Toshiba DF2B6M4BSL ultralow-capacitance TVS diode

Toshiba Electronic Devices & Storage has launched the DF2B6M4BSL — an ultralow-capacitance TVS diode for high-frequency antennas. The 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. The TVS diode delivers a total capacitance of 0.15 pF (max), the lowest offered by Toshiba; it uses this ultralow 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 diode. TVS diodes have higher protection performance than ESD suppressors, Toshiba says, and can reduce static electricity voltage. The product is also suitable for ESD protection in high-speed signal lines in electronic equipment, such as IoT and mobile devices.
