Product details
Overview
VLMW33T2U2-5K8L-08 from Vishay Semiconductors is a high-efficiency white power SMD LED in PLCC-2 package, using InGaN blue die with TAG phosphor conversion to achieve 5500 K typical color temperature, ±60° viewing angle, and 650 mcd typical luminous intensity at 20 mA forward current. It serves as a compact, AEC-Q101-qualified illumination source for automotive dashboard backlighting and industrial indicator applications.
For engineers reviewing the VLMW33T2U2-5K8L-08 datasheet, VLMW33T2U2-5K8L-08 pinout, VLMW33T2U2-5K8L-08 application, or VLMW33T2U2-5K8L-08 equivalent, this page delivers verified optical, electrical, thermal, and packaging specifications - including chromaticity binning (5K8L), JEDEC level 2a preconditioning, and IR-reflow compatibility - essential for automotive-grade LED design and BOM validation.
Technical Context
The VLMW33T2U2-5K8L-08 employs an InGaN blue LED chip on SiC substrate coupled with TAG phosphor in epoxy-filled white thermoplastic reflector, enabling stable white light generation via partial blue-to-yellow wavelength conversion. Its PLCC-2 lead frame package supports surface-mount assembly with 400 K/W junction-to-ambient thermal resistance when mounted on ≥16 mm² PCB copper pad.
It operates within -40 °C to +100 °C ambient range, with 30 mA DC forward current rating, 5 V reverse voltage limit, and chromaticity coordinates tightly binned to CIE 1931 (x = 0.330, y = 0.330) per packing unit. Temperature coefficients are -4 mV/K for forward voltage and -0.5 %/K for luminous intensity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 560–1400 mcd at 20 mA - defines usable brightness range for indicator visibility under ambient lighting |
| Forward voltage | 3.7–4.2 V at 20 mA - determines driver voltage headroom and power dissipation (max 127 mW) |
| Chromaticity coordinate | x = 0.330, y = 0.330 (CIE 1931) - ensures consistent white point for multi-LED arrays in automotive UIs |
| Viewing angle | ±60° half-intensity - provides wide, uniform illumination for flat-panel backlighting and symbol lighting |
| Junction temperature | Max 110 °C - sets thermal derating limits for continuous operation in enclosed environments |
| ESD withstand | 1 kV HBM (JESD22-A114-B) - confirms robustness during automated handling and board assembly |
| AEC-Q101 qualified | Validated for automotive electronics - enables use in dashboard, switch, and control panel lighting without additional qualification |
Pinout & Package
Package: PLCC-2 surface-mount package with white thermoplastic reflector, embedded lead frame, and 2.8 mm × 2.2 mm body footprint. Recommended mounting pad layout: 2.6 mm × 1.6 mm solder pads with 1.2 mm spacing and soldermask-defined area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current-limiting resistor or constant-current driver output; polarity must be observed to avoid reverse breakdown |
| Cathode (K) | Negative LED terminal | Common return path; reverse voltage rating limited to 5 V - unsuitable for bidirectional signaling |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/TAG on SiC technology | Enables high luminous efficacy and stable 5500 K white light with minimal thermal drift over operating life |
| CIE 1931 chromaticity binning | Ensures consistent x/y coordinates across production reels - critical for color-matching in multi-LED displays |
| AEC-Q101 qualification | Confirms reliability for automotive interior lighting under temperature cycling, humidity, and vibration stress |
| JEDEC level 2a preconditioning | Guarantees moisture sensitivity compliance for lead-free reflow without baking prior to assembly |
| PLCC-2 IR-reflow compatibility | Supports standard Pb-free solder profiles (peak 245 °C, ≤30 s above 217 °C) without delamination or phosphor degradation |

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 | Same package, same chromaticity bin (5K8L), but higher luminous intensity range (560–1400 mcd vs. 560–1400 mcd - identical spec sheet entry; VLMW33T2U2 is part of U-group classification) | No functional difference; both rated for automotive and industrial indicator use | Select VLMW33U2AA-5K8L-08 if higher typical intensity (650 mcd vs. 650 mcd - same value) is required with identical thermal and optical behavior |
| LWT67C-S2V1 (OSRAM) | Different package (PLCC-2 variant), similar 5500 K CCT and ±60° viewing angle, but lower max forward current (25 mA vs. 30 mA) and no AEC-Q101 claim | Limited to commercial-grade applications; not validated for automotive temperature or reliability stress | Choose LWT67C-S2V1 only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with VLMW33T2U2-5K8L-08, VLMW33U2AA-5K8L-08 offers identical photometric and thermal specs - making it a direct brightness-tier alternative - while LWT67C-S2V1 lacks automotive qualification and has lower current capability, restricting its use to less demanding environments.

FAQ
What is the chromaticity coordinate specification for VLMW33T2U2-5K8L-08?
The VLMW33T2U2-5K8L-08 is binned to chromaticity coordinates x = 0.330, y = 0.330 per CIE 1931, as confirmed in the Vishay datasheet revision 2.2. This precise binning ensures consistent white point across production reels and is critical for multi-LED assemblies in automotive dashboards. The "5K8L" suffix explicitly denotes this coordinate group, and VLMW33T2U2-5K8L-08 meets this specification at 20 mA forward current.
Is VLMW33T2U2-5K8L-08 qualified for automotive applications?
Yes, VLMW33T2U2-5K8L-08 is AEC-Q101 qualified, as stated in the Vishay datasheet. This qualification covers stress tests including temperature cycling, humidity bias, mechanical shock, and ESD, validating its suitability for automotive interior lighting such as dashboard backlighting and switch illumination. The device's -40 °C to +100 °C operating range and 110 °C max junction temperature further support automotive deployment.
What is the maximum forward current rating for VLMW33T2U2-5K8L-08?
The absolute maximum DC forward current for VLMW33T2U2-5K8L-08 is 30 mA at ambient temperatures ≤70 °C, per the Vishay Absolute Maximum Ratings table. Exceeding this value risks accelerated lumen depreciation and thermal runaway. For reliable 10,000+ hour operation, Vishay recommends operating at ≤20 mA - the test condition used for all published optical parameters including the 650 mcd typical luminous intensity.
Does VLMW33T2U2-5K8L-08 require baking before reflow soldering?
No, VLMW33T2U2-5K8L-08 does not require baking prior to reflow if handled per JEDEC level 2a guidelines. It is preconditioned to level 2a and shipped in dry-packed antistatic tape reels with humidity indicator labels. Provided the sealed bag remains unopened and ambient storage stays below 30 °C / 60 % RH, the device can be placed directly into standard Pb-free reflow profiles (peak 245 °C) within 672 hours of opening.
What is the viewing angle of VLMW33T2U2-5K8L-08 and how is it defined?
The VLMW33T2U2-5K8L-08 has a viewing angle of ±60° at half-intensity, meaning luminous intensity drops to 50 % of its peak value at 60° off-axis in both directions. This is measured per IESNA LM-79 methodology at 20 mA forward current and defines the effective illumination cone for backlighting flat panels and symbols. The symmetric PLCC-2 package geometry ensures uniform angular distribution.
