Product details
Overview
VLMW33S2V1-5K8L-08 from Vishay Semiconductors is a white power SMD LED in PLCC-2 package, engineered for high-efficiency illumination with 635 mcd typical luminous intensity at 20 mA, 3.7–4.2 V forward voltage, and ±60° viewing angle. It delivers 5500 K correlated color temperature using InGaN blue die with TAG phosphor on SiC substrate, targeting automotive dashboard backlighting and LCD symbol illumination.
For engineers reviewing the VLMW33S2V1-5K8L-08 datasheet, VLMW33S2V1-5K8L-08 pinout, VLMW33S2V1-5K8L-08 application, or VLMW33S2V1-5K8L-08 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, chromaticity binning (5K8L), thermal resistance (400 K/W), and JEDEC level 2a moisture sensitivity handling guidance.
Technical Context
The VLMW33S2V1-5K8L-08 uses an InGaN blue-emitting chip bonded to silicon carbide (SiC) substrate, coated with TAG phosphor to generate white light via partial blue-to-yellow wavelength conversion. Its PLCC-2 thermoplastic package features an integrated white reflector cavity and lead frame construction optimized for thermal dissipation up to 110 °C junction temperature.
Optical performance is binned per CIE 1931 chromaticity coordinates (x = 0.33, y = 0.33) and luminous intensity (224–900 mcd), with 5K8L denoting specific x/y group and luminance subgroup V. It supports IR reflow, vapor phase, and wave soldering per J-STD-020 and CECC 00802 standards.

Applications
| Automotive Dashboard Backlighting | Office Equipment Indicator Panels |
|---|---|
Use Scenario: Illuminating segmented symbols and analog gauge markings in vehicle instrument clusters under varying ambient light. IC Role / Device Role / Timing Role: Discrete white light source driven by constant-current LED driver IC or microcontroller GPIO with current-limiting resistor. Use Value: ±60° viewing angle ensures even symbol coverage without lensing; AEC-Q101 qualification guarantees operation across –40 to +100 °C ambient range. |
Use Scenario: Providing status indication on multifunction printers, scanners, and copiers with high visibility in office lighting conditions. IC Role / Device Role / Timing Role: Standalone indicator LED powered from 3.3 V or 5 V rail via series resistor; no active control required. Use Value: 635 mcd typical intensity meets IEC 62368-1 visibility thresholds; 5500 K CCT matches daylight-balanced indoor environments. |
| LCD Symbol Backlighting | Telecom Device Keypad Illumination |
Use Scenario: Edge-lit or direct-backlit alphanumeric symbols on industrial HMI displays and consumer audio/video front panels. IC Role / Device Role / Timing Role: Primary illumination element mounted adjacent to transparent overlay; driven continuously or PWM-dimmed. Use Value: Tight chromaticity binning (5K8L) prevents visible color shift between adjacent symbols; PLCC-2 footprint allows dense placement. |
Use Scenario: Backlighting tactile keys on landline telephones and fax machines for low-light usability. IC Role / Device Role / Timing Role: Low-power discrete emitter operated at 20 mA from battery or wall adapter supply. Use Value: 30 mA absolute max rating supports surge tolerance during keypress transients; ESD rating (1 kV HBM) protects against user-handling discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMW33U2AA-5K8L-08 | Higher luminous intensity (560–1400 mcd), same chromaticity bin (5K8L), identical package and VF range | Better suited for applications requiring higher brightness without changing optics or drive circuitry | Select when higher visibility is needed; verify thermal margin due to increased power dissipation at same current |
| LWT67C-S2V1 | OSRAM cross-reference; same PLCC-2 package, ±60° viewing angle, and 5500 K CCT, but different binning structure and JEDEC level 3 moisture sensitivity | Requires updated moisture handling protocol and may exhibit minor chromaticity variance within same nominal bin | Use only if OSRAM sourcing is preferred; confirm reflow profile compatibility and perform optical validation |
Compared with VLMW33S2V1-5K8L-08, VLMW33U2AA-5K8L-08 offers higher luminance headroom while maintaining identical thermal and optical behavior, whereas LWT67C-S2V1 provides second-source availability but introduces moisture sensitivity and binning process differences requiring requalification.

FAQ
What is the luminous intensity range of the VLMW33S2V1-5K8L-08 at 20 mA?
The VLMW33S2V1-5K8L-08 has a luminous intensity range of 224–900 mcd at 20 mA forward current, with 635 mcd as the typical value. This range reflects factory binning into subgroup V (710–900 mcd) per the 5K8L designation, ensuring consistent brightness per reel without mixing groups.
Is the VLMW33S2V1-5K8L-08 qualified for automotive applications?
Yes, the VLMW33S2V1-5K8L-08 is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This makes it suitable for automotive interior lighting such as dashboard and switch backlighting per ISO/TS 16949 requirements.
What does the "5K8L" suffix mean in VLMW33S2V1-5K8L-08?
The "5K8L" suffix identifies the chromaticity and luminous intensity bin: "5K" denotes the CIE 1931 x/y coordinate group centered at (0.33, 0.33), and "8L" specifies luminance subgroup V (710–900 mcd). This dual binning ensures both color consistency and brightness uniformity across production lots.
What is the maximum allowable forward current for continuous operation of VLMW33S2V1-5K8L-08?
The absolute maximum DC forward current for VLMW33S2V1-5K8L-08 is 30 mA at ambient temperatures ≤70 °C. At higher ambient temperatures, derating is required per Fig. 1 in the datasheet; for example, at 85 °C ambient, maximum continuous current drops to approximately 22 mA to maintain Tj ≤110 °C.
Does the VLMW33S2V1-5K8L-08 require special handling during PCB assembly?
Yes, the VLMW33S2V1-5K8L-08 is JEDEC level 2a moisture-sensitive and must be stored in sealed dry bags until use. If exposed to ambient conditions >672 hours at ≤30 °C / ≤60 % RH, baking per J-STD-033 is required prior to reflow. The device supports Pb-free reflow with peak temperature up to 260 °C for <120 s.
