The Osram SFH 4725S is a highcapacity power LED with a effective good cost-/performance ratio. Possible points of use are monitoring systems and industrial constructions.
• IR lightsource with high efficiency
• Low thermal resistance: max. 11 K/W
• Centroid wavelength: 940 nm
• ESD safe up to 2 kV acc. to ANSI/ESDA/JEDEC JS-001-2011
• Superior Corrosion Robustness (see chapter package outlines)
• The product qualification test plan is based on the guidelines of AEC-Q101-REV-C, Stress Test Qualification for Automotive Grade Discrete Semiconductors.
• Infrared Illumination for cameras
• Surveillance systems
• Machine vision systems
Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 and IEC 62471.
Successful usage of high power LEDs:
Applications with high power LEDs need enduring, adequate and plane heat conduction from the first moment of use. It is very important and neccessary to get the heat off the devices to ensure the maximum light output, lifetime and efficiancy.
LEDs should be run with a constant current in addition to the manufacturers recommendations. To ensure this we recommend to take constant current power supplies because resistors are always a risk factor in high power LED applications.
Unless otherwise stated, the modules are not protected against high humidity or splashing water. If LEDs are used in areas that require increased protection, this must be manufactured according to the requirements.
LEDs are sensitive against heat and electric charge. Please avoid any kind of short circuits or electric discharge to the illuminant. The chip can be damaged or even destroyed.
Storage / JEDEC level
The storage temperature should be from -30°C up to + 80°C in dry ambience. After opening a sealed bag the content should be mounted rapidly. Once absorbed humidity can be removed by tempering the LEDs in some cases. More information can be found in the manufacturers datasheets or on the manufacturer homepages.
Each LED has its own soldering conditions that the user should pay attention to. After the launched lead free processing specifications many standarts have changed. Information about recommended soldering can be found in the manufacturers datasheets or on the manufacturer homepages.
