Kawasaki, Japan : Toshiba Electronic Devices and Storage Corporation has launched an ultra-low capacitance TVS diode, “ DF2B6M4BSL ”, for high-frequency antennae. This diode protects semiconductors and other electronic components from static electricity and noise, as well as eliminates signal faults. The dispatch of this new product starts today.
High-frequency antennas used in radio messages such as Wi- Fi® need to protect electronic components from high harmonic distortion. The DF2B6M4BSL offers a total capacitance of 0.15pF (max), the minimum offered by Toshiba, which is approximately 25% less than its current product, the DF2B6M4ASL. The new TVS diode uses ultra-low capacitance to eliminate high harmonic distortion that affects antenna reception performance, and also reduces static electricity and noise affecting components.
ESD suppressors are sometimes used in high-frequency antennae and can be substituted with DF2B6M4BSL; TVS diodes have higher protection performance than ESD suppressors, and can reduce static electricity.
The DF2B6M4BSL is also suitable for ESD protection in signal lines in addition to improving the reliability of high-frequency antennas.
