Product details
Overview
VLWR9933 from Vishay Semiconductors is a high-flux red AlInGaP-on-Si power LED in a 7.62 mm square TELUX package, delivering 7000–9500 mln luminous flux at 70 mA with dominant wavelength 611–634 nm and forward voltage 1.95–2.67 V. It operates from −40 °C to +110 °C and meets SAE/ECE automotive color requirements for tail and stop lights.
For engineers reviewing the VLWR9933 datasheet, VLWR9933 pinout, VLWR9933 application, or VLWR9933 equivalent, this page provides verified optical, thermal, and electrical specifications, AEC-Q101 qualification status, binned flux/voltage/wavelength data, and automotive-grade reliability context for exterior vehicle lighting design.
Technical Context
The VLWR9933 uses AlInGaP-on-Si die technology to achieve high radiant efficiency and stable red emission across wide temperature ranges. Its ±45° half-intensity angle and 100° total included angle support directional beam control with external reflectors or lightguides.
Thermal performance is defined by RthJP = 90 K/W (junction-to-pin) and RthJA = 200 K/W (with 70 mm² cathode heatsink), enabling operation up to 125 °C junction temperature. Absolute maximum ratings include 70 mA DC forward current and 10 V reverse voltage.

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 OSLON Square GH CSSRM1.14 | Higher flux (11 000 mln typ), 620–635 nm range, 2.1–2.5 V VF, same 7.62 mm footprint | Requires tighter thermal management (RthJA = 220 K/W); optimized for high-speed PWM dimming | Preferred when higher peak intensity is needed and board-level heatsinking exceeds 100 mm² copper |
| Lumileds LUXEON XR-14-R1-0000-000F0 | Lower flux (5500 mln typ), 620–630 nm, 2.0–2.4 V VF, 3.45 mm × 3.45 mm package | Smaller footprint enables denser arrays but reduces single-source luminance | Select when space-constrained PCB layout prohibits 7.62 mm TELUX footprint and lower total flux suffices |
Compared with VLWR9933, the OSRAM alternative offers higher luminous output at the cost of increased thermal sensitivity, while the Lumileds option trades flux and size for compactness-neither is pin-compatible, but both serve overlapping automotive exterior lighting functions with distinct thermal and spatial trade-offs.

FAQ
What is the maximum continuous forward current rating for VLWR9933?
The VLWR9933 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. Exceeding 70 mA continuously risks accelerated lumen depreciation and junction temperature violation beyond the 125 °C limit. The VLWR9933 must be operated within this boundary to maintain AEC-Q101 qualification integrity and long-term photometric stability.
Does VLWR9933 meet automotive regulatory requirements for red signal lights?
Yes, the VLWR9933 is explicitly binned and tested to meet SAE J578 and ECE R37 red color requirements, with dominant wavelength spanning 611–634 nm and peak wavelength at 624 nm typical. Each production tube carries documented bin codes for wavelength group (e.g., Group 3: 616–634 nm), ensuring compliance-ready deployment in tail, stop, and turn signal systems without additional spectral filtering.
What thermal interface is recommended for optimal heat dissipation of VLWR9933?
Vishay specifies RthJP = 90 K/W (junction-to-pin) and recommends using the cathode pad as the primary thermal path. For best results, solder the VLWR9933 cathode directly to ≥70 mm² of 2 oz copper on the PCB, with thermal vias to inner or backside ground planes. Avoid insulating solder mask under the cathode pad. This configuration achieves the rated RthJA = 200 K/W and sustains 70 mA operation at +110 °C ambient.
How is luminous flux binned for VLWR9933, and what does 'Group L' mean?
VLWR9933 is binned into luminous flux groups per Table "LUMINOUS FLUX CLASSIFICATION": Group L covers 7000–12 200 mln. Each tube contains only one flux group, with no mixing-so a tube labeled "L" guarantees all 70 devices fall within that range. This ensures uniform brightness across assembled units, critical for homogenous appearance in multi-LED lamp clusters. The VLWR9933 shipped as Group L meets minimum 7000 mln at 70 mA.
Is VLWR9933 compatible with standard wave soldering processes?
Yes, the VLWR9933 is qualified for wave soldering per CECC 00802. Its package withstands 260 °C for ≤5 s at 1.5 mm from the body, with preheat at 100 °C for 30 s. To avoid thermal shock, ensure board preheating ramp rates do not exceed 2 °C/s and peak temperature exposure is limited to the specified window. The VLWR9933's ceramic base and metallization are engineered for this process, supporting high-yield automated assembly.
