Product details
Overview
VLMW41S1T1-8K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN blue die with TAG phosphor conversion, delivering 180–275–355 mcd luminous intensity at 10 mA, ±60° viewing angle, and 3.3–4.2 V forward voltage at 20 mA - deployed in automotive interior/exterior lighting and indicator applications.
For engineers reviewing the VLMW41S1T1-8K8L-08 datasheet, VLMW41S1T1-8K8L-08 pinout, VLMW41S1T1-8K8L-08 application, or VLMW41S1T1-8K8L-08 equivalent, key selection criteria include chromaticity binning (8K: x=0.352, y=0.344), AEC-Q101 qualification, PLCC-2 package thermal resistance (360 K/W), and JEDEC level 2a moisture sensitivity handling.
Technical Context
This device uses a blue InGaN chip on sapphire substrate combined with TAG phosphor in epoxy to produce white light via partial blue-to-yellow wavelength conversion. Its chromaticity is binned per CIE 1931 (8K group: x=0.352, y=0.344) and tested at 10 mA pulse (25 ms).
The PLCC-2 package features a white thermoplastic body with integrated reflector, optimized for reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802. It is not designed for reverse operation and has ESD withstand up to 2 kV (JESD22-A114-B).
Key Specifications

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-8K8L | OSRAM equivalent; same 8K chromaticity bin, ±60° viewing angle, and PLCC-2 package but rated for 30 mA max IF | Higher max current enables higher peak intensity; requires updated current-limiting resistor design | Select when higher luminous output or extended lifetime at 20 mA is required |
| VLMW41S1T2-7K8L-08 | Vishay variant with higher luminous intensity range (180–275–450 mcd) and 7K chromaticity bin (x=0.330, y=0.330) | Bluer white point and wider intensity distribution; may require recalibration of optical feedback loops | Select when tighter chromaticity tolerance (7K) or higher upper-intensity bound is needed |
Compared with LWT67C-8K8L and VLMW41S1T2-7K8L-08, the VLMW41S1T1-8K8L-08 offers balanced luminous output (180–355 mcd), strict 8K white point consistency, and proven AEC-Q101 compliance - making it optimal for cost-sensitive automotive indicator designs where bin fidelity and qualification traceability are prioritized over peak intensity.

FAQ
What is the chromaticity coordinate specification for VLMW41S1T1-8K8L-08?
The VLMW41S1T1-8K8L-08 is binned to the 8K chromaticity group per CIE 1931, with confirmed coordinates x = 0.352 and y = 0.344 at 10 mA drive current. This bin ensures consistent warm-white appearance across production reels and eliminates inter-reel color variation in multi-unit assemblies.
Is VLMW41S1T1-8K8L-08 qualified for automotive applications?
Yes, VLMW41S1T1-8K8L-08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive signal lighting. Its operating temperature range (-40 °C to +100 °C) and junction temperature rating (110 °C) further validate its suitability for under-hood and exterior lamp use.
What is the maximum continuous forward current for VLMW41S1T1-8K8L-08?
The absolute maximum DC forward current for VLMW41S1T1-8K8L-08 is 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated lumen depreciation and thermal runaway; derating is required above 80 °C per the datasheet's forward current vs. ambient temperature curve.
Does VLMW41S1T1-8K8L-08 support automated reflow soldering?
Yes, VLMW41S1T1-8K8L-08 is fully compatible with Pb-free reflow soldering per J-STD-020, with a peak package body temperature limit of 260 °C for ≤10 seconds. Its PLCC-2 package has been validated for ramp rates up to 3 °C/s and cooling rates up to 6 °C/s without delamination or solder joint failure.
How is moisture sensitivity managed for VLMW41S1T1-8K8L-08?
VLMW41S1T1-8K8L-08 is classified JEDEC level 2a, with a floor life of 672 hours at ≤30 °C/60 % RH after dry bag opening. If exposed beyond this window, baking at 60 °C ±5 °C for 96 hours under <5 % RH is required before reflow - a process validated in the official Vishay moisture sensitivity documentation (Doc. #81370).
