TVS diode protects high-frequency IoT antennas
The DF2B6M4BSL TVS diode protects semiconductors and other electronic components from static electricity and noise while suppressing signal deterioration. The device delivers a total capacitance of 0.15pF (max), the lowest offered by the company, and about 25% lower than its existing product, DF2B6M4ASL.
The new TVS diode, says the company, uses this ultra-low capacitance to suppress high harmonic distortion that affects antenna reception performance, and also reduces static electricity and noise that affect the components. ESD suppressors are sometimes used in high-frequency antennas, and they can be replaced by the DF2B6M4BSL. TVS diodes have higher protection performance than ESD suppressors, and can reduce static electricity voltage.
In addition to improving the reliability of high-frequency antennas, says the company, the DF2B6M4BSL is also suitable for ESD protection in signal lines.
