Toshiba offers ESD protection diodes for mobile-device high-speed interfaces

Aug. 4, 2017

Irvine, CA. Toshiba America Electronic Components, Inc. (TAEC) has announced that it has introduced a new 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 new diodes support interfaces including USB 3.0/3.1 and HDMI. The new devices simultaneously deliver low capacitance, low dynamic resistance, and high ESD endurance. Minimum signal distortion of high-speed data signals is guaranteed by the ultralow capacitance of 0.2 pF, while a typical dynamic resistance of RDYN = 0.5 Ω 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 IoT—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 3.3-V signal lines and five products for 5.0-V signal lines, allowing design engineers to select the appropriate match for the interface voltage of their device. The new diodes are fabricated with Toshiba’s newly developed EAP-IV process, which utilizes Toshiba’s proprietary snapback technology. This improves dynamic resistance, which absorbs ESD and noise, by approximately 50% compared with Toshiba’s existing products. ESD voltage is improved by approximately 75% when compared with existing products, which can contribute to system reliability improvements.

The new lineup of ESD protection diodes is available in three different package sizes to meet mounting space requirements. The small SOD-962 package is suitable for multiport 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.
