The TPD2EUSB30A offers low 4.5-V DC breakdown voltage. The low capacitance, low break-down
voltage, and low dynamic resistance make the
TPD2EUSB30A a superior protection device for highspeed differential IOs.
The TPD2EUSB30 and TPD2EUSB30A are offered
in space saving DRT (1 mm × 1 mm) package. The
TPD4EUSB30 is offered in space saving DQA (2.5

7 Detailed Description
7.1 Overview
The TPD2EUSB30, TPD2EUSB30A, and TPD4EUSB30 are 2 and 4 channel Transient Voltage Suppressor
(TVS) based Electrostatic Discharge (ESD) protection diode arrays. The TPDxEUSB30/A devices are rated
to dissipate ESD strikes at the maximum contact level specified in the IEC 61000-4-2 international standard
(Contact). These devices also offer 5 A (8/20 μs) peak pulse current ratings per IEC 61000-4-5 (surge)
specification.

7.3 Feature Description
TPDxEUSB30/A is a family of uni-directional Electrostatic Discharge (ESD) protection devices with low
capacitance. Each IO line is rated to dissipate ESD strikes at or above the maximum level specified in the
IEC 61000-4-2 (Level 4 Contact) international standard. The TPDxEUSB30/A's low loading capacitance makes it
ideal for protection super speed high-speed signals.
7.4 Device Functional Modes
The TPDxEUSB30/A family of devices are passive integrated circuits that activate whenever voltages above
VBR or below the lower diodes Vforward (–0.6V) are present upon the circuit being protected. During ESD events,
voltages as high as ±8 kV (contact) can be directed to ground via the internal diode network. Once the voltages
on the protected lines fall below the trigger voltage of the device (usually within 10's of nano-seconds) the device
reverts to passive.

8 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
8.1 Application Information
The TPDxEUSB30/A family is a family of diode array type transient voltage suppressors (TVS) which are
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.
8.2 Typical Application
This application describes a TPDxEUSB30/A eye pattern test. Figure 10-2 shows the lab board that was
designed to demonstrate the degradation of the eye pattern quality with and without the TPD2EUSB30/A in the
USB 3.0 signal path. The measurements show that there is only ~2 ps jitter penalty to the differential signal
when the TPD2EUSB30/A device is added in the signal path. A similar setup was employed to measure the eye
diagram for the TPD4EUSB30.

For this design example, a single TPD2EUSB30/A is used to protect a differential data pair lines, similar to a
USB 3.0 application. Given the USB application, the following parameters are known.

8.2.2 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
8.2.2.1 Signal Range on D+, D- Pins
The TPD2EUSB30 has 2 pins which support 0 to 5.5 V and the TPD2EUSB30A has 2 pins which support 0 to
3.6 V.
8.2.2.2 Operating Frequency
The 0.7 pF (TPD2EUSB30/A typ) line capacitance supports data rates in excess of 5 Gbps.

9 Power Supply Recommendations
This family of devices are passive ESD protection devices and there is no need to power them. Care should be
taken to not violate the maximum voltage specification to ensure that the device functions properly. The D+ and
D– lines share a TVS diode which can tolerate up to 6 V.
10 Layout
10.1 Layout Guidelines
•
•
•
The optimum placement is as close to the connector as possible.
– EMI during an ESD event can couple from the trace being struck to other nearby unprotected traces,
resulting in early system failures.
– The PCB designer needs to minimize the possibility of EMI coupling by keeping any unprotected traces
away from the protected traces which are between the TVS and the connector.
Route the protected traces as straight as possible.
Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded
corners with the largest radii possible.
– Electric fields tend to build up on corners, increasing EMI coupling.
Refer to Figure 10-1, the TPD2EUSB30/A are offered in space saving DRT package. The DRT is a 1-mm ×
1-mm package with flow-through pin-mapping for the high-speed differential lines. The TPD4EUSB30 is offered
in space saving DQA package. The DQA is a 1-mm × 2.5-mm package with flow-through pin-mapping for the
high-speed differential lines. It is recommended to place the package right next to the USB 3.0 connector.
The GND pin should connected to GND plane of the board through a large VIA. If a dedicated GND plane is
not present right underneath, it is recommended to route to the GND plane through a wide trace. The current
associated with IEC ESD stress can be in the range of 30Amps or higher momentarily. A good, low impedance
GND path ensures the system robustness against IEC ESD stress.
The TPDxEUSB30/A can provide system level ESD protection to the high-speed differential ports (> 5 Gbps data
rate). The flow-through package offers flexibility for board routing with traces up to 15 mills wide. It allows the
differential signal pairs couple together right after they touch the ESD ports of the TPDxEUSB30/A.

11.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
