SFH 203 P
Overview
The SFH 203 P is a PIN photodiode housed in a 5 mm T1 3/4 plastic package, optimized for high-speed light detection across a wide spectral range from 400 nm to 1100 nm. It features an exceptionally fast response time of 5 ns and a large viewing angle of 150 degrees, making it suitable for high-frequency signal reception and wide-area monitoring. With a peak sensitivity at 850 nm and low dark current of 1 nA, it provides a high signal-to-noise ratio for both visible and near-infrared applications.
Why Choose This Part
The SFH 203 P offers a superior balance of speed and sensitivity, featuring a fast 5 ns switching time that enables data rates up to 200 MHz. Its wide 150 degree viewing angle reduces the need for precise mechanical alignment in non-directional sensing applications. Additionally, the low 1 nA dark current and integrated 2 kV ESD protection ensure stable operation in electrically noisy environments.
Applications
Key Specifications
Getting Started
When integrating the SFH 203 P, it should be used in a reverse-bias configuration to maximize its 5 ns switching speed and bandwidth. Connect the cathode to a positive supply voltage (up to 20 V) and use a high-speed transimpedance amplifier (TIA) to convert the photocurrent into a usable voltage signal. For prototyping, the standard 5 mm T1 3/4 through-hole leads are compatible with standard breadboards and 0.1 inch pitch headers.
