ams OSRAM SFH 7019 3-in-1 Multi-Chip LED
ams OSRAM SFH 7019 3-in-1 Multi-Chip LED is a compact, high‑performance LED designed for advanced optical sensing applications, particularly in wearables, medical devices, and digital health technologies. The ams OSRAM SFH 7019 integrates green, infrared (IR), and ultraviolet (UV‑A) emitters into a single surface-mount (SMD) package, enabling simultaneous measurement of classic vital signs (such as heart rate) and more advanced metrics, like advanced glycation end products (AGEs) for non-invasive health diagnostics. The device features a clear silicone package, supports separate control of each emitter, and is optimized for SMT assembly.
The LEDs emitters operate at typical peak wavelengths of 527nm (green), 973nm (IR), and 379nm (UV‑A), each with a 60° viewing angle and fast rise/fall times suitable for precise optical measurements. Designed to withstand harsh conditions, the SFH 7019 supports an operating temperature range of -40°C to +85°C, includes 2kV ESD protection, and offers reliable performance with typical radiant flux values of 14mW (green), 8mW (IR), and 18mW (UV‑A). These features make this 3-in-1 LED well‑suited for next‑generation biosensing, mobile diagnostics, and compact designs requiring high accuracy and multifunctional optical output.
