PUSB3FA2電路保護的TVS-二極管規(guī)格書PDF中文資料

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.

2. Features and benefits

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 Ω

? 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

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
