9 Applications and Implementation

9.1 Application Information

TPD4E110 is a diode array type Transient Voltage Suppressor (TVS) which is typically used to provide a path to ground for dissipating ESD events on hi-speed signal lines between a human interface connector and a system. As the current from ESD passes through the TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC. The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a tolerable level to the protected IC.

9.2 Typical Application

9.2.1 Design Requirements

For this design example, use the following as the input parameters.

Table 1. Design Parameters

DESIGN PARAMETER EXAMPLE VALUE
Signal range on Pin 1, 2, 3, or 4 0V to 5.5V
Operating Frequency 3.0 GHz

9.2.2 Detailed Design Procedure

To begin the design process some parameters must be decided upon. The designer needs to know the following:

  • Signal range on all the protected lines
  • Operating frequency

9.2.2.1 Signal range on Terminal 1, 2, 3, or 4

TPD4E110 has 4 identical protection channels for signal lines. The symmetry of TPD4E110 provides flexibility when selecting which of the 4 IO channels will protect which signal lines. Any IO will support a signal range of 0V to 5.5V.

9.2.2.2 Operating Frequency

The 0.45pF capacitance of each IO channel supports data rates up to 6Gbps.
