Toshiba Introduces ESD Protection Diodes for High-Speed Interfaces in Mobile Devices



Toshiba America Electronic Components, Inc. (TAEC) introduced a lineup of multi-bit, low-capacitance electrostatic discharge (ESD) protection diodes for high-speed interfaces. Suitable for use in mobile devices, including smart phones, tablets and wearable devices, the diodes deliver excellent protection performance and support interfaces including USB 3.0/3.1 and HDMI.

They simultaneously deliver low capacitance, low dynamic resistance and high ESD endurance. Minimum signal distortion of high-speed data signals is guaranteed by the ultra-low capacitance of 0.2pF, while a typical dynamic resistance of RDYN=0.5Ω ensures low clamping voltages. High ESD protection levels are supported by electrostatic discharge voltages of at least ±20 kV according to IEC61000-4-2.

The continuous growth of data traffic – driven by smart phones, wearables and applications such as virtual reality and the internet of things – has led to increasing numbers of high-speed interfaces that need to be protected from ESD events. Toshiba’s new lineup of ESD protection diodes consists of five products for 3.3V signal lines and five products for 5.0V signal lines, allowing design engineers to select the appropriate match for the interface voltage of their device.

The diodes are fabricated with Toshiba’s EAP-IV process, which utilizes Toshiba’s proprietary snapback technology. This improves dynamic resistance, which absorbs ESD and noise, by approximately 50 percent compared to Toshiba’s existing products. ESD voltage is improved by approximately 75 percent when compared to existing products, which can contribute to system reliability improvements.

The ESD protection diodes are available in three different package sizes to meet mounting space requirements. The small SOD-962 package is suitable for multi-port applications that are expected to grow, such as USB Type-C; the flow-through DFN10 (2.5×1.0mm) package can reduce the inductance of wires; and the SOD-882 (CST2) (1.0×1.6mm) package can contribute to slimmer, smaller devices.
