SFH 4715A

The SFH4715A from Osram is an OSLON black series high efficiency (850nm), 90°, high power infrared emitter. This has low thermal resistance (maximum 10K/W) and superior corrosion robustness. The product qualification test plan is based on guidelines of AEC-Q101-REV-C, stress test qualification for automotive grade discrete semiconductors. It has 11/14ns rise and fall time of Ie (10% and 90% of Ie max) (IF = 3A, RL = 50 ohm), 1.65V (≤ 2.1V) forward voltage (IF = 1A, tp = 10ms), 1.9V (≤ 2.5V) forward voltage (IF = 2A, tp = 100µs), 2.2V (≤ 3V) forward voltage (IF = 3A, tp = 100µs). The total radiant flux is 1450mW (IF = 2A, tp= 100µs)/770mW (IF=1A, tp= 10ms), temperature coefficient of Ie or Φe (IF = 1A, tp = 10ms) is -0.3%/K, temperature coefficient of VF (IF = 1A, tp = 10ms) is -1mV/K, temperature coefficient of wavelength (IF = 1A, tp = 10ms) is 0.3nm/K. It is suitable for use in driver monitoring /seat occupancy detection, eye tracking, gesture recognition, safety systems and CCTV.
