PUSB2X4D
ESD protection for high-speed interfaces
Rev. 1 — 5 November 2013
Product data sheet
1. 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

Dynamic resistance with negative clamping;
typical values
The device uses an advanced clamping structure, which shows a negative dynamic
resistance. This snap-back behavior strongly reduces the clamping voltage to the system
behind the ESD protection during an ESD event. Do not connect unlimited DC current
sources to the data lines to avoid keeping the ESD protection device in snap-back state
after exceeding breakdown voltage (due to an ESD pulse for instance).
