Vishay Semiconductor Opto Division VLWR9930

Overview

VLWR9930 from Vishay Semiconductors is a high-flux, non-diffused red LED in a 7.62 mm square TELUX package, using AlInGaP-on-Si technology. It delivers 4000–12,200 mln luminous flux at 70 mA, with dominant wavelength 611–634 nm, forward voltage 1.83–3.03 V, and operates from −40 °C to +110 °C for automotive exterior lighting.

For engineers reviewing the VLWR9930 datasheet, VLWR9930 pinout, VLWR9930 application, or VLWR9930 equivalent, this page provides verified optical/electrical specs, AEC-Q101 qualification status, thermal resistance (RthJP = 90 K/W), SAE/ECE red color compliance, and binned luminous flux/voltage/wavelength data for precise automotive signal design.

Technical Context

The VLWR9930 is a surface-mount, single-die red LED optimized for high ambient temperature operation up to +110 °C, with junction-to-pin thermal resistance of 90 K/W and junction-to-ambient (with 70 mm² cathode heatsink) of 200 K/W. Its ±45° half-intensity angle and 100° total included angle support focused beam control in reflector-based systems.

It uses AlInGaP-on-Si die technology for stable red emission, meets AEC-Q101 stress testing requirements, and is binned per tube for luminous flux (H–L groups), forward voltage (Y–6 groups), and dominant wavelength (1–3 groups) to ensure consistent photometric performance across production lots.

FAQ

What is the maximum continuous forward current for VLWR9930?

The VLWR9930 has a DC forward current rating of 70 mA at ambient temperatures ≤ 85 °C. At higher ambient temperatures, derating is required per Fig. 1 in the datasheet; for example, at +110 °C ambient, the permissible continuous current drops to approximately 35 mA to maintain junction temperature ≤ 125 °C. The VLWR9930 must be mounted on a ≥70 mm² copper heatsink to achieve its rated RthJA = 200 K/W.

Does VLWR9930 meet automotive regulatory requirements for red color?

Yes, the VLWR9930 meets both SAE J578 and ECE R37 requirements for red exterior lighting due to its dominant wavelength range of 611–634 nm and strict per-tube binning into wavelength groups 1–3. Each production tube carries a selection code indicating its exact dominant wavelength group, ensuring certified color compliance without post-production filtering or calibration.

What thermal interface is required to achieve the published RthJP of 90 K/W for VLWR9930?

To achieve the specified RthJP = 90 K/W, the VLWR9930 cathode pad must be soldered directly to a minimum 70 mm² copper area on the PCB, with ≥2 oz copper thickness and thermal vias connecting to inner or back-side ground planes. No thermal interface material (TIM) is required between the cathode pad and PCB - the solder joint itself forms the primary thermal path. The datasheet specifies RthJP measurement with cathode heatsink of 70 mm².

How is luminous flux binned for VLWR9930, and what does the "H" group mean?

The VLWR9930 is binned into luminous flux groups H–L per tube, with group H defined as 4000–6100 mln at 70 mA. Each tube contains LEDs from only one flux group, one forward voltage group (e.g., Y, Z, 0–6), and one wavelength group (1–3). This ensures photometric uniformity across all units in a given tube, eliminating visible brightness variation in multi-LED lamp arrays. The VLWR9930 shipped in group H guarantees minimum 4000 mln output.

Is VLWR9930 compatible with standard wave soldering processes?

Yes, the VLWR9930 is qualified for wave soldering per CECC 00802, with a peak solder temperature of 260 °C for ≤5 seconds at 1.5 mm from the package body. Preheating to 100 °C for 30 seconds is recommended. The device's construction and leadframe plating support reliable wetting and mechanical integrity during automated through-hole replacement processes, making it suitable for high-volume automotive PCB assembly.
