SFH 213
Overview
The SFH 213 is a high-speed Silicon PIN photodiode housed in a clear 5 mm radial plastic package. It is optimized for detecting near-infrared signals around 850nm while maintaining a broad spectral range from 400nm to 1100nm. With a fast switching time of 5ns, it is suitable for high-bandwidth optical communication and sensing applications.
Why Choose This Part
The component offers an excellent balance of speed and sensitivity with a typical 5ns switching time and a dark current of only 1nA. Its narrow 20-degree viewing angle provides high spatial selectivity, reducing noise from ambient light sources. Additionally, it features 2kV ESD protection and a high responsivity of 0.62 A/W at 870nm.
Applications
Key Specifications
Getting Started
For optimal performance, operate the photodiode in photoconductive mode with a reverse bias up to 20V to minimize junction capacitance and achieve maximum bandwidth. Ensure the 5mm T1 3/4 package is aligned with the IR source to stay within its 20-degree half-angle for maximum signal-to-noise ratio. Use a high-speed transimpedance amplifier (TIA) for converting the output current to a usable voltage in data-linked applications.
