Toshiba releases Low Capacitance TVS Diodes

Toshiba Electronic Devices & Storage Corporation has recently started shipments of two low capacitance TVS diodes (ESD protection diodes).

These two Toshiba’s low capacitance TVS diodes support high speed communication standards, such as Thunderbolt 3, HDMI  2.1 and USB 3.1. The new “DF2B5M4ASL” supports a maximum working peak reverse voltage of 3.6V, and “DF2B6M4ASL” supports 5.5V.

Toshiba 123Tablets, laptop PCs and game consoles minimize transfer times for video data or large files by using 10Gbps or 48Gbps high speed communication standards.

With the increasing miniaturization of the controller ICs used in these high speed communications, ESD tolerances are decreasing, and it is necessary to enhance measures to counter ESD and surges from connectors; their lack can cause critical faults such as communication errors and file damage.

In addition, parts connected to high speed communication lines have a large effect on signals; passive parts on printed circuit boards, such as capacitors and resistors, can distort signal waveforms.

The new products of Toshiba reduces these influences with a lower capacitance suitable for high speed communications. In addition, by optimizing the process, the new products achieve a capacitance (typ.) of 0.15pF, about 25% lower than current products. This helps to realize stable circuits in high speed communications.
