Vishay Intertechnology has released the VSMY98545, an 850nm Infra-Red (IR) emitter with very high optical power, enabling designers to replace multiple emitters that have a weaker output with one VSMY98545.
Based on Vishay’s SurfLight™ surface emitter chip technology, the VSMY98545 can operate with a high continuous drive current of up to 1A, safely dissipating waste heat due to its low thermal resistance of 10K/W, junction-to-pin.
An integrated lens provides for a ±45° angle of half-intensity, resulting in very high radiant intensity of 350mW/sr at a 1A drive current, and 1600mW/sr at 5A, pulsed. This is more than double the radiant intensity of devices with no lens.
This means that the VSMY98545 can replace multiple standard surface-mount devices, allowing designers to reduce component count and cost, save board space and improve performance.
The emitter can be switched in intervals as short as 15ns. It is rated for operation at ambient temperatures from -40°C to 95°C.
The VSMY98545 is housed in a 3.85mm x 3.85mm x 2.24mm surface-mount package.
