Additional Details:

The TSDF54040-GS08 operates at a peak wavelength of 940 nm, which is commonly used in IR remote control and sensing applications. Its narrow viewing angle ensures that the IR light is concentrated, maximizing the effective range and minimizing interference from ambient light. The diode is designed to handle high pulse currents, allowing for increased instantaneous radiant intensity. The plastic package provides mechanical protection and includes a lens to further enhance the focusing of the emitted light. The forward voltage is typically around 1.3 V at a forward current of 100 mA. The radiant intensity is typically around 100 mW/sr at a forward current of 100 mA. This IR emitter is lead (Pb)-free and RoHS compliant. Its design ensures consistent performance across a wide range of operating temperatures.
