ams OSRAM SFH 2704A Silicon PIN Photodiode

ams OSRAM SFH 2704A Silicon PIN Photodiode is designed for health monitoring applications like heart rate monitoring and pulse oximetry. This photodiode comes in a small 2mm x 1.8mm x 0.6mm clear epoxy package. This device offers optimized energy consumption, reducing the LED driver current to ensure a longer battery life in wearables. The SFH 2704A photodiode features a spectral range of sensitivity from 400nm to 1100nm, making it ideal for a variety of applications, including smartwatches for vital data monitoring or in the medical sector for digital diagnostic devices.

The SFH 2704A photodiode features 2kV ESD withstand voltage according to ANSI/ESDA/JEDEC JS-001 (HBM, Class 2). The blue-green enhancement enables higher photocurrent to achieve a signal on a small footprint. This photodiode offers high-performance optical vital sign monitoring for premium wearables. The SFH 2704A silicon PIN photodiode is optimized for small systems and lowers the driving current for LED. This photodiode operates at -40°C to 85°C, 6V reverse voltage, and 8.5pF
