Product details
Overview
VLMW41S1T2-JKKL-08 from Vishay Semiconductors is a white surface-mount LED in PLCC-2 package, using InGaN/sapphire die with TAG phosphor conversion, delivering 275 mcd typical luminous intensity at 10 mA, 3.3 V typical forward voltage at 20 mA, and chromaticity coordinates (x=0.30, y=0.28) for consistent 5500 K color temperature - deployed in automotive signal lighting and camera flash modules.
For engineers reviewing the VLMW41S1T2-JKKL-08 datasheet, VLMW41S1T2-JKKL-08 pinout, VLMW41S1T2-JKKL-08 application, or VLMW41S1T2-JKKL-08 equivalent, key selection criteria include luminous intensity binning (S1/T2), CIE 1931 chromaticity group JK, ±60° viewing angle, AEC-Q101 qualification, and JEDEC level 2a moisture sensitivity handling.
Technical Context
This device uses blue InGaN LED die coupled with TAG phosphor to produce white light via partial wavelength conversion; the resulting spectral output peaks near 450 nm and blends with broad yellow emission to achieve stable 5500 K CCT. Its PLCC-2 thermoplastic package integrates a reflective cavity and lead frame optimized for thermal dissipation up to 110 °C junction temperature.
Designed for reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802, the VLMW41S1T2-JKKL-08 features ESD robustness to 2 kV (HBM), operates across –40 °C to +100 °C ambient range, and maintains luminous intensity stability with –0.4 %/K temperature coefficient and –3 mV/K forward voltage drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 275 mcd typical at 10 mA - defines brightness level for indicator and signaling applications under standard drive conditions |
| Chromaticity Coordinates | (x = 0.30, y = 0.28) per CIE 1931 - specifies precise white point within JK bin for consistent color matching in multi-LED arrays |
| Forward Voltage | 3.3 V typical at 20 mA - determines series resistor value or driver compliance voltage in constant-current circuits |
| Viewing Angle | ±60° half-intensity - sets beam spread for uniform illumination in backlighting and symbol lighting |

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-MKNL-08 | Chromaticity (x=0.33, y=0.33) places it in MK bin - warmer white point vs. JK's cooler 5500 K | Better suited for interior ambient lighting where warmer CCT improves perceived comfort | Select when color rendering or human-centric lighting is prioritized over strict 5500 K specification |
| LWT67C-5L1Z1-1Z | OSRAM equivalent with identical PLCC-2 package, ±60° viewing angle, and 270 mcd typical intensity but different phosphor formulation | Same mechanical fit and optical performance; differs in moisture sensitivity level (level 2b vs. 2a) | Use for cross-supply continuity where Vishay sourcing is constrained; verify JEDEC handling protocol alignment |
Compared with VLMW41S1T2-JKKL-08, the MKNL variant shifts CCT upward for warmer appearance while maintaining identical drive characteristics, whereas the OSRAM LWT67C-5L1Z1-1Z offers mechanical and photometric equivalence but requires updated moisture management planning due to differing floor life.

FAQ
What is the chromaticity coordinate specification for VLMW41S1T2-JKKL-08?
The VLMW41S1T2-JKKL-08 has chromaticity coordinates of x = 0.30 and y = 0.28 per CIE 1931, placing it in the JK bin group. This defines its precise white point for consistent color matching in multi-LED assemblies and ensures tight 5500 K correlated color temperature. The coordinates are measured at 10 mA with ±0.01 tolerance and confirmed per production binning.
Is VLMW41S1T2-JKKL-08 qualified for automotive use?
Yes, VLMW41S1T2-JKKL-08 is AEC-Q101 qualified, meaning it has passed stress tests including temperature cycling, humidity bias, and mechanical shock required for automotive semiconductor components. It is approved for use in exterior lighting such as brake lights and turn signals, as well as interior marker lighting in passenger and commercial vehicles.
What is the maximum forward current rating for VLMW41S1T2-JKKL-08?
The absolute maximum DC forward current for VLMW41S1T2-JKKL-08 is 20 mA at ambient temperatures ≤80 °C. Operating above this limit risks accelerated degradation and thermal runaway. For continuous operation, Vishay recommends 10–20 mA depending on thermal management; pulsed operation may allow higher peak currents if duty cycle and pulse width comply with datasheet limits.
Does VLMW41S1T2-JKKL-08 require baking before reflow soldering?
VLMW41S1T2-JKKL-08 is preconditioned to JEDEC level 2a, granting a 168-hour floor life at ≤30 °C / 60 % RH after dry pack opening. If exposed beyond that window or if the humidity indicator card shows >10 % RH, baking is required: 192 hours at 40 °C +5 °C / –0 °C and <5 % RH, or 96 hours at 60 °C ±5 °C and <5 % RH - both validated for reel packaging.
What is the thermal resistance junction-to-ambient for VLMW41S1T2-JKKL-08?
The thermal resistance junction-to-ambient (RthJA) for VLMW41S1T2-JKKL-08 is 360 K/W when mounted on a PCB with pad area >16 mm². This value directly impacts allowable power dissipation: at 20 mA and 3.3 V, power is ~66 mW, yielding ~24 °C junction-to-ambient rise. Larger copper areas or thermal vias reduce RthJA and improve long-term lumen maintenance.
