details
Overview
VLMW41S1T2-6K6L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN/TAG-on-sapphire technology, delivering 180–450 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 backlighting.
For engineers reviewing the VLMW41S1T2-6K6L-08 datasheet, VLMW41S1T2-6K6L-08 pinout, VLMW41S1T2-6K6L-08 application, or VLMW41S1T2-6K6L-08 equivalent, key selection criteria include luminous intensity binning (T2 group), chromaticity group (6K6L), AEC-Q101 qualification, PLCC-2 package compatibility with reflow soldering, and thermal resistance of 360 K/W.
Technical Context
This device uses blue InGaN die with TAG phosphor conversion to produce white light, achieving correlated color temperature ~5500 K. Its PLCC-2 package features a white thermoplastic body with integrated reflector cavity filled with epoxy-phosphor mixture.
Optical performance is defined by ±60° half-intensity angle and CIE 1931 chromaticity coordinates tightly binned to (0.33, 0.33) per packing unit. It operates within -40 °C to +100 °C ambient range, with junction temperature limited to 110 °C and ESD withstand voltage rated at 2 kV (HBM, JESD22-A114-B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 180–450 mcd at 10 mA - defines brightness level for indicator visibility under standard drive conditions |
| Chromaticity Coordinates | (x = 0.33, y = 0.33) per CIE 1931 - ensures consistent white point across production reels |
| Forward Voltage | 3.3–4.2 V at 20 mA - determines minimum supply headroom and series resistor sizing |
| Viewing Angle | ±60° - specifies angular distribution for uniform illumination in panel or symbol applications |
| Thermal Resistance | 360 K/W (junction-to-ambient, mounted on >16 mm² pad) - sets maximum power dissipation limit at given board layout |
| ESD Withstand | 2 kV HBM (JESD22-A114-B) - informs ESD protection requirements in handling and PCB design |
| 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 footprint, with cathode (C) and anode (A) terminals identified per Vishay mechanical drawing. Mounting pad layout requires soldermask-defined 2.8 mm × 1.6 mm pads with 0.8 mm center-to-center spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input | Connected to current-limiting resistor or constant-current driver output; polarity must be observed to avoid reverse breakdown |
| Cathode (C) | Ground reference | Common return path; internal connection to lead frame; must be tied to system ground or driver low-side switch |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/TAG-on-sapphire die | Enables high-efficiency white emission with stable 5500 K CCT and minimal spectral shift over life |
| AEC-Q101 qualification | Confirms suitability for automotive lighting systems including brake, turn, and marker functions without derating |
| PLCC-2 package with white thermoplastic body | Provides high reflectivity (>90%) and thermal stability up to 110 °C junction temperature |
| JEDEC Level 2a preconditioning | Ensures moisture sensitivity compliance for Pb-free reflow (peak 260 °C) without baking prior to assembly |
| EIA/ICE standard footprint | Guarantees compatibility with automated pick-and-place and standard SMT reflow profiles (J-STD-020) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW41S1T2-7K8L-08 | Same PLCC-2 package and InGaN/TAG die, but chromaticity group 7K8L (x=0.33, y=0.33 → x=0.345, y=0.352); higher max luminous intensity (450 mcd vs. 450 mcd - identical upper bound) | Suitable where tighter warm-white tolerance is required; not interchangeable without optical recalibration | Select when matching adjacent LEDs with 7K8L binning or targeting higher-yield assemblies with looser chromaticity spec |
| OSRAM LWT67C-6K6L | PLCC-2 white LED with comparable 5500 K CCT and ±60° viewing angle; different phosphor formulation yields minor spectral divergence; JEDEC Level 2a compliant but not AEC-Q101 qualified | Acceptable for commercial/industrial indicators but not certified for automotive signal lighting | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated and chromaticity match is secondary |
Compared with VLMW41S1T2-6K6L-08, the VLMW41S1T2-7K8L-08 offers identical form-factor and intensity but shifts chromaticity toward warmer white, while OSRAM LWT67C-6K6L provides mechanical compatibility without automotive qualification - making VLMW41S1T2-6K6L-08 the only option meeting both AEC-Q101 and precise 6K6L binning requirements.

FAQ
What is the luminous intensity range of the VLMW41S1T2-6K6L-08 at 10 mA?
The VLMW41S1T2-6K6L-08 delivers a luminous intensity range of 180–450 mcd at 10 mA, corresponding to its T2 intensity bin classification. This range reflects factory-tested values under standardized 25 ms pulse conditions with ±11% measurement accuracy, and each reel ships with a single intensity group - no mixing across bins. The VLMW41S1T2-6K6L-08 is specified for use in applications where consistent brightness across production units is critical, such as automotive side markers.
Does the VLMW41S1T2-6K6L-08 support reflow soldering, and what profile should be used?
Yes, the VLMW41S1T2-6K6L-08 is fully compatible with Pb-free reflow soldering per J-STD-020, with a peak temperature of up to 260 °C for ≤100 s. Vishay specifies a ramp-up rate ≤3 °C/s, preheat (150–200 °C) for 60–120 s, and time above liquidus (217 °C) of 30–60 s. The VLMW41S1T2-6K6L-08 has undergone JEDEC Level 2a preconditioning, so baking is unnecessary if assembled within 672 hours of dry-pack opening at <30 °C/60% RH.
What does the "6K6L" suffix in VLMW41S1T2-6K6L-08 indicate?
The "6K6L" suffix in VLMW41S1T2-6K6L-08 identifies its chromaticity bin: "6K" denotes the x-coordinate group (0.313, 0.284) and "6L" the y-coordinate group (0.330, 0.347), resulting in a final CIE 1931 coordinate of (0.33, 0.33). This binning ensures tight color consistency across production lots and is verified per packing unit. The VLMW41S1T2-6K6L-08 is therefore selected when precise white-point matching is required - for example, in multi-LED automotive lighting arrays.
Is the VLMW41S1T2-6K6L-08 suitable for automotive applications?
Yes, the VLMW41S1T2-6K6L-08 is AEC-Q101 qualified, confirming its reliability for automotive lighting functions including brake lights, turn signals, side markers, and interior backlighting. It meets operating temperature requirements (-40 °C to +100 °C), has 2 kV HBM ESD rating, and is validated for thermal cycling and humidity exposure per automotive stress test standards. The VLMW41S1T2-6K6L-08 is explicitly referenced in Vishay's documentation for exterior and interior automotive lighting use cases.
What is the maximum continuous forward current rating for the VLMW41S1T2-6K6L-08?
The absolute maximum DC forward current for the VLMW41S1T2-6K6L-08 is 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated lumen depreciation and junction temperature rise beyond the 110 °C limit. For reliable long-term operation, Vishay recommends driving the VLMW41S1T2-6K6L-08 at 10–15 mA in most applications - especially in enclosed or high-ambient-temperature environments - to maintain thermal margin and color stability over lifetime.
