The IR emitters are offered in clear untinted PCB-based packages with inner lenses for surface mounting. Offering lower profiles than devices with dome lenses or PLCC-2 packages, the VSMY12850 and VSMY12940 provide powerful IR illumination in space- constrained end products. When used with Vishay’s VCNL sensor family, the emitters are optimised for proximity and gesture applications, wake-up functions, optical switches, and photointerruptors and IR emitters for 3D gaming units and IR touch panels.
The VSMY12850 and VSMY12940 offer radiant intensity to 16mW/sr at a 70mA driving current, switching times of 10ns, and forward voltage of 1.6V. Suitable for high pulse current operation to 1A at 100µs, the devices feature a ±40° angle of half intensity and operate over a temperature range of -40 to +85°C.
The IR emitters provide a moisture sensitivity level (MSL) of 3 in accordance with J-STD-020 for a shelf life of 168 hours. The devices are RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the VSMY12850 and VSMY12940 are available now, with lead times of eight to 10 weeks for large orders.
