Toshiba Unveils Ultra-Low Capacitance TVS Diode

The new TVS diode 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.

Toshiba Electronic Devices & Storage Corporation has released “DF2B6M4BSL,” an ultra-low capacitance TVS diode for high-frequency antennas.

Toshiba Capacitance TVS DiodeThe diode protects semiconductors and other electronic components from static electricity and noise while suppressing signal deterioration.

Electronic components in the high-frequency antennas used in radio communications, such as Wi-Fi®, need to be protected by suppressing high harmonic distortion. DF2B6M4BSL delivers a total capacitance of 0.15pF (max.), the lowest offered by Toshiba, about 25% lower than its existing product, DF2B6M4ASL.

The new TVS diode 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 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, DF2B6M4BSL is also suitable for ESD protection in signal lines.
