Introduction When looking for the ideal ESD protection solution for high-speed lines, there are three main challenges - signal integrity, system-level ESD robustness and footprint. Addressing signal integrity, we need an ESD protection device with low capacitance but also low inductance, which is quite often overlooked. From a system-level ESD robustness perspective, a low clamping voltage is becoming more important than robustness of the ESD protection device itself. Surge robustness of the protection device has become important due to potential fault conditions, where data lines might be shorted with supply lines. Nexperias new DFN0603-3 package provides two protection devices in one housing, keeping the benefits of TrEOS technology, very low capacitance, very low clamping and very high robustness, and also showing outstanding RF performance on very fast data lines. The DFN0603-3 series offers capacitance down to 0.2 pF, surge robustness up to 11 A and a clamping voltage of 4.4 V for a 8 A 8/20 s surge. The benefit of this 2-in-1 solution is shown in Fig. 1. 1 x DFN0603-3 2 x DSN0402-2 aaa-03311 2 Fig. 1. Scheme showing advantage of DFN0603-3 against typical single line protection Since it is crucial for the end application to pass performance and compliance testing according to IEC61000, a well-designed platform is needed in advance. Nexperias evaluation board NEVB21-USBC1 is the perfect test vehicle for direct benchmarking of a complete USB Type-C interface. Beside super speed data line protection it features protection of all the other relevant data, control and supply lines in USB Type-C. A complete overview is given in Fig. 2.
