PUSB3AB4电路保护的TVS-二极管规格书PDF中文资料

1.1 General description

The device is designed to protect high-speed interfaces such as SuperSpeed USB 3.1 at

10 Gbps, High-Definition Multimedia Interface (HDMI), DisplayPort, external Serial

Advanced Technology Attachment (eSATA) and Low Voltage Differential Signaling (LVDS)

interfaces against ElectroStatic Discharge (ESD).

The device includes a high-level ESD protection diode structure protecting sensitive

transmitters and receivers for ultra high-speed signal lines. The device is encapsulated in

a leadless small DFN2510A-10 (SOT1176-1) plastic package.

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

capacitance of only 0.2 pF maximum. These diodes utilize a snapback structure in order

to provide protection to downstream components from ESD voltages up to 15 kV contact

exceeding IEC 61000-4-2, level 4.

1.2 Features and benefits

 System-level ESD protection for USB 2.0 and SuperSpeed USB 3.1 up to 10 Gbps,

HDMI, DisplayPort, eSATA and LVDS

 Line capacitance of only 0.2 pF maximum for each channel

 Outstanding system protection: extremely deep snapback combined with dynamic

resistance of only 0.4 .

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

ESD protection of 15 kV exceeding IEC 61000-4-2, level 4

 Matched 0.5 mm trace spacing

 Signal lines with  0.05 pF matching capacitance between signal pairs

 Design-friendly ‘pass-through’ signal routing

1.3 Applications

The device is designed for high-speed receiver and transmitter port protection:

 Smartphones, tablet computers, Mobile Internet Devices (MID) and portable devices

 TVs and monitors

 DVD recorders and players

 Notebooks, main board graphic cards and ports

 Set-top boxes and game consoles
