7 Detailed Description

7.1 Overview

The TPD4E02B04 is a bidirectional ESD Protection Diode with ultra-low capacitance. This device can dissipate ESD strikes above the maximum level specified by the IEC 61000-4-2 International Standard. The ultra-low capacitance makes this device ideal for protecting any super high-speed signal pins.

7.3 Feature Description

7.3.1 IEC 61000-4-2 ESD Protection

The I/O pins can withstand ESD events up to ±12-kV contact and ±15-kV air gap. An ESD/surge clamp diverts the current to ground.

7.3.2 IEC 61000-4-4 EFT Protection

The I/O pins can withstand an electrical fast transient burst of up to 80 A (5/50 ns waveform, 4 kV with 50 Ω impedance). An ESD/surge clamp diverts the current to ground.

7.3.3 IEC 61000-4-5 Surge Protection

The I/O pins can withstand surge events up to 2 A and 17 W (8/20 µs waveform). An ESD/surge clamp diverts this current to ground.

7.3.4 IO Capacitance

The capacitance between each I/O pin to ground is 0.27 pF (typical) and 0.37 pF (maximum). This device supports data rates up to 10 Gbps.

7.3.5 DC Breakdown Voltage

The DC breakdown voltage of each I/O pin is a minimum of ±5.5 V. This ensures that sensitive equipment is protected from surges above the reverse standoff voltage of ±3.6 V.

7.3.6 Ultra Low Leakage Current

The I/O pins feature an ultra-low leakage current of 10 nA (max) with a bias of ±2.5 V

7.3.7 Low ESD Clamping Voltage

The I/O pins feature an ESD clamp that is capable of clamping the voltage to 8.8 V (IPP = 5 A).

7.3.8 Supports High Speed Interfaces

This device is capable of supporting high speed interfaces up to 10 Gbps, because of the extremely low IO capacitance.

7.3.9 Industrial Temperature Range

This device features an industrial operating range of –40°C to 125°C.

7.3.10 Easy Flow-Through Routing Package

The layout of this device makes it simple and easy to add protection to an existing layout. The packages offers flow-through routing, requiring minimal modification to an existing layout.

7.4 Device Functional Modes

The TPD4E02B04 is a passive integrated circuit that triggers when voltages are above VBRF or below VBRR. During ESD events, voltages as high as ±15 kV (air) can be directed to ground via the internal diode network. When the voltages on the protected line fall below the trigger levels of TPD4E02B04 (usually within 10s of nano-seconds) the device reverts to passive.
