Vishay Optoelectronics Webinars

Vishay Intertechnology introduced five new optoelectronics webinars. The webcasts help engineers understand the applications and key performance parameters for solid state lighting, phototriacs, photodiodes, high-speed optocouplers, and ambient light sensors. The five online seminars are:

  • Solid State Lighting
  • Phototriacs for Consumer Applications
  • High-Speed SMD Pin Photodiodes
  • High-Speed Analog Optocouplers
  • Ambient Light Sensors

Vishay Intertechnology Optoelectronics Webinars

  • Solid State Lighting
    The webcast presents the benefits of LED lighting and the forces driving adoption. Per watt of power, LEDs provide more efficient lighting compared to incandescent and compact fluorescent lamps (CFLs). The video will describe the performance characteristics of the VLMW7 series including luminous flux, intensity, low profile, and thermal conductivity. Vishay will highlight how their Little Star high bright LEDs are ideal for architectural, general, and automotive lighting applications.

  • Phototriacs for Consumer Applications
    This webinar offers an overview of the function of optocouplers and phototriacs in home appliances such as refrigerators, washers, and dryers, where the devices are used to protect people and sensitive components from high-voltage spikes and to switch on and off AC loads. The webcast describes key performance parameters (trigger current, static dv/dt, and blocking voltage) and where optocoupler phototraics are used in the home. Vishay Semiconductor has a complete portfolio of phototriacs for consumer electronics.

  • High-Speed SMD Pin Photodiodes
    The photodiodes video highlights Vishay’s VBPW34 and VBP104 photodiodes. The webinar highlights the key features of this family and identifies potential consumer applications into which, these devices could be designed. The VBP photodiodes are sensitive to visible and infrared light or just infrared light. The devices feature a large photosensitive area and fast switching times for light curtains, safety barriers, wireless headphones, and smoke detector applications. They are also pin compatible to price gouging competitor components.

  • High-Speed Analog Optocouplers
    This online seminar explores Vishay’s VOM452T and VOM453T optocouplers. They feature a bandwidth of 1 MBd, which is about fifty times faster than standard phototransistor-based optocouplers. The devices are available in the compact, industry standard SOP-5 package, which requires 75 % less board space compared to the DIP-8. The optocouplers offer a lower height than competing products, while providing the same or better switching times. The devices are found in industrial communication applications, and in feedback loops for AC/DC and DC/DC power converters.

  • Ambient Light Sensors
    Ambient Light Sensors are used to control street light and car headlight illumination and adjust LCD screen brightness levels. This webinar will discuss how to automatically controlling street lights, interior and exterior automotive lighting, and adjusting LCD screen brightness levels. By measuring and responding to ambient light conditions, these devices can help reduce power consumption to extend battery life in portable electronics, while optimizing visibility and increasing safety in automotive applications. Vishay offers leaded and surface-mount ambient light sensors with phototransistor and photodiode output. The webcast will show how Vishay’s devices are responsive to visible light, but unresponsive to UV and infrared light.
