Product details
Overview
VLMW41S1T1-5K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN blue die with TAG phosphor conversion, delivering 180–355 mcd luminous intensity at 10 mA, ±60° viewing angle, and 3.3–4.2 V forward voltage at 20 mA, designed for automotive signal lighting and indicator applications.
For engineers reviewing the VLMW41S1T1-5K8L-08 datasheet, VLMW41S1T1-5K8L-08 pinout, VLMW41S1T1-5K8L-08 application, or VLMW41S1T1-5K8L-08 equivalent, key selection criteria include chromaticity binning (CIE 1931 x=0.33, y=0.33), AEC-Q101 qualification, PLCC-2 package thermal resistance (360 K/W), and JEDEC level 2a moisture sensitivity handling.
Technical Context
This device employs a blue InGaN LED chip on sapphire substrate, optically coupled to a TAG phosphor-epoxy mixture inside a white thermoplastic PLCC-2 reflector cavity, enabling correlated color temperature of ~5500 K and stable chromaticity under forward current variation.
It operates within -40 °C to +100 °C ambient range, supports reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802, and features ESD withstand up to 2 kV (JESD22-A114-B), with junction temperature limited to 110 °C and maximum DC forward current of 20 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 180–355 mcd at 10 mA - defines visible brightness in indicator and signaling use cases |
| Forward Voltage | 3.3–4.2 V at 20 mA - determines driver voltage headroom and power dissipation (max 84 mW) |
| Chromaticity Coordinates | CIE 1931 x=0.33, y=0.33 - ensures consistent white point for color-matching in multi-LED arrays |
| Viewing Angle | ±60° half-intensity - provides wide beam pattern suitable for panel indicators and marker lights |
| Junction-to-Ambient Thermal Resistance | 360 K/W on >16 mm² PCB pad - constrains thermal design for sustained operation at 20 mA |
| AEC-Q101 Qualified | Validated for automotive-grade reliability - enables use in brake lights, turn signals, and interior lighting |
| Moisture Sensitivity Level | JEDEC Level 2a - requires dry storage or baking if exposed >672 h at ≤30 °C / 60 % RH before reflow |
Pinout & Package
Package: PLCC-2 (Plastic Leaded Chip Carrier, 2-terminal), 3.5 mm × 1.75 mm body, 2.8 mm lead pitch, with anode (A) and cathode (C) terminals identified per Vishay mechanical drawing. Mounting pad layout requires ≥16 mm² copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source; polarity must be observed - reverse operation not permitted |
| Cathode (C) | Negative terminal | Connected to ground or current sink; internal protection diode not integrated |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/Tag phosphor on sapphire | Enables high-efficiency white light generation with stable 5500 K CCT and minimal spectral shift over temperature |
| AEC-Q101 qualification | Confirms suitability for automotive signal lighting including brake and turn indicators without derating |
| PLCC-2 package with white thermoplastic reflector | Provides high reflectivity and thermal stability while supporting automated SMT assembly and JEDEC-compliant reflow |
| Chromacity binned per CIE 1931 | Ensures consistent x/y coordinates (0.33, 0.33) across production reels - critical for uniform appearance in multi-LED systems |
| ESD withstand: 2 kV HBM | Reduces risk of field failure during handling and board assembly without requiring external protection circuitry |
Applications
| Automotive Brake Lights | Camera Flash Lighting |
|---|---|
|
Use Scenario: High-reliability rear lighting module requiring fast response, thermal stability, and regulatory compliance. IC Role / Device Role / Timing Role: Discrete white LED emitter providing visual indication with defined luminous intensity and angular distribution. Use Value: AEC-Q101 qualification and ±60° viewing angle ensure visibility across wide angles while meeting automotive photometric standards. |
Use Scenario: Compact, low-power flash illumination in mobile camera modules where space and thermal budget are constrained. IC Role / Device Role / Timing Role: Primary white light source triggered by short-duration current pulses (25 ms). Use Value: Luminous intensity of 180–355 mcd at 10 mA enables sufficient illumination without exceeding 20 mA absolute max rating. |
