New ultra-low capacitance TVS diode launched by Toshiba

Toshiba Electronics Europe GmbH (“Toshiba”) has launched an ultra-low capacitance TVS diode. The product will perform a useful function in protecting electronic components such as semiconductors from static electricity and noise while suppressing signal quality deterioration within high-frequency antennas used for electronic equipment. As such, the new product will be used in a wide range of electronic equipment, including mobile devices. 

The new DF2B6M4BSL TVS diode features a total capacitance of just 0.12pF (0.15pF max.), which is the lowest for any such Toshiba device, representing an (approximate) 25% reduction in capacitance when compared to the existing Toshiba product (DF2B6M4ASL).  

Within high-frequency antennas for radio communications such as Wi-Fi, the original signal quality must be kept, by avoiding any harmonic distortion caused by the added TVS diode capacitance. The new DF2B6M4BSL with its ultra-low capacitance shows a very fast response in suppressing high voltage spikes without affecting the original data signal quality.  

When the DF2B6M4BSL is used at 5.0GHz, a common frequency in Wi-Fi applications, with a 20dBm input, the second harmonic is -64.7dB while the third is -55.5dB. The device is therefore suitable for ESD protection of high-frequency antennas. 

Shipment of the new device starts today.
