Each channel consists of a pair of diodes that steer ESD current pulses to VCC or GND. The TPD4E001 protects against ESD pulses up to ±15-kV Human-Body Model (HBM), ±8-kV Contact Discharge, and ±15-kV Air-Gap Discharge, as specified in IEC 61000-4-2. This device has a 1.5-pF capacitance per channel, making it ideal for use in high-speed data IO interfaces. The TPD4E001 is a quad-ESD structure designed for Ethernet and FireWire™ applications. The TPD4E001 is available in DRL and thin QFN packages and is specified for –40°C to 85°C operation.

The TPD4E001 ensures that the core circuitry is protected and the system is functioning properly in the event of an ESD strike. For proper operation, the following layout/ design guidelines should be followed: 1. Place the TPD4E001 solution close to the connector. This allows the TPD4E001 to take away the energy associated with ESD strike before it reaches the internal circuitry of the system board. 2. Place a 0.1-µF capacitor very close to the VCC pin. This limits any momentary voltage surge at the IO pin during the ESD strike event. 3. Ensure that there is enough metallization for the VCC and GND loop. During normal operation, the TPD4E001 consumes nA leakage current. But during the ESD event, VCC and GND may see 15 A to 30 A of current, depending on the ESD level. Sufficient current path enables safe discharge of all the energy associated with the ESD strike. 4. Leave the unused IO pins floating . 5. The VCC pin can be connected in two different ways: a. If the VCC pin is connected to the system power supply, the TPD4E001 works as a transient suppressor for any signal swing above VCC + VF. A 0.1-µF capacitor on the device VCC pin is recommended for ESD bypass. b. If the VCC pin is not connected to the system power supply, the TPD4E001 can tolerate higher signal swing in the range up to 10V. Please note that a 0.1µF capacitor is still recommended at the VCC pin for ESD bypass.