| Interior Automotive Indicator | Signal & Symbol Luminaire |
|
Use Scenario: Dashboard or center console status indicator requiring long life, consistent color, and low power draw. IC Role / Device Role / Timing Role: Steady-state visible indicator operating continuously at 10–20 mA DC. Use Value: Stable chromaticity (x=0.33, y=0.33) and 5500 K CCT support human-factor readability and brand-aligned lighting aesthetics. |
Use Scenario: Industrial control panel or safety signage requiring clear, unambiguous visual signaling under varied ambient conditions. IC Role / Device Role / Timing Role: Discrete SMD LED used in array-based symbol generation (e.g., "ON/OFF", warning icons). Use Value: Wide ±60° viewing angle and tight chromaticity binning enable uniform brightness and color perception across operator positions. |
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 | Higher luminous intensity (180–450 mcd), same PLCC-2 package and chromaticity bin (7K = x=0.33, y=0.33) | Better suited for applications needing higher brightness without changing layout or drive circuit | Select when >355 mcd output is required; verify thermal margin due to increased optical power |
| OSRAM LWT67C-5K8L | Same chromaticity group (5K8L), comparable luminous intensity, but different package footprint and thermal resistance | Requires PCB redesign due to non-identical PLCC-2 mechanical dimensions and pad layout | Consider only when cross-manufacturer sourcing is mandated; validate solder profile and thermal performance separately |
Compared with VLMW41S1T1-5K8L-08, the VLMW41S1T2-7K8L-08 offers higher luminance in identical form factor, while OSRAM LWT67C-5K8L provides chromaticity-matched alternative at cost of mechanical redesign and thermal validation.

FAQ
What is the maximum continuous forward current rating for VLMW41S1T1-5K8L-08?
The VLMW41S1T1-5K8L-08 has a maximum DC forward current of 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated degradation and thermal runaway, especially given its 360 K/W junction-to-ambient thermal resistance. The device is tested at 10 mA for luminous intensity specification, and operation at 20 mA requires adequate PCB copper area (>16 mm²) to maintain junction temperature below 110 °C.
Is VLMW41S1T1-5K8L-08 suitable for automotive exterior lighting applications?
Yes, VLMW41S1T1-5K8L-08 is AEC-Q101 qualified and explicitly listed for interior and exterior automotive lighting including brake lights, turn lights, side markers, and backlighting. Its operating temperature range (-40 °C to +100 °C), moisture sensitivity level 2a handling requirements, and chromaticity stability under forward current variation make it appropriate for production automotive signal modules.
What does the "5K8L" suffix indicate in VLMW41S1T1-5K8L-08?
The "5K8L" suffix identifies the chromaticity coordinate bin per Vishay's white LED classification: "5K" denotes the x/y coordinate group centered near (0.296, 0.259), while "8L" specifies the luminous intensity group "S1" (180–224 mcd) and the tape/reel option (08 = 1500 pcs/reel). This binning ensures consistent color and brightness across production lots shipped on the same reel.
Can VLMW41S1T1-5K8L-08 be soldered using standard lead-free reflow profiles?
Yes, VLMW41S1T1-5K8L-08 is compatible with lead-free reflow soldering per J-STD-020, with peak temperature up to 260 °C for ≤100 s and time above liquidus (217 °C) limited to ≤30 s. Vishay provides a validated IR reflow profile (Fig. 13) and confirms compatibility with vapor-phase and wave soldering per CECC 00802 - no special prebake is needed if moisture sensitivity level 2a limits are observed.
Does VLMW41S1T1-5K8L-08 include an integrated protection diode?
No, VLMW41S1T1-5K8L-08 does not include an integrated protection diode. The device is not designed for reverse operation, and applying reverse voltage may cause permanent damage. External reverse-polarity protection - such as a series Schottky diode or bridge rectifier - must be implemented in the driving circuit if bidirectional voltage exposure is possible.
