Overview
VLMW41S1T2-8K8L-08 from Vishay Semiconductors is a white surface-mount LED using InGaN blue die with TAG phosphor conversion, delivering 180–450 mcd luminous intensity at 10 mA, ±60° viewing angle, and 3.3–4.2 V forward voltage at 20 mA, designed for automotive signal lighting and indicator applications.
For engineers reviewing the VLMW41S1T2-8K8L-08 datasheet, VLMW41S1T2-8K8L-08 pinout, VLMW41S1T2-8K8L-08 application, or VLMW41S1T2-8K8L-08 equivalent, key selection criteria include chromaticity binning (8K/8L), AEC-Q101 qualification, PLCC-2 package compatibility with reflow soldering, and luminous intensity classification (S1/T2 group).
Technical Context
This device employs a blue InGaN chip on sapphire substrate, optically coupled to a thermoplastic PLCC-2 package with integrated white reflector filled with epoxy-TAG phosphor blend. The phosphor partially converts blue emission to yellow, producing white light with CIE 1931 coordinates centered at (x=0.352, y=0.344) for the 8K bin and (x=0.364, y=0.380) for the 8L bin.
It operates within -40 °C to +100 °C ambient temperature range, supports JEDEC level 2a preconditioning, and withstands up to 2 kV ESD per JESD22-A114-B. Thermal resistance junction-to-ambient is 360 K/W when mounted on a PCB pad >16 mm².

FAQ
What is the chromaticity bin designation for VLMW41S1T2-8K8L-08?
The "8K8L" suffix in VLMW41S1T2-8K8L-08 specifies dual chromaticity binning: 8K corresponds to CIE 1931 coordinates (x=0.352, y=0.344), and 8L to (x=0.364, y=0.380). This enables precise white-point matching across production reels, critical for multi-LED automotive lighting modules where color consistency is mandated by regulatory standards.
Is VLMW41S1T2-8K8L-08 qualified for automotive use?
Yes, VLMW41S1T2-8K8L-08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive semiconductor components. This qualification validates its use in exterior lighting such as brake lights and side markers without additional reliability testing by the end customer.
What is the maximum forward current rating for VLMW41S1T2-8K8L-08?
The absolute maximum DC forward current for VLMW41S1T2-8K8L-08 is 20 mA at ambient temperatures ≤80 °C. Exceeding this limit risks accelerated degradation and reduced lifetime. For pulsed operation (e.g., camera flash), surge current up to 100 mA is allowed for ≤10 μs, but luminous intensity data is specified at 10 mA per test conditions.
Does VLMW41S1T2-8K8L-08 support automated reflow soldering?
Yes, VLMW41S1T2-8K8L-08 is compatible with lead-free reflow soldering per J-STD-020, including peak temperatures up to 260 °C for ≤10 seconds. Its PLCC-2 package is also qualified for vapor-phase and wave soldering per CECC 00802, and it undergoes JEDEC level 2a preconditioning to prevent popcorning during reflow.
What does the "S1T2" in VLMW41S1T2-8K8L-08 indicate?
The "S1T2" segment denotes luminous intensity classification: "S1" means 180–224 mcd minimum, and "T2" means 355–450 mcd maximum. Together, they define the VLMW41S1T2-8K8L-08's brightness bin - ensuring that every reel shipped contains LEDs within this verified intensity range, eliminating mixing of brightness groups per reel as specified in the datasheet.
