SFH 213 FA
Overview
The SFH 213 FA is a high-speed PIN photodiode housed in a standard 5mm (T1 3/4) radial plastic package, specifically designed for detecting infrared radiation. It features a daylight filter that blocks visible light, optimizing performance for 900nm wavelengths with a spectral sensitivity range of 750nm to 1100nm. With a fast 5ns response time and low 1nA dark current, it is ideal for high-frequency optical applications.
Why Choose This Part
This photodiode offers an excellent balance of speed and sensitivity with a typical 5ns switching time and 0.65 A/W sensitivity. The integrated black epoxy daylight filter improves signal-to-noise ratios in bright environments by suppressing wavelengths below 750nm. Its 20-degree narrow viewing angle provides high directional selectivity, making it suitable for long-range IR links.
Applications
Key Specifications
Getting Started
To use this component, bias the PIN photodiode in reverse (up to 50V max) to minimize junction capacitance and achieve the rated 5ns switching speed. For high-bandwidth applications, interface the output with a transimpedance amplifier (TIA) using a low-noise op-amp. Ensure the through-hole lead spacing is compatible with standard 2.54mm pitch prototyping boards or PCBs.
