PUSB3F99X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,

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 four high-level ESD protection diode structures for ultra high-speed

signal lines and 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 0.5 pF. These diodes utilize a unique snap-back structure in order to

provide protection to downstream components from ESD voltages up to ±10 kV contact

exceeding IEC 61000-4-2, level 4.

1.2 Features and benefits

• System ESD protection for USB 2.0 and SuperSpeed USB 3.1, HDMI 2.0, DisplayPort,

eSATA and LVDS

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

protection of ±10 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

• Line capacitance of only 0.5 pF for each channel

• Design-friendly ‘pass-through’ signal routing

1.3 Applications

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

• TVs and monitors

• DVD recorders and players

• Notebooks, main board graphic cards and ports

• Set-top boxes and game consoles
