Product details
Overview
VLMW41R1T1-7K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN/ TAG phosphor-on-sapphire technology, delivering 275 mcd typical luminous intensity at 10 mA, with chromaticity coordinates (x=0.345, y=0.352) and forward voltage 3.3–4.2 V at 20 mA. It serves as a compact, AEC-Q101-qualified light source in automotive signal lighting and indicator applications.
For engineers reviewing the VLMW41R1T1-7K8L-08 datasheet, VLMW41R1T1-7K8L-08 pinout, VLMW41R1T1-7K8L-08 application, or VLMW41R1T1-7K8L-08 equivalent, key selection criteria include its PLCC-2 package compatibility with reflow soldering, ±60° viewing angle, 5000 K color temperature, ESD withstand voltage (2 kV), and luminous intensity binning (R1/T1 group).
Technical Context
This device employs blue-emitting InGaN die coupled with TAG phosphor in epoxy to generate white light via partial wavelength conversion. Its chromaticity is binned per CIE 1931 (7K/8L coordinate groups), and intensity is categorized by mcd ranges (R1: 112–140 mcd; T1: 280–355 mcd) - the -7K8L-08 suffix confirms dual-coordinate binning and R1/T1 intensity grouping.
Thermally, it features 360 K/W junction-to-ambient thermal resistance when mounted on ≥16 mm² PCB pads, operates from –40 °C to +100 °C, and supports JEDEC level 2a preconditioning. It is not reverse-operable and requires dry-pack handling due to moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 275 mcd typical at 10 mA - defines brightness level for visibility-critical indicators |
| Forward voltage | 3.3–4.2 V at 20 mA - determines driver voltage headroom and power dissipation |
| Chromaticity coordinates | x = 0.345, y = 0.352 (CIE 1931) - ensures consistent 5000 K cool-white appearance across batches |
| Viewing angle | ±60° half-intensity - enables wide-angle illumination without secondary optics |
| ESD withstand voltage | 2 kV HBM - supports robust handling in automated SMT lines without special grounding |
| Thermal resistance | 360 K/W (junction-to-ambient) - constrains max continuous current to 20 mA at ≤80 °C ambient |
| AEC-Q101 qualified | Validated for automotive use - meets stress test requirements for temperature cycling, humidity, and lifetime reliability |
Pinout & Package
The VLMW41R1T1-7K8L-08 uses a standard PLCC-2 (Plastic Leaded Chip Carrier, 2-terminal) SMD package with lead frame embedded in white thermoplastic and internal phosphor-filled reflector. Dimensions: 3.5 ± 0.2 mm × 2.8 ± 0.15 mm × 1.75 ± 0.1 mm (L × W × H); mounting pad layout requires ≥16 mm² copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input terminal | Connected to current-limiting resistor or constant-current driver output; polarity must be observed to avoid damage |
| Cathode (C) | Ground/negative return path | Common reference for LED biasing; PCB trace must support thermal conduction to heatsinking pad |
Key Features
| Feature | Design Value |
|---|---|
| InGaN/ TAG phosphor-on-sapphire die | Enables stable white emission with low thermal droop and high efficiency vs. conventional YAG phosphor LEDs |
| CIE 1931 chromaticity binning (7K/8L) | Guarantees tight color consistency across production reels - critical for multi-LED arrays in automotive lighting |
| Luminous intensity binning (R1/T1) | Ensures uniform brightness within a reel - eliminates manual sorting for indicator and symbol luminaire designs |
| Reflow/wave solder compatible | Supports standard Pb-free reflow profiles (peak 260 °C, ≤120 s) and double-wave processes - simplifies manufacturing integration |
| JEDEC level 2a preconditioning | Confirms moisture sensitivity level - mandates dry storage and bake protocols before reflow to prevent popcorning |

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-5L1-30 | Same PLCC-2 package, but uses AlInGaP/ YAG phosphor; lower efficacy (180 mcd typ.), warmer CCT (~4500 K) | Better suited for indoor signage where warm-white tone is preferred; less suitable for automotive brake lights requiring cool-white compliance | Select LWT67C-5L1-30 only if color temperature tolerance > ±200 K is acceptable and intensity >250 mcd is not required |
| VLMW41R2T2-7K8L-08 | Identical package and binning structure, but higher intensity bin (R2/T2: 140–180 / 224–280 mcd); same chromaticity and electrical specs | Provides brighter output without layout change - ideal for applications needing enhanced visibility in daylight conditions | Choose VLMW41R2T2-7K8L-08 when luminance margin is critical and thermal design accommodates identical power dissipation |
Compared with LWT67C-5L1-30 and VLMW41R2T2-7K8L-08, the VLMW41R1T1-7K8L-08 offers optimal balance of cool-white consistency, moderate intensity, and AEC-Q101 compliance - making it the default choice for cost-sensitive automotive signal and industrial indicator designs where strict 5000 K matching and JEDEC-level reliability are mandatory.

FAQ
What is the maximum continuous forward current rating for the VLMW41R1T1-7K8L-08?
The VLMW41R1T1-7K8L-08 has a DC forward current rating of 20 mA at ambient temperatures ≤80 °C. Exceeding this value risks accelerated lumen depreciation and junction temperature rise beyond the 110 °C limit. Derating is required above 80 °C ambient, per Fig. 1 in the datasheet. The VLMW41R1T1-7K8L-08 must never be operated in reverse bias.
Does the VLMW41R1T1-7K8L-08 require baking before reflow soldering?
Yes - the VLMW41R1T1-7K8L-08 is moisture-sensitive per JEDEC level 2a and must be baked if exposed to ambient conditions >672 hours after opening the dry bag. Recommended bake: 96 hours at 60 °C ±5 °C and <5 % RH. The VLMW41R1T1-7K8L-08 reel carries an EIA JESD22-A112 level 2a label indicating this requirement.
What does the "7K8L" suffix in VLMW41R1T1-7K8L-08 signify?
The "7K8L" denotes dual chromaticity binning: "7K" refers to the x/y coordinate group centered near (0.330, 0.310), and "8L" refers to the group centered near (0.345, 0.352). The VLMW41R1T1-7K8L-08 is binned to meet both specifications, ensuring tighter color consistency than single-bin parts. This is confirmed in the Chromaticity Coordinated Groups table on page 3 of the datasheet.
Is the VLMW41R1T1-7K8L-08 compatible with wave soldering?
Yes - the VLMW41R1T1-7K8L-08 is qualified for vapor-phase, reflow, and wave soldering per CECC 00802 and J-STD-020. Its PLCC-2 package withstands peak wave solder temperatures up to 260 °C for ≤10 seconds (first wave) and ≤5 seconds (second wave), as shown in Fig. 13. The VLMW41R1T1-7K8L-08 must be pre-conditioned per JEDEC level 2a prior to any solder process.
How is luminous intensity binned for the VLMW41R1T1-7K8L-08?
The VLMW41R1T1-7K8L-08 is intensity-binned into R1 (112–140 mcd) and T1 (280–355 mcd) groups per the Parts Table. Each reel contains only one intensity group - no mixing occurs. The "R1T1" in the part number confirms dual-intensity binning, enabling design flexibility while maintaining intra-reel consistency. The VLMW41R1T1-7K8L-08's typical value of 275 mcd falls within the T1 range.
