EClamp8052P is an easily implemented solution for replacing discrete common mode chokes and ESD protection devices in a single package. These devices utilize silicon avalanche technology for superior ESD and TLP clamping performance. They feature high maximum ESD withstand voltage of +/- 25kV contact, +/-30kV air discharge per IEC 61000-4-2. The integrated common-mode choke has a typical differential mode cutoff frequency >3GHZ and typical common mode suppression of 10dB at 500MHz and 15dB from 1GHz to 2.8GHz. Each channel series resistance is 1.8 Ohms maximum.

Application Information USB Interface Protection EClamp8052P may be used to protect D+ and D- lines against ESD and EMI in USB 2.0, USB 3.0, and USB 3.1 applications. USB D+ and D- lines enter at pins 1 and 2 (connector side) and exit at pins 4 and 5. The TVS diodes are internally connected at pins 1 and 2 and therfore must be located towards the connector on the PCB. Pin 3 is connected to the ground plane. Figures 1 is an example of protecting a USB 3.0 Type-A interface (host side shown). For USB 3.0 applications, RClamp3324T is recommended for protecting the 5Gb/s SuperSpeed line pairs. Lines are routed through the device at pins 1-4. Traces should be kept the same length to avoid impedance mismatch. Ground is connected at pins 5 and 6. The differential impedance of each pair can be controlled for USB 3.0 (85 Ohms +/-15%) while maintaining a minimum trace-totrace and trace-to-pad spacing. Individual PCB design constraints may necessitate different spacing or trace
width. Both ground pads should be connected for optimal performance. Ground connection is made using filled via-in-pad. Additional information may be found on the device data sheet. Single line devices such as uClamp0571P are recommended for surge and ESD protection of the VBus line. This device features high surge and ESD capability and may be used on 5V power rails. Device Placement Placement of the protection component is a critical element for effective ESD suppression. TVS diodes should be placed as close to the connector as possible. This helps reduce transient coupling to nearby traces. Ground connections should be made directly to the ground plane using micro-vias. This reduces parasitic inductance in the ground path and minimizes the clamping voltage seen by the protected device.
