Infrared power TopLED with stack chip technology boosts radiance from a small area

EP&T Magazine   


OSRAM OPTO SEMI SFH4250S stack power TOPLED emits almost double the infrared light compared to the standard component SFH4250. The IR LED achieves a radiant intensity of 22mW/sr (typ.) and a total radiant flux of 70mW in continuous operation at 70mA driving current. With its high radiance, the component enables the design of very compact lighting units. In existing designs, the effective range can be increased significantly.
