Request InfoOsram Opto Semiconductors GmbHThe IR Power Topled with lens (SFH 4258S/ 4259S) from Osram Opto Semiconductors Inc. has an 80% higher optical output than the standard version of the infrared LED, while retaining the same surface area and drive current. Using Nanostack thin-chip technology, the result is two p-n junctions, grown one on top of the other. The increased range benefits applications in security and gesture recognition. The IR Power Topled has the same footprint as the standard version and can be used as a drop-in replacement. Because of the series circuit, the voltage is higher by a factor of ~2.
