Product details
Overview
VLMW1301-GS08 from Vishay Semiconductors is a white surface-mount 0603 ChipLED using InGaN blue die with yellow phosphor converter, delivering 90–180 mcd luminous intensity at 5 mA, 2.70–3.00 V forward voltage, and ±65° viewing angle - designed for compact indicator and backlighting applications in telecommunication and office equipment.
For engineers reviewing the VLMW1301-GS08 datasheet, VLMW1301-GS08 pinout, VLMW1301-GS08 application, or VLMW1301-GS08 equivalent, key selection criteria include chromaticity coordinates (x=0.294, y=0.286), CIE 1931 white bin S4, JEDEC Level 2a moisture sensitivity, and IR reflow compatibility in high-reliability small-form-factor designs.
Technical Context
The VLMW1301-GS08 is a monolithic white LED chip constructed with an InGaN blue-emitting die coupled to a yellow phosphor-converter epoxy matrix; light mixing yields a correlated color temperature of 7000 K. Its optical output is characterized by a Lambertian emission profile with ±65° half-intensity angle.
Electrically, it operates within a DC forward current limit of 20 mA and thermal resistance of 550 K/W, rated for ambient temperatures from –20 °C to +80 °C. The device is ESD-sensitive and requires handling per JESD22-A112 Level 2a protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous Intensity | 90–180 mcd at 5 mA - defines visible brightness level for indicator visibility under standard drive conditions |
| Forward Voltage | 2.70–3.00 V at 5 mA - determines minimum supply headroom and series resistor sizing |
| Chromaticity Coordinates | x = 0.294, y = 0.286 (CIE 1931) - specifies S4 white bin for consistent color matching across production reels |
| Viewing Angle | ±65° - sets angular spread for uniform illumination in narrow-bezel or wide-distribution applications |
| Package Dimensions | 1.6 mm × 0.8 mm × 0.55 mm - enables placement in space-constrained PCB layouts typical of 0603 footprints |
| Thermal Resistance | 550 K/W junction-to-ambient - constrains maximum power dissipation to 70 mW at 25 °C ambient |
| Moisture Sensitivity | JEDEC Level 2a - mandates dry-pack storage and ≤672 h factory floor time before reflow |
Pinout & Package
Package: SMD 0603 ChipLED (1.6 mm × 0.8 mm × 0.55 mm) with cathode-marked anode/cathode terminals; compatible with EIA standard tape-and-reel (3000 pcs/reel) and IR reflow soldering per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive LED terminal | Connected to current-limiting resistor or constant-current driver output; polarity must match PCB silkscreen marking |
| Cathode | Negative LED terminal | Marked by cathode notch on package body; tied to ground or low-side switch node in driving circuit |
Key Features
| Feature | Design Value |
|---|---|
| Super-thin 0.55 mm height | Enables integration into ultra-low-profile assemblies such as slim keypads and membrane switches |
| InGaN/yellow converter technology | Delivers stable 7000 K white light with minimal chromatic shift over lifetime and temperature |
| JEDEC Level 2a preconditioning | Ensures robustness against popcorning during lead-free reflow without pre-bake under controlled humidity exposure |
| High reliability PCB mounting | Validated for long-term operation in industrial environments with –20 °C to +80 °C ambient range |
| EIA-standard 0603 footprint | Supports automated pick-and-place and standard stencil printing processes without custom tooling |
Applications
| Telecom Indicator | Audio/Video Backlight |
|---|---|
Use Scenario: Status indication on VoIP desk phones and fax machines where space is limited and visual clarity is critical under varying ambient light. IC Role / Device Role / Timing Role: Light-emitting component providing user-visible status feedback; no timing or control function. Use Value: High 90–180 mcd output ensures legibility at viewing distances up to 2 m, while 0603 size allows dense front-panel layout. | Use Scenario: Edge-lit backlight for front-panel buttons and displays in home theater receivers and portable media players. IC Role / Device Role / Timing Role: Discrete white-light source driven by constant-current LED driver ICs; no signal processing role. Use Value: ±65° viewing angle provides even illumination across small symbols without secondary optics, reducing BOM count. |
