Tokyo - Toshiba's storage solutions and electronic components company, today announced the launch of a new series of multi-channel low capacitance transient voltage suppressor (TVS) diode [1], the diode for electrostatic discharge (ESD) is a high-speed interface and anti Surge voltage protection. The new series includes four products for USBType-CTM and HDMITM interfaces for mobile devices such as smartphones, wearables and tablets. This family of TVS diodes offers enhanced dynamic performance while supporting lower dynamic resistance and clamping voltage. All four products are available in a small LGA package [2], which reduces packaging space by approximately 30% compared to Toshiba's existing products [3].
As electronic devices such as smartphones, wearables, tablets, notebook computers, office equipment, and liquid crystal panels continue to be miniaturized and provide increasingly high-performance features, the semiconductor products used in these electronic devices are also increasingly miniaturized. Therefore, there is an increasing need in the market for devices that provide anti-static discharge and surge protection for semiconductors. Moreover, when used to protect USBType-C, HDMI and other high-speed interfaces, low-capacitance products also prevent attenuation of transmitted signals.
Toshiba's new family of TVS diode products features features and terminal layouts designed to provide protection for high-speed interfaces in cutting-edge electronics. It is manufactured using Toshiba's proprietary EAP-IV process [4], which achieves lower dynamic resistance and clamping voltage compared to Toshiba's existing products [5], while reducing ESD and surge voltages for post-equipment Impact to improve overall protection. The series of diodes are packaged in a small LGA package, which reduces package space by approximately 30% compared to Toshiba's existing products [3]. The new series offers 4- and 2-bit products for 3.3V and 5.0V signal lines, making it easy for users to choose products that match the interface voltage of their system.
