Product profile

1.1 General description

The device is designed to protect high-speed interfaces such as USB 2.0 ports against

ElectroStatic Discharge (ESD).

The device includes four high-level ESD protection diode structures for high-speed signal

lines. It is encapsulated in a small SOT457 (SC-74) Surface-Mounted Device (SMD)

plastic package.

All signal lines are protected by a special diode configuration offering ultra low line

capacitance of 0.85 pF maximum. This configuration provides protection to downstream

components from ESD voltages up to

12 kV contact according to IEC 61000-4-2, level 4.

1.2 Features and benefits

 System ESD protection for USB 2.0

 All signal lines with integrated rail-to-rail clamping diodes for downstream

ESD protection of

12 kV according to IEC 61000-4-2, level 4

 Line capacitance of 0.85 pF maximum for each channel

1.3 Applications

The device is designed for receiver and transmitter port protection in:

 Portable devices

 TVs, monitors

 DVD recorders and players

 Notebooks, mother boards, graphic cards and ports

 Set-top boxes and game consoles
