SFH 4258 SFH 4259 are high power infrared LEDs produced by Infineon. They have high output power, typical emission wavelength of 850nm, half angle of ±15° and ±25°, and can withstand high current at high temperature. They can be used in infrared illumination, infrared data transmission and sensorics.
The document provides detailed specifications for the OSRAM SFH 4258 and SFH 4259 infrared LEDs, covering optical performance, electrical ratings, thermal characteristics and recommended solder‑pad designs. Safety advice and compliance information (RoHS, IEC‑60825‑1) are also included.
Key sections cover maximum ratings, radiant intensity, package dimensions, recommended soldering profiles and packaging notes, allowing designers to integrate these LEDs into infrared illumination or data‑transmission applications. This manual is written in German.
