Product details
Overview
TLWY8900 from Vishay Semiconductors is a high-flux, non-diffused yellow AlInGaP-on-GaAs LED in a 7.62 mm square TELUX package, delivering 2000–3200 mln luminous flux at 70 mA with dominant wavelength 585–597 nm and forward voltage 1.83–2.67 V. It operates from −40 °C to +110 °C and is qualified to AEC-Q101 for automotive exterior lighting.
For engineers reviewing the TLWY8900 datasheet, TLWY8900 pinout, TLWY8900 application, or TLWY8900 equivalent, this device supports high-temperature automotive signaling where precise yellow chromaticity, thermal robustness, and binned optical consistency are critical - especially for tail/stop/turn functions requiring SAE/ECE-compliant color stability.
Technical Context
The TLWY8900 uses AlInGaP-on-GaAs die technology optimized for yellow emission, with a ±45° angle of half intensity and 100° total included angle capturing 90% of luminous flux. Its thermal resistance junction-to-pin is 90 K/W, enabling stable operation up to 125 °C junction temperature when mounted on a 70 mm² cathode heatsink.
It is binned per tube for luminous flux (Group D–G), dominant wavelength (Yellow Groups 0–3), and forward voltage (Groups Y–3), ensuring consistent photometric performance across production lots. Reverse voltage rating is 10 V, and ESD withstand is rated at 2 kV per JESD22-A114-B.
Key Specifications

| AEC-Q101 qualified | Qualified for automotive-grade reliability - eliminates need for additional qualification testing |
Pinout & Package
TLWY8900 is a two-terminal surface-mount LED in the industry-standard 7.62 mm × 7.62 mm TELUX package with cathode marking on the top surface. The package features a thermally enhanced cathode pad (7.75 mm × 4.65 mm) and conforms to CECC 00802 wave soldering standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive DC input terminal | Connected to driver output; requires current-limiting resistor or constant-current source |
| Cathode | Negative DC return terminal | Thermally coupled to PCB copper pour; primary heat dissipation path to board |
Key Features
| Feature | Design Value |
|---|---|
| High luminous flux density | 3200 mln max at 70 mA - replaces multiple lower-output LEDs in space-constrained modules |
| Supreme heat dissipation | RthJP = 90 K/W - sustains full brightness at +110 °C ambient without active cooling |
| Automotive color compliance | Yellow binning per Group 0–3 (585–597 nm) - ensures repeatable SAE/ECE-compliant hue across batches |
| Optical binning per tube | Each tube contains only one luminous flux, wavelength, and VF group - eliminates post-assembly sorting |
| Wave solder compatible | Rated for 260 °C peak soldering temperature (5 s, 1.5 mm from body) - supports high-volume automated assembly |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLWR8901 | Red emitter (611–634 nm), higher max flux (4800 mln), same package and thermal specs | Designed for red automotive signaling; not chromatically interchangeable with TLWY8900 | Select TLWR8901 only when red spectral output and SAE/ECE red compliance are required |
| OSRAM LW W6SG | Yellow LED in 7.6 mm² ceramic package, 2800 mln typical at 70 mA, λd = 590 nm, RthJA = 220 K/W | Higher thermal resistance limits usable current at high ambient; no AEC-Q101 certification | Choose OSRAM LW W6SG only for non-automotive, lower-temperature applications where AEC-Q101 is not mandated |
Compared with TLWR8901 and OSRAM LW W6SG, TLWY8900 uniquely delivers yellow chromaticity with AEC-Q101 qualification, 90 K/W junction-to-pin thermal resistance, and production binning aligned to automotive optical consistency requirements - making it the only drop-in yellow solution for safety-critical vehicle lighting.

FAQ
What is the dominant wavelength range of TLWY8900?
The TLWY8900 has a dominant wavelength range of 585–597 nm, binned into Yellow Groups 0–3 per tube. This range satisfies yellow chromaticity requirements for automotive rear lamps and traffic signals. Each TLWY8900 shipment carries a SEL code indicating its exact wavelength group, ensuring consistent color matching in production assemblies.
Is TLWY8900 qualified for automotive use?
Yes, TLWY8900 is AEC-Q101 qualified and designed for automotive applications including tail, stop, and turn signals. It operates reliably from −40 °C to +110 °C ambient, meets SAE/ECE color requirements for yellow, and is manufactured with process controls aligned to automotive quality standards - all confirmed in Vishay Document 83212 Rev. 2.6.
What thermal management is required for TLWY8900 at full 70 mA drive current?
At 70 mA, TLWY8900 dissipates up to 187 mW. With RthJP = 90 K/W, a 70 mm² copper cathode pad reduces junction-to-ambient resistance to 200 K/W. No external heatsink is needed below +85 °C ambient; above that, increasing copper area or adding airflow maintains Tj < 125 °C. Thermal data is validated in Fig. 14 of the TLWY8900 datasheet.
How is TLWY8900 binned, and why does it matter for production?
TLWY8900 is binned per tube for luminous flux (Groups D–G), dominant wavelength (Yellow Groups 0–3), and forward voltage (Groups Y–3). Each tube contains only one combination - eliminating post-assembly optical sorting. This ensures consistent brightness, color, and drive voltage across all units in a given production lot, critical for uniform appearance in multi-LED lamp modules.
Can TLWY8900 be used in wave solder processes?
Yes, TLWY8900 is qualified for wave soldering per CECC 00802, with a peak temperature tolerance of 260 °C for 5 seconds at 1.5 mm from the package body. Its TELUX package construction and termination finish are engineered for compatibility with high-volume automated assembly - confirmed in Section "Compatible with wave solder processes" of the Vishay datasheet.
