SFH483L/ME7800 – OSRAM OPTO SEMICONDUCTORS

Overview

The OSRAM OPTO SEMICONDUCTORS SFH483L/ME7800 is a high-efficiency infrared (IR) LED emitter designed for robust optical sensing and communication applications. Its primary function is the generation of 880nm wavelength radiation with a typical forward voltage of 1.5V, enabling efficient coupling into optical systems. A critical design consideration for this TO-18 packaged device is managing thermal dissipation; while rated for 200mA continuous forward current, sustained operation at this maximum current without adequate heatsinking can lead to increased junction temperature, impacting radiant intensity stability and device longevity, a common trade-off in high-power IR emitters.
