TPD4E02B04DQAR Description

The TVS ESD safety diode array TPD4E02B04 protects USB Type-C and HDMI 2.0 circuits in both directions. The worldwide standard IEC 61000-4-2 says that the TPD4E02B04 can handle electrostatic discharges (ESDs) at the highest level, which is Level 4. This device’s 0.25-pF IO capacitance per channel makes it easy to protect high-speed connections up to 10 Gbps, like USB 3.1 Gen2.

The TPD4E02B04 can be bought in this format, which is standardized on the USON-10 (DQA) format. The 0.5 mm pin spacing and flow-through wiring of the package make it easy to use and speed up the design process.

TPD4E02B04DQAR Detailed Description

The TPD4E02B04 is an ESD protection diode that works in both directions and has very low capacitance. This gadget can stop ESD strikes that are stronger than what the IEC 61000-4-2 International Standard says is safe. This device is great for protecting any super-high-speed data pins because it has a very low capacitance.

Features

• DC Breakdown Voltage: 5.5 V (Minimum).
• The maximum leakage current is 10 nA.
• 8 V at 5 A TLP is a low ESD clamping voltage.
• Up to 10 Gbps high-speed interfaces are supported.
• The range of temperatures in industry is from -40 °C to +125°C.
• The flow-through routing package is easy to use.

Feature Description

● IEC 61000-4-2 ESD

The TPD4E02B04DQAR device offers strong ESD protection, capable of withstanding ESD events up to 12 kV contact and 15 kV air gap. It incorporates an integrated ESD surge clamp that efficiently diverts current to ground, safeguarding the device and ensuring its reliable operation during ESD events.

● IEC 61000-4-5 Surge Protection

The I/O pins of the TPD4E02B04DQAR can handle surges of up to 2 A and 17 W with an 8/20 s pattern. This means that the tool can’t be broken by too much power or a sudden surge of electricity. The TPD4E02B04DQAR is built with an ESD-surge clamp to protect the circuits inside from damage.

This clamp successfully sends the current to ground so that surges don’t damage the device. The ESD-surge clamp and the TPD4E02B04DQAR’s strong surge protection features make it a great choice for cases where you need to protect against high currents and power surges.

● IO Capacitance

The amount of space between each I/O pin and ground is usually 0.25 pF and at most 0.33 pF. This gadget can handle up to 10 Gbps of data.

● DC breakdown voltage

Each I/O pin on the TPD4E02B04DQAR has a DC breakdown value of at least 5.5 V. This feature makes sure that sensitive equipment is safe from spikes that are higher than the reverse standoff voltage of 3.6 V. This protects against high-voltage events that could cause damage.

● Ultra-low leakage current

The I/O pins have a bias of 2.5 V and a leaking current of no more than 10 nA.

● Supports high-speed interfaces

Because the IO capacitance is so low, this device can handle high-speed interfaces of up to 10 Gbps.

● Easy Flow-Through Routing Package

The way this device is set up makes it simple and easy to add safety to a layout that is already in place. The packages offer flow-through routing, which means that a current layout needs only minor changes.

Device Functional Modes

The TPD4E02B04 is an inactive integrated circuit that turns on when the voltage is higher than VBRF or lower than VBRR. The combined diode network can safely send ESD events with voltages up to 15 kV (air) to ground. When the voltage on the shielded line drops below the trigger levels, which usually happens in less than 10 ns, TPD4E02B04 goes back to passive mode.

TPD4E02B04DQAR Application Information

The TPD4E02B04 is a TVS diode that is used to send ESD events on high-speed data lines between a human interface connector and a system to ground. As the ESD current flows through the TVS, there is only a small drop in voltage across the diode. This is the power that goes to the IC that is being protected. This voltage, VCLAMP, stays at a safe level for the protected IC because the activated TVS has a low RDYN.

Power Supply Recommendations

The TPD4E02B04DQAR is a passive electrostatic discharge (ESD) device that does not need a power source to work. It works by protecting against voltage spikes and fluctuations between -3.6 V and 3.6 V.

To make sure the TPD4E02B04DQAR works right, you must stick to the suggested input/output (I/O) range of -3.6 V to 3.6 V. This means that the energy that goes into the device shouldn’t go below -3.6 V or above 3.6 V.

By following these rules and keeping within the specified voltage range, you can use the TPD4E02B04DQAR TVS diode for its intended purpose, which is to protect against electrostatic discharge and voltage transients.

Layout Guidelines

The optimum placement is as close to the connector as possible.

• EMI can spread from the trace that was hit by an ESD to other close, unprotected traces, causing the system to fail early.
• The PCB designer must keep any exposed traces away from the protected traces that are between the TVS and the connector to reduce the chance of EMI coupling.

Route the shielded wires as straight as possible.

Remove any sharp corners from the protected traces between the TVS and the socket by using rounded corners with the largest radii possible.

• Corners are places where electric fields tend to build up, which makes EMI coupling worse.

Conclusion

In conclusion, the TVS ESD safety diode array TPD4E02B04 is a very reliable and effective way to protect USB Type-C and HDMI 2.0 circuits from electrostatic discharges (ESDs) and voltage transients. It meets the IEC 61000-4-2 Level 4 standard, so it has strong ESD safety and can handle up to 12-kV contact and 15-kV air gap events. With a low capacitance of 0.25 pF IO per channel, it can protect high-speed links of up to 10 Gbps. This makes it perfect for USB 3.1 Gen2 interfaces.

Also, the TPD4E02B04DQAR has some amazing features, such as a DC breakdown voltage of 5.5 V, an ultra-low leakage current of 10 nA, and a low ESD clamping voltage of 8.8 V at 5 A TLP. It guards against surges of up to 2 A and 17 W, ensuring that excessive power or sudden electrical surges won’t harm the device. It can work in a wide range of temperatures, from -40°C to +125°C, and is reliable in many workplace settings.
