Vishay Semiconductor Opto Division TLWR7600

Overview

TLWR7600 from Vishay Semiconductors is a high-flux, non-diffused red AlInGaP-on-GaAs LED in a 7.62 mm square TELUX package, delivering 1500–2800 mlm luminous flux at 70 mA with dominant wavelength 611–634 nm and forward voltage 1.83–2.67 V. It operates from −40 °C to +110 °C and is AEC-Q101 qualified for automotive exterior lighting.

For engineers reviewing the TLWR7600 datasheet, TLWR7600 pinout, TLWR7600 application, or TLWR7600 equivalent, this page delivers verified optical, thermal, and electrical specifications - including R_thJP = 90 K/W, ±30° half-intensity angle, SAE/ECE red color compliance, and tube-based binning for flux/voltage/wavelength - to support automotive signal and industrial high-temperature LED design.

Technical Context

The TLWR7600 uses AllnGaP-on-GaAs die technology optimized for high radiant output in the red spectrum (611–634 nm dominant wavelength), with thermal resistance junction-to-pin of 90 K/W enabling stable operation up to 110 °C ambient. Its ±30° viewing angle and 75° total included angle support directional illumination without secondary optics.

It is binned per tube for luminous flux (Group B–I), dominant wavelength (Groups 1–3 for red), and forward voltage (Groups Y–3), ensuring consistent photometric performance across production lots. The device meets CECC 00802 and J-STD-020 wave soldering standards and withstands 2 kV ESD per JESD22-A114-B.

FAQ

What is the maximum continuous forward current for TLWR7600?

The TLWR7600 supports a maximum DC forward current of 70 mA at ambient temperatures ≤ 85 °C. At higher ambient temperatures up to 110 °C, derating is required per the datasheet's forward current vs. ambient temperature curve. Exceeding 70 mA risks accelerated lumen depreciation and junction overheating beyond the 125 °C limit. Always verify thermal design using R_thJA = 200 K/W (with heatsink) or R_thJP = 90 K/W in system-level simulations.

Does TLWR7600 meet automotive regulatory requirements for red lighting?

Yes, TLWR7600 meets SAE J575 and ECE R37 color requirements for red automotive lighting, with dominant wavelength binned between 611 nm and 634 nm. Each production tube is labeled with a selection code (e.g., SELB10) indicating its specific luminous flux, wavelength, and forward voltage group - enabling traceable compliance verification in Tier 1 supplier audits and vehicle type approval submissions.

How is luminous flux binned for TLWR7600, and what does "Group D" mean?

TLWR7600 is binned into luminous flux groups A–I per the datasheet table, where Group D corresponds to 2000–3000 mlm at 70 mA. Each tube contains LEDs from only one flux group - no mixing occurs. Group D devices deliver higher output than standard Group B (1000–1800 mlm) units, enabling fewer LEDs per lamp assembly while maintaining target candela levels. The actual group is encoded in the third digit of the SEL code on the tube label.

Can TLWR7600 be wave-soldered, and what are the process limits?

Yes, TLWR7600 is qualified for wave soldering per CECC 00802 and J-STD-020. Peak solder temperature must not exceed 260 °C for ≤ 5 seconds, with preheat at 100 °C for 30 seconds. The cathode pad must remain unmasked to ensure proper thermal relief. Avoid immersion depth exceeding 1.5 mm from body base to prevent mechanical stress on terminals. Post-solder inspection should verify coplanarity and absence of solder bridging between anode and cathode.

What is the thermal resistance junction-to-pin (R_thJP) of TLWR7600, and how is it used in thermal design?

The TLWR7600 has a measured R_thJP of 90 K/W, defined as the thermal resistance from junction to cathode terminal. This value is used to calculate junction temperature when the cathode is directly heatsunk: T_j = T_cathode + (P_diss × 90). For example, at 70 mA and 2.2 V VF, power dissipation is 154 mW; with cathode held at 85 °C, T_j = 85 + (0.154 × 90) ≈ 99 °C - well below the 125 °C absolute maximum.