| Office Equipment Backlight | Indoor Message Board |
Use Scenario: Keypad and function-key illumination in multifunction printers and scanners operating in mixed lighting environments. IC Role / Device Role / Timing Role: Passive optical emitter powered by microcontroller GPIO or dedicated LED driver; no timing dependency. Use Value: 7000 K color temperature matches daylight-balanced LCDs, improving perceived contrast and reducing eye fatigue. | Use Scenario: Pixel-level illumination in segmented alphanumeric message boards used in retail signage and building directories. IC Role / Device Role / Timing Role: Individual light point in multiplexed LED array; driven via row/column scanning with PWM dimming. Use Value: Tight chromaticity bin (S4) ensures uniform white appearance across hundreds of units without manual sorting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar white SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Lumileds LXML-PWC1-0080 | Higher 80 lm/W efficacy; 3535 package (3.5 mm × 3.5 mm); 120° viewing angle; 5700 K CCT | Suitable for higher-brightness, wider-area illumination; not space-compatible with 0603 footprint | Select when luminous flux >5 cd required and board area permits larger package |
| OSRAM LO T671 | 0603 size; 115–230 mcd at 5 mA; x=0.313, y=0.329 (6500 K); JEDEC Level 3 moisture sensitivity | Requires stricter dry storage (<168 h floor life); warmer white tone affects color-matching in multi-LED arrays | Select when warmer white point is acceptable and tighter moisture control is feasible in SMT line |
Compared with VLMW1301-GS08, the Lumileds LXML-PWC1-0080 offers greater optical output but demands significant PCB real estate, while the OSRAM LO T671 matches the 0603 footprint yet introduces longer floor-life constraints and a perceptibly warmer white point - making VLMW1301-GS08 optimal for space-constrained, high-consistency, mid-brightness indicator use.

FAQ
What is the exact chromaticity coordinate specification for VLMW1301-GS08?
The VLMW1301-GS08 is binned to the S4 chromaticity group per CIE 1931, with confirmed coordinates x = 0.294 and y = 0.286 at 5 mA drive current. This bin ensures tight white-point consistency across production reels and eliminates need for post-assembly color sorting in multi-LED arrays.
Does VLMW1301-GS08 support lead-free reflow soldering?
Yes, VLMW1301-GS08 is qualified for lead-free IR reflow per J-STD-020C, with peak temperature up to 260 °C for ≤10 s. Its packaging includes JEDEC Level 2a preconditioning, and the recommended profile specifies ramp rates ≤3 °C/s (up) and ≤6 °C/s (down) to prevent thermal shock.
What is the maximum continuous forward current rating for VLMW1301-GS08?
The absolute maximum DC forward current for VLMW1301-GS08 is 20 mA at ambient temperatures ≤25 °C. At higher ambient temperatures, derating applies per Fig. 1 in the datasheet; sustained operation above 15 mA requires thermal management due to its 550 K/W junction-to-ambient resistance.
How is luminous intensity measured for VLMW1301-GS08, and what tolerance applies?
Luminous intensity for VLMW1301-GS08 is measured using a 25 ms current pulse at 5 mA, with a test accuracy of ±15 %. The specified range of 90–180 mcd reflects production binning (Q2/R1/R2 groups), and each reel ships with only one intensity group to ensure batch uniformity.
Is VLMW1301-GS08 suitable for outdoor applications?
VLMW1301-GS08 is rated for operating temperatures from –20 °C to +80 °C and features epoxy encapsulation resistant to humidity and UV degradation, but it lacks IP-rated sealing or lens-based weatherproofing. It is appropriate for sheltered outdoor message boards but not direct-exposure environments without additional mechanical protection.
