Product details
Overview
TLWR8900 from Vishay Semiconductors is a high-flux red TELUX power LED in a 7.62 mm square package, utilizing AlInGaP-on-GaAs technology. It delivers 2000–3700 mln luminous flux at 70 mA, with dominant wavelength 611–634 nm, forward voltage 1.83–2.67 V, and operates from −40 °C to +110 °C ambient - designed for automotive exterior lighting requiring high thermal robustness and color compliance.
For engineers reviewing the TLWR8900 datasheet, TLWR8900 pinout, TLWR8900 application, or TLWR8900 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, SAE/ECE red-color compliance, thermal resistance (RthJP = 90 K/W), and binned luminous flux classification - all critical for tail-light, stop-signal, and dashboard illumination design validation.
Technical Context
The TLWR8900 is a surface-mount, non-diffused, clear-lens power LED optimized for directional high-intensity emission. Its ±45° angle of half intensity and 100° total included angle enable precise optical control with external reflectors or lightguides, while its 90 K/W junction-to-pin thermal resistance supports stable operation under high ambient temperatures up to +110 °C.
It uses AlInGaP-on-GaAs die technology for high-efficiency red emission and is binned per tube for luminous flux (Group D: 2000–3000 mln), dominant wavelength (Group 1: 611–618 nm), and forward voltage (Group Y: 1.83–2.07 V), ensuring consistent photometric performance across production lots.

Equivalent & Alternatives
The following parts are listed as comparable options for similar red power LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLWR8901 | Higher luminous flux range (2000–4800 mln); same VF and λd specs | Better suited for applications requiring higher peak intensity (e.g., daytime running lights) | Select TLWR8901 when >3700 mln output is needed without changing thermal layout |
| TLWR8902 | Higher minimum forward voltage (1.95 V min); 3000–4800 mln flux; tighter λd bin (614–622 nm) | Optimized for systems with higher supply headroom and stricter chromaticity control | Choose TLWR8902 where color consistency across temperature and aging is prioritized over lowest VF drop |
Compared with TLWR8900, TLWR8901 offers extended upper flux range for brighter signaling, while TLWR8902 trades lower VF tolerance for improved wavelength stability and higher minimum flux - both share identical package, thermal design, and AEC-Q101 qualification.

FAQ
What is the maximum continuous forward current for TLWR8900?
The TLWR8900 is rated for 70 mA DC forward current at ambient temperatures ≤ 85 °C. At higher ambient temperatures, current must be derated per Fig. 1 in the datasheet. The device supports 1 A surge current for pulses ≤ 10 μs, enabling compatibility with PWM dimming schemes without thermal overstress. TLWR8900 maintains stable output within specification across its full operating range when mounted on a 70 mm² cathode heatsink.
Does TLWR8900 meet automotive regulatory standards for red lighting?
Yes, TLWR8900 meets SAE J578 and ECE R37 chromaticity requirements for red automotive lighting when operated within its specified dominant wavelength range (611–634 nm). Each production tube is binned for wavelength (Group 1: 611–618 nm), ensuring consistent color compliance across units. TLWR8900 is also AEC-Q101 qualified, confirming its suitability for automotive-grade reliability testing.
What thermal management is required for TLWR8900 at 70 mA?
At 70 mA, TLWR8900 requires a minimum 70 mm² copper cathode pad on the PCB to achieve the specified RthJA of 200 K/W. Its RthJP of 90 K/W means heat flows efficiently from junction to cathode pad - so thermal vias and internal copper layers beneath the pad significantly improve steady-state performance. Without adequate heatsinking, junction temperature exceeds 125 °C above 60 °C ambient, triggering luminous flux degradation.
How is TLWR8900 binned, and what does the SEL code indicate?
TLWR8900 is binned per tube for three parameters: luminous flux (Group D: 2000–3000 mln), dominant wavelength (Group 1: 611–618 nm), and forward voltage (Group Y: 1.83–2.07 V). The SEL code on the tube label encodes these bins - e.g., "SELB10" means digit 1 = B (flux group), digit 2 = 1 (wavelength group), digit 3 = 0 (VF group). This ensures photometric uniformity without post-assembly sorting. TLWR8900 shipments contain only one bin combination per tube.
Can TLWR8900 be used in wave soldering processes?
Yes, TLWR8900 is qualified for wave soldering per CECC 00802, withstanding 260 °C peak temperature for 5 seconds at 1.5 mm from the body. Preheat temperature must not exceed 100 °C for more than 30 seconds. The device's clear epoxy lens and robust leadframe construction prevent delamination or discoloration during standard through-hole-compatible reflow or wave profiles. TLWR8900's mechanical tolerances also support precise placement in automated insertion equipment.
