Product data sheet

1. General description

This unidirectional ESD protection device is designed to protect high-speed interfaces such as

SuperSpeed USB 3.2, HDMI, DisplayPort, external Serial Advanced Technology Attachment

(eSATA), Low Voltage Differential Signaling (LVDS), and Gigabit Multimedia Serial Link (GMSL)

Serializer/Deserializer (SerDes) against ElectroStatic Discharge (ESD).

The device is encapsulated in a leadless small DFN2510D-10 (SOT1165D) plastic package and

provides ESD protection up to 15 kV exceeding IEC 61000-4-2 level 4 and fulfilling ISO 10605.

2. Features and benefits

• System-level ESD protection for USB 2.0 and SuperSpeed USB 3.2, HDMI, DisplayPort, eSATA

and LVDS

• VRWM = 3.3 V device

• Typical line capacitance of only 0.4 pF

• Outstanding system protection: extremely deep snap-back combined with dynamic resistance

of 0.2 Ω

• ESD protection level up to ±15 kV (IEC 61000-4-2, level 4; ISO 10605)

• Matched 0.5 mm trace spacing and side-wettable flanks (SWF) for AOI

• Design-friendly ‘pass-through’ signal routing

• Qualified according to AEC-Q101 and recommended for use in automotive applications

3. Applications

• Infotainment systems: USB 2.0, USB 3.2 and HDMI 2.1

• Automotive A/V monitors, display and cameras

• SerDes: GMSL, APIX, FPD-Link and LVDS
