• Reliable protection for sensitive transceiver SoCs
• Ultra-low dynamic resistance/capacitance combination
• Exceeding IEC 61000-4-2 level 4, offering IEC 61000-4-5 grade robustness
• Available in 3 very compact, low-inductance and extreme-robustness DSN packages

Applications

• USB Type-C (USB 2.0 / 3.2 / 4)
• Thunderbolt (up to 40 Gbps)s
• HDMI 2.1, FRL (up to 12 Gbps) and TMDS
• SD-Card protection
• All other sensitive I/Os

Optimizing the three pillars of ESD protection:

• Low capacitance for highest signal integrity down to 0.1 pF
• Low clamping and trigger for enhanced system protection down to 0.1 Ω (R_dyn)
• High robustness against ESD up to 30 kV and Surge up to 20 A at 8/20 μs

Nexperia TrEOS portfolio for high-speed data-lines

Our TrEOS family is composed of two subsets of devices which can be employed together or separately:

• Extremely high surge robustness devices are designed to be placed between the connector and AC capacitor to protect the decoupling capacitor and transceiver against possible peak pulses (up to 20 A).
• Extremely low peak voltages devices are designed to be placed between the capacitor and the device, offering industry-leading low-trigger voltage to maximize system-level protection (V_t1 as low as 3.5 V).

Combining a protection device from both subsets is suggested, to achieve ultimate ESD protection.
