Product details
Overview
VLMW41S1T1-5K8L-18 from Vishay Semiconductors is a white surface-mount LED in PLCC-2 package, using InGaN blue die with TAG phosphor conversion to achieve 5500 K correlated color temperature, 275 mcd typical luminous intensity at 10 mA, ±60° viewing angle, and forward voltage of 3.3–4.2 V at 20 mA - deployed in automotive signal lighting and interior backlighting.
For engineers reviewing the VLMW41S1T1-5K8L-18 datasheet, VLMW41S1T1-5K8L-18 pinout, VLMW41S1T1-5K8L-18 application, or VLMW41S1T1-5K8L-18 equivalent, this page delivers verified optical/electrical specs, AEC-Q101 qualification status, JEDEC level 2a moisture sensitivity, reflow compatibility, and chromaticity binning (8L group: x=0.345, y=0.352) for precise color-critical designs.
Technical Context
This device uses a blue InGaN chip on sapphire substrate, optically coupled to a TAG phosphor-epoxy mixture inside a white thermoplastic PLCC-2 reflector cavity; chromaticity is binned per CIE 1931 to ensure consistent white output across production reels.
It operates within -40 °C to +100 °C ambient range, supports JEDEC level 2a preconditioning, withstands 2 kV ESD (HBM), and is rated for 20 mA DC forward current with 360 K/W thermal resistance junction-to-ambient when mounted on ≥16 mm² PCB copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 180–355 mcd at 10 mA - defines visible brightness level for indicator and signaling functions under standard test pulse |
| Forward Voltage | 3.3–4.2 V at 20 mA - determines minimum supply headroom and series resistor sizing in constant-current drive circuits |
| Chromaticity Coordinates | x = 0.345, y = 0.352 (8L bin) - ensures tight color consistency for multi-LED arrays requiring uniform white appearance |
| Viewing Angle | ±60° half-intensity - specifies beam spread for optimal light distribution in panel indicators and marker lights |
| Color Temperature | Typical 5500 K - delivers neutral white light suitable for automotive interior and exterior signaling applications |
| ESD Withstand | 2 kV HBM - confirms robustness against handling-induced electrostatic discharge during assembly |
| 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 × 2.8 mm footprint, 1.75 mm height, with integrated white reflector cavity and solderable metal leads. Lead frame embedded in thermoplastic housing; polarity marked by cathode notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source; must be biased above cathode by ≥3.3 V to emit light |
| Cathode (C) | Negative terminal | Connected to ground or current sink; notch on package identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/Tag phosphor technology | Enables stable 5500 K white light with high efficacy and low thermal drift vs. alternative phosphor systems |
| AEC-Q101 qualification | Confirms suitability for automotive signal lighting without derating or extended reliability testing |

| PLCC-2 package with white reflector | Maximizes light extraction efficiency and provides mechanical robustness for vibration-prone automotive environments |
| Chromacity binning per CIE 1931 | Ensures batch-to-batch color match for multi-LED assemblies in branding-critical lighting zones |
Applications
| Automotive Brake Lights | Interior Dashboard Backlighting |
|---|---|
Use Scenario: High-reliability stop lamp illumination in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Discrete white light emitter driven by constant-current LED driver IC. Use Value: AEC-Q101 qualification and 110 °C junction rating ensure uninterrupted operation under under-hood thermal stress. |
Use Scenario: Uniform edge-lit illumination behind segmented instrument cluster displays. IC Role / Device Role / Timing Role: Surface-mount discrete LED providing localized white backlight with ±60° beam control. Use Value: Tight 8L chromaticity bin (x=0.345, y=0.352) prevents visible color shift across multiple LEDs in same assembly. |
| Exterior Side Marker Lamps | Camera Flash Auxiliary Light |
Use Scenario: Daytime running and parking position indication on vehicle flanks. IC Role / Device Role / Timing Role: Standalone SMD LED powered via automotive body controller PWM dimming. Use Value: 20 mA DC rating and -40 °C to +100 °C operating range support direct integration into exterior lamp housings. |
Use Scenario: Low-power auxiliary illumination for smartphone or IoT camera modules in low-light conditions. IC Role / Device Role / Timing Role: Discrete white LED pulsed at ≤25 ms duration for brief flash events. Use Value: 275 mcd typical intensity at 10 mA enables sufficient scene illumination without overdriving battery-sensitive portable systems. |
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 8L chromaticity bin, same PLCC-2 package, but 240 mcd min luminous intensity at 10 mA (vs. 180 mcd for VLMW41S1T1-5K8L-18) | Approved for identical automotive signaling roles but requires validation of thermal derating curves in high-ambient designs | Select when cross-manufacturer sourcing flexibility is required and luminous intensity margin >60 mcd is acceptable |
| VLMW41S1T2-7K8L-18 | Same Vishay family; higher luminous intensity (180–450 mcd), 7K chromaticity bin (x=0.330, y=0.330), identical package and drive requirements | Better suited for applications needing brighter output or cooler white tone (≈6500 K), but not color-matched to 5K8L bin | Choose when higher brightness or tighter chromaticity tolerance (±0.01) is prioritized over exact 5500 K color point |
Compared with LWT67C-5K8L and VLMW41S1T2-7K8L-18, the VLMW41S1T1-5K8L-18 offers the most balanced combination of 5500 K color point, 180–355 mcd intensity range, and AEC-Q101 compliance - making it optimal for cost-sensitive automotive signaling where color accuracy and thermal resilience are jointly critical.

FAQ
What is the chromaticity bin designation for VLMW41S1T1-5K8L-18?
The VLMW41S1T1-5K8L-18 is binned to the 8L chromaticity group per CIE 1931, with confirmed coordinates x = 0.345 and y = 0.352. This bin ensures consistent neutral white output across production reels and is validated per the Vishay datasheet revision 2.1 (October 2022). The '5K' prefix indicates target 5500 K color temperature, while '8L' specifies the precise coordinate window.
Is VLMW41S1T1-5K8L-18 qualified for automotive applications?
Yes, VLMW41S1T1-5K8L-18 is AEC-Q101 qualified, confirming its reliability for automotive lighting applications including brake lights, turn signals, and side markers. It meets temperature cycling, humidity testing, and mechanical shock requirements defined in the AEC-Q101 stress test standard, and operates across -40 °C to +100 °C ambient range - essential for under-hood and exterior lamp environments.
What is the maximum forward current rating for VLMW41S1T1-5K8L-18?
The absolute maximum DC forward current for VLMW41S1T1-5K8L-18 is 20 mA at ambient temperatures ≤80 °C. Exceeding this limit risks accelerated lumen depreciation and junction overheating. For continuous operation, Vishay recommends driving at ≤20 mA with adequate PCB copper area (≥16 mm²) to maintain junction temperature below 110 °C - the rated maximum.
Does VLMW41S1T1-5K8L-18 support lead-free reflow soldering?
Yes, VLMW41S1T1-5K8L-18 is compatible with lead-free reflow soldering per J-STD-020, with a peak package body temperature limit of 260 °C for ≤10 seconds. The device is preconditioned to JEDEC level 2a and shipped in dry-packed antistatic tape; if exposed to ambient >60 % RH for >672 hours, baking per J-STD-033 is required before reflow.
What does the '-18' suffix indicate in VLMW41S1T1-5K8L-18?
The '-18' suffix in VLMW41S1T1-5K8L-18 denotes the tape-and-reel packaging option: 8000 pieces per GS18 reel (preferred quantity), versus '-08' which indicates 1500 pieces per GS08 reel. Both variants share identical electrical, optical, and mechanical specifications - only packaging quantity and reel dimensions differ.
