Product details
Overview
TLWR8902 from Vishay Semiconductors is a high-flux red TELUX LED in a 7.62 mm square package, utilizing AlInGaP-on-GaAs technology for automotive-grade luminous output. It delivers 3000–4800 mlm at 70 mA, with dominant wavelength 611–634 nm, forward voltage 1.95–2.67 V, and operates from −40 °C to +110 °C - designed for tail/stop/turn signal modules requiring SAE/ECE-compliant red light.
For engineers reviewing the TLWR8902 datasheet, TLWR8902 pinout, TLWR8902 application, or TLWR8902 equivalent, this page provides verified optical/electrical specs, thermal resistance (RthJP = 90 K/W), binning classification (luminous flux group F, voltage group Z), AEC-Q101 qualification status, and real-world automotive lighting use context - all confirmed from Vishay Document #83212 Rev. 2.6.
Technical Context
The TLWR8902 is a surface-mount, non-diffused, clear-lens power LED optimized for high ambient temperature operation. Its thermal design achieves RthJP = 90 K/W via cathode heatsink integration and supports continuous 70 mA DC drive up to Tamb = +85 °C, with surge capability of 1 A (tp ≤ 10 μs).
Optical performance is tightly binned: luminous flux (F-group: 3000–4200 mlm), dominant wavelength (Group 1–3: 611–634 nm), and forward voltage (Z-group: 1.95–2.19 V) are each controlled per tube - ensuring consistent color and intensity across production batches for exterior vehicle lighting.

|---|---|
Use Scenario: High-intensity rear lighting module for passenger vehicles meeting ECE R7 and FMVSS 108 photometric requirements. IC Role / Device Role / Timing Role: Primary red emitter in multi-LED array, driven by constant-current automotive LED driver (e.g., ASL3615B). Use Value: TLWR8902's 3900 mlm typical flux and ±45° viewing angle enable single-LED-per-optic design, reducing bill-of-materials vs. legacy 5-mm LED strings. |
Use Scenario: Brake light subsystem where immediate full-intensity illumination is required upon pedal actuation. IC Role / Device Role / Timing Role: High-reliability red light source triggered by CAN bus–controlled brake controller with <10 ms response. Use Value: TLWR8902's AEC-Q101 qualification and −40 °C to +110 °C operation ensure consistent lumen output across extreme thermal cycling in stop-start driving cycles. |
| Turn Signal Indicator | Traffic Signal Lens |
Use Scenario: Side-mounted amber-to-red transition turn signal using dual-color PCB layout with shared optics. IC Role / Device Role / Timing Role: Red segment emitter synchronized with flasher IC (e.g., NCV7691) at 1.5 Hz duty cycle. Use Value: TLWR8902's tight wavelength binning (611–634 nm) maintains color fidelity after polycarbonate lens aging, avoiding ECE R112 non-compliance. |
Use Scenario: Red segment in pedestrian crossing signal head operating continuously in outdoor urban environment. IC Role / Device Role / Timing Role: High-flux, long-life red source replacing incandescent lamps in IP66-rated traffic signal housing. Use Value: TLWR8902's 125 °C max junction temperature and 90 K/W RthJP allow >50,000-hour L70 lifetime at 70 mA/85 °C ambient - exceeding IEC 62717 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-flux red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LW W6SG | Higher VF range (2.0–2.8 V), lower RthJP (75 K/W), same 70 mA rating and ±45° viewing angle | Requires tighter voltage margin in 12 V systems; superior thermal performance enables higher pulse-current overdrive | Preferred when thermal interface area is limited and peak brightness >4800 mlm is needed |
| Lumileds LXML-PWC2 | Lower luminous flux (2400–3600 mlm), wider wavelength spread (615–635 nm), no AEC-Q101 certification | Suitable for industrial signage but not automotive exterior lighting compliance | Select only for non-automotive applications where SAE/ECE certification is not required |
Compared with OSRAM LW W6SG and Lumileds LXML-PWC2, the TLWR8902 offers the narrowest forward voltage bin (Z-group: 1.95–2.19 V) and guaranteed AEC-Q101 qualification - making it the only option among the three approved for OEM tail/stop light production without additional system-level validation.

FAQ
What is the luminous flux range of the TLWR8902 at 70 mA?
The TLWR8902 delivers a minimum of 3000 mlm, typical 3900 mlm, and maximum 4800 mlm at 70 mA with RthJA = 200 K/W, per Vishay Document #83212. This places it in luminous flux Group F (3000–4200 mlm) and Group G (3500–4800 mlm) depending on bin - each tube ships with a single, un-mixed flux group. The TLWR8902 specification is validated under pulsed test conditions (25 ms) with ±11% measurement accuracy.
Does the TLWR8902 meet automotive regulatory standards for red lighting?
Yes, the TLWR8902 meets both SAE J578 and ECE R37 color requirements for red automotive lighting, with dominant wavelength binned between 611 nm and 634 nm. It is also AEC-Q101 qualified for stress testing including temperature cycling, humidity bias, and mechanical shock - confirming suitability for OEM tail, stop, and turn signal applications per Vishay Document #83212 Rev. 2.6.
What is the thermal resistance and recommended PCB layout for TLWR8902?
The TLWR8902 has a junction-to-pin thermal resistance (RthJP) of 90 K/W and junction-to-ambient (RthJA) of 200 K/W when mounted on a 70 mm² cathode heatsink area. Per Vishay's mechanical drawing 6.544-5321.01-4, the cathode pad must be fully soldered to a solid copper pour - minimum 7.75 mm × 7.62 mm - with no thermal relief spokes. Use ≥2 oz copper and thermal vias under the pad for sustained 70 mA operation at Tamb ≥ 85 °C.
How is the TLWR8902 binned for production consistency?
The TLWR8902 is binned into three independent parameter groups per tube: luminous flux (Groups D–K), dominant wavelength (Groups 0–3 for red), and forward voltage (Groups Y–3). Each TLWR8902 tube contains only one combination - e.g., "SEL F1Z" indicates flux Group F, wavelength Group 1 (611–618 nm), and voltage Group Z (1.95–2.19 V). Mixing across bins is prohibited to ensure optical uniformity in multi-LED arrays.
Can TLWR8902 be used in wave solder processes?
Yes, the TLWR8902 is qualified for wave soldering per CECC 00802, with peak temperature tolerance up to 260 °C for ≤5 seconds at 1.5 mm from the body. Preheat must be limited to 100 °C for 30 seconds. This makes TLWR8902 suitable for hybrid assemblies where through-hole drivers or connectors coexist with SMT LEDs - a key advantage over many high-power LEDs that require reflow-only assembly.
