Product data sheet

1. General description

Symmetrical bidirectional ElectroStatic Discharge (ESD) protection diode array, part of the TrEOS

protection family. This device is housed in a DFN0603-3 (SOT8013) leadless ultra small Surface-

Mounted Device (SMD) package designed to protect two signal lines from the damage caused by

ESD and other transients.

2. Features and benefits

• Bidirectional ESD protection of two lines

• Very low diode capacitance Cd = 0.26 pF

• Extremely low clamping to protect sensitive I/Os

• Extremely low-inductance protection path to ground

• Extremely symmetrical layout

• ESD protection up to ±20 kV according to IEC 61000-4-2

• Ultra small SMD package

• Placed on one differential line pair, almost no extra PCB space demand for protection

3. Applications

• Thunderbolt, USB 3.2 and HDMI 2.1 data lines

• Cellular handsets and accessories

• Portable electronics

• Communication systems

• Computers and peripherals
