Product details
Overview
TLWY8600 from Vishay Semiconductors is a high-flux, non-diffused yellow AlInGaP-on-GaAs LED in a 7.62 mm square TELUX package, rated for 70 mA DC forward current, 2000–3200 mlm luminous flux at 70 mA, and dominant wavelength 585–597 nm. It delivers stable optical output in automotive exterior lighting and dashboard illumination under ambient temperatures from –40 °C to +110 °C.
For engineers reviewing the TLWY8600 datasheet, TLWY8600 pinout, TLWY8600 application, or TLWY8600 equivalent, this page provides verified thermal resistance (RthJP = 90 K/W), AEC-Q101 qualification status, SAE/ECE-compliant yellow color binning, wave-solder compatibility per J-STD-020, and ESD withstand voltage of 2 kV - all critical for high-reliability vehicle lighting design.
Technical Context
The TLWY8600 uses AlInGaP-on-GaAs epitaxial technology to achieve high-efficiency yellow emission with tight dominant wavelength control (585–597 nm) and low forward voltage (1.83–2.67 V at 70 mA). Its thermal design enables operation up to +110 °C ambient with RthJP = 90 K/W and RthJA = 200 K/W when mounted on a 70 mm² cathode heatsink.
Optical performance is defined by ±30° angle of half intensity and 75° total included angle capturing 90% of total flux. Luminous flux, forward voltage, and dominant wavelength are binned per tube to ensure uniform light appearance in multi-LED arrays used in tail/stop/turn signal modules.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| High luminous flux density | 3200 mlm max at 70 mA in 7.62 mm² footprint - replaces incandescent bulbs with lower power and longer life |
| Supreme heat dissipation | RthJP = 90 K/W - enables >90% luminous flux retention at +85 °C ambient without forced air |
| Tight optical binning | Luminous flux, dominant wavelength, and forward voltage binned per tube - ensures consistent color and brightness across production batches |
| Automotive-grade qualification | AEC-Q101 compliant with SAE/ECE yellow color compliance - approved for safety-critical exterior lighting functions |
| Wave-solder compatible | Rated per CECC 00802 and J-STD-020 - supports high-yield reflow and wave soldering without lens degradation or delamination |

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED emitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLWR8600 | Red variant (611–634 nm); identical package, flux range (2000–3700 mlm), and thermal specs | Used for brake/tail lamp red channels; not interchangeable for yellow turn signal color compliance | Select TLWR8600 only when red spectral output and SAE/ECE red certification are required |
| TLWY8601 | Same yellow TELUX family but rated for 100 mA IF; higher flux (2500–3800 mlm); RthJP = 85 K/W | Requires upgraded driver and thermal layout; not drop-in for 70 mA designs | Choose TLWY8601 only when system-level thermal margin allows 100 mA operation and higher brightness is needed |
Compared with TLWR8600 and TLWY8601, the TLWY8600 offers optimal balance of yellow chromaticity compliance, 70 mA drive simplicity, and proven thermal performance in constrained automotive PCB layouts - making it the preferred choice for cost-sensitive, volume-production turn signal modules.

FAQ
What is the maximum continuous forward current rating for TLWY8600?
The TLWY8600 is rated for 70 mA DC forward current at ambient temperatures ≤ 85 °C. At higher ambient temperatures, derating is required per Fig. 1 in the datasheet; operation at 70 mA is permitted up to +110 °C only when thermal resistance to ambient (RthJA) is maintained at ≤ 200 K/W via adequate PCB heatsinking. Exceeding 70 mA risks junction temperature exceeding 125 °C and accelerated lumen depreciation.
Does TLWY8600 meet automotive regulatory requirements for yellow turn signals?
Yes, TLWY8600 meets SAE and ECE color requirements for yellow automotive lighting. Its dominant wavelength range of 585–597 nm falls within ECE R112 and SAE J578 Category I yellow specifications. Each production tube is binned for wavelength, ensuring batch-to-batch consistency required for regulatory certification of final lamp assemblies containing TLWY8600.
What is the thermal resistance junction-to-pin (RthJP) value for TLWY8600, and how is it measured?
The TLWY8600 has a specified thermal resistance junction-to-pin (RthJP) of 90 K/W. This value is measured with the cathode terminal soldered to a standardized 70 mm² copper pad on FR-4 PCB, per JEDEC JESD51-14. It reflects the intrinsic thermal path from LED junction to the cathode metallization - a key parameter for estimating junction temperature when designing heatsink footprints and selecting board stack-up.
Can TLWY8600 be wave soldered, and what process standards does it comply with?
Yes, TLWY8600 is qualified for wave soldering per CECC 00802 and J-STD-020. Its package construction and epoxy lens withstand peak temperatures up to 260 °C for ≤ 5 s at 1.5 mm from the body, with preheat at 100 °C for 30 s. No special flux or nitrogen atmosphere is required, enabling integration into standard automotive electronics manufacturing lines without process modification.
How is luminous flux binned for TLWY8600, and what does the 'D' flux group indicate?
TLWY8600 is binned for luminous flux into groups D–L per the Luminous Flux Classification table. Group D corresponds to 2000–3000 mlm at 70 mA. Each tube contains LEDs from only one flux group, one wavelength group, and one forward voltage group - ensuring optical uniformity in multi-LED arrays. The 'D' group is the base flux tier, selected for cost-sensitive applications where minimum 2000 mlm output satisfies photometric requirements.
