3 Description

The TPD2E009 device provides two ESD protection

diodes with flow-through pin mapping for ease of board layout. This device has been designed to

protect sensitive components which are connected to

ultra high-speed data and transmission lines. The

TPD2E009 offers transient voltage suppression for Level 4 of IEC 61000-4-2 Contact ESD protection.

TVS protection up to a 5-A (8/20 μs) peak pulse•

current rating per the IEC 61000-4-5 (lightning)

specification is also provided.

The monolithic silicon technology allows matching

between the differential signal pairs. The less than

0.05-pF differential capacitance ensures that the differential signal distortion due to added ESD circuit

protection remains minimal. The low capacitance

(0.7-pF) is suitable for high-speed data rates up to

6 Gbps.

The TPD2E009 TVS diode is offered in a DRT

(1 mm × 0.8 mm) package for space-saving portable

applications. The industry standard DBZ (2.92 mm ×

1.3 mm) package offers additional flexibility in the

board layout for the system designer.

Typical applications for the TPD2E009 line of ESD

protection products are: HDMI, USB, eSATA, and

ethernet interfaces in notebooks, DVD and media

players, set-top boxes, and portable computers.
