Product details
Overview
VLMR333U1AA-GS08 from Vishay Semiconductors is a red surface-mount power LED in PLCC-2 package, delivering 450–1400 mcd luminous intensity at 20 mA, with dominant wavelength 619–631 nm and forward voltage 1.8–2.6 V. It supports automotive-grade reliability (AEC-Q101 qualified), operates from −40 °C to +100 °C, and is used in dashboard illumination and traffic signal indicators.
For engineers reviewing the VLMR333U1AA-GS08 datasheet, VLMR333U1AA-GS08 pinout, VLMR333U1AA-GS08 application, or VLMR333U1AA-GS08 equivalent, key selection criteria include luminous intensity binning (U1 group), thermal resistance (400 K/W), ±60° viewing angle, AlInGaP-on-Si technology, and compatibility with reflow soldering per J-STD-020.
Technical Context
This red power SMD LED uses AlInGaP-on-Si die technology to achieve high radiant output and stable chromaticity across temperature. Its PLCC-2 package integrates a white thermoplastic lead frame and clear epoxy-filled reflector for directional light control and thermal management.
The device is rated for 50 mA DC forward current at ambient ≤73 °C, with absolute maximum junction temperature of 125 °C and reverse voltage tolerance of 5 V (short-term only). It meets JEDEC level 2a preconditioning and AEC-Q101 stress testing for automotive use.

Applications
| Traffic Signal Modules | Automotive Dashboard Indicators |
|---|---|
Use Scenario: Red status indication in LED-based traffic light arrays requiring long-life, high-visibility output under outdoor UV and thermal cycling. IC Role / Device Role / Timing Role: Light-emitting element providing regulated red chromaticity and luminance per IEC 60838 and EN 12367 standards. Use Value: 1400 mcd max intensity ensures legibility at >100 m distance; ±60° viewing angle enables uniform lens coupling without secondary optics. |
Use Scenario: Illumination of instrument cluster symbols (e.g., brake warning, oil pressure) in passenger vehicles operating across −40 °C to +85 °C ambient. IC Role / Device Role / Timing Role: Primary red emitter in multiplexed or constant-current driven backlight circuits. Use Value: AEC-Q101 qualification and 125 °C max junction temperature support sustained operation in confined, unventilated dash cavities. |
| Industrial Control Panel Indicators | Consumer Audio/Video Backlighting |
Use Scenario: Status feedback LEDs on factory HMIs and PLC operator interfaces exposed to dust, vibration, and wide temperature swings. IC Role / Device Role / Timing Role: High-reliability visual indicator replacing incandescent bulbs in panel-mounted pushbuttons and status bars. Use Value: 50 mA max drive capability allows overdrive for pulse-width modulated brightness control while maintaining 400 K/W thermal resistance. |
Use Scenario: Symbol and switch illumination in home theater receivers, soundbars, and portable media players where color fidelity and low power are critical. IC Role / Device Role / Timing Role: Discrete red light source in compact SMT layouts with tight board space constraints. Use Value: PLCC-2 footprint (3.5 × 2.8 mm) enables dense placement; 1.8 V min forward voltage reduces driver losses in battery-powered designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMS333T2V2-GS08 | Super red (626–639 nm), higher luminous intensity (355–1120 mcd), same PLCC-2 package and VF range | Better suited for applications requiring deeper red hue and higher contrast against ambient light | Select when dominant wavelength >625 nm is required for regulatory or perceptual reasons |
| VLMY333U1AA-GS08 | Yellow variant (583–594 nm), identical intensity bin (U1), same thermal and packaging specs | Used where amber/yellow coding is mandated (e.g., caution indicators, dual-color status lights) | Choose for color-coded systems needing spectral separation from red without changing layout or drive circuitry |
Compared with VLMR333U1AA-GS08, VLMS333T2V2-GS08 shifts chromaticity toward super-red for enhanced daylight visibility, while VLMY333U1AA-GS08 provides a spectrally distinct yellow option-both retain identical mechanical fit, thermal performance, and soldering compatibility.

FAQ
What is the maximum continuous forward current rating for VLMR333U1AA-GS08?
The VLMR333U1AA-GS08 has a maximum DC forward current of 50 mA when ambient temperature is ≤73 °C and mounted on a PCB with thermal pad area >16 mm². Exceeding this limit risks junction overheating beyond the 125 °C absolute maximum, accelerating lumen depreciation. Derating is required above 73 °C per Figure 1 in the datasheet. The VLMR333U1AA-GS08 must not be operated continuously above this threshold without thermal analysis.
Does VLMR333U1AA-GS08 require baking before reflow soldering?
No - the VLMR333U1AA-GS08 is preconditioned to JEDEC level 2a and shipped in dry-packed antistatic tape, allowing direct placement into Pb-free reflow profiles (peak 260 °C) within 672 hours of bag opening at <30 °C / 60 % RH. Baking is only required if moisture exposure exceeds limits; the VLMR333U1AA-GS08's level 2a labeling confirms compliance without mandatory bake-out.
What does the 'U1' in VLMR333U1AA-GS08 signify?
The 'U1' in VLMR333U1AA-GS08 denotes the luminous intensity bin: minimum 450 mcd and maximum 560 mcd at 20 mA. This binning ensures brightness consistency across a full reel (1500 pcs), with no mixing of intensity groups. The VLMR333U1AA-GS08 is therefore guaranteed to fall within this narrow output range, critical for uniform appearance in multi-LED arrays.
Is VLMR333U1AA-GS08 compatible with automated optical inspection (AOI)?
Yes - the VLMR333U1AA-GS08's PLCC-2 package features clearly defined anode/cathode markings (notch/dot) and consistent top-surface geometry, enabling reliable detection by standard AOI systems. Its white thermoplastic body provides high contrast against solder paste, and the clear epoxy dome exhibits predictable reflectivity. The VLMR333U1AA-GS08 meets IPC-A-610 Class 2/3 visual acceptability criteria post-reflow.
How does the thermal resistance of 400 K/W affect PCB layout for VLMR333U1AA-GS08?
A thermal resistance of 400 K/W means that with 50 mA drive at 2.2 V (110 mW power dissipation), junction temperature rises ~44 °C above ambient - requiring careful thermal design. To maintain Tj ≤125 °C at 85 °C ambient, the VLMR333U1AA-GS08 must be mounted on a copper pad ≥16 mm² with ≥2 thermal vias to inner/ground planes. Smaller pads increase RthJA and risk premature failure.
