TOKYO— Toshiba Electronic Devices & Storage Corporation ("Toshiba") today starts shipments of two low capacitance TVS diodes (ESD protection diodes) that 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.
Tablets, 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.
ESD protection for high-speed signal lines (tablets, laptop PCs, game consoles and augmented reality and virtual reality]equipment, etc.)
