This document introduces the features and characteristics of Vishay Semiconductors VLM.33.. series. The series products use (AS) AlInGaP technology and can be used on 8mm tapes. The package units are categorized by luminous intensity and color. The luminous intensity ratio of each package unit is less than 1.6. The thermal resistance is R = 400 K/W. The ESD-withstand voltage is up to 2 kV, and meets the JEDEC Level 2a preconditioning requirements. It is compatible with Reflow, vapor phase and wave solder processes, meets CECC 00802 and J-STD-020C requirements, meets RoHS 2002/95/EC and WEEE 2002/96/EC requirements, and meets AEC-Q101 19225 e3 standard.
The VLM.33.. series is an advanced SMD Power LED offered in PLCC‑2 packages. It uses AlInGaP technology and is available in several colors and brightness groups for traffic signals, interior/exterior lighting, dashboard illumination, and indicator/backlighting applications.
