Product profile 1.1 General description The device is designed to protect high-speed interfaces such as High-Definition Multimedia Interface (HDMI), DisplayPort, USB, external Serial Advanced Technology Attachment (eSATA) and Low Voltage Differential Signaling (LVDS) interfaces against ElectroStatic Discharge (ESD). The device includes high-level ESD protection diodes structure for high-speed signal lines in a 4-channel 0.4 mm pitch single Wafer-Level Chip-Scale Package (WLCSP). These features make the device ideal for use in applications requiring component miniaturization such as mobile phone handsets and other portable electronic devices. All signal lines are protected by a special diode configuration offering ultra low line capacitance of 0.8 pF (typical). These diodes provide protection to downstream components from ESD voltages up to 8 kV contact according to IEC 61000-4-2, level 4. 1.2 Features and benefits  Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant)  System ESD protection for USB 2.0, USB On-The-Go (USB OTG), Ethernet and Digital Visual Interface (DVI)  All signal lines with integrated rail-to-rail clamping diodes structure for downstream ESD protection of 8 kV according to IEC 61000-4-2, level 4  2  2 solder ball WLCSP with 0.4 mm pitch and height < 500 m  Signal lines with  0.05 pF matching capacitance between signal pairs  Line capacitance of only 0.8 pF for each channel 1.3 Applications The device is designed for high-speed receiver and transmitter port protection:  Portable devices  Mobile handsets  Wireless data systems  Digital cameras IP4369CX4 Nexperia ESD protection for high-speed interfaces 2.

Dynamic resistance with negative clamping The device uses an advanced clamping structure showing a negative dynamic resistance. This snap-back behavior strongly reduces the clamping voltage to the system behind the ESD protection during an ESD event. Do not connect unlimited DC current sources to the data lines to avoid keeping the ESD protection device in snap-back state after exceeding breakdown voltage (due to an ESD pulse for instance). 018aaa235 4 VCL (V) (1) 018aaa236 3 VCL (V) 3 (2) 2 (3) (1) 2 (2) (3) 1 1 0 0.0 0 1.5 3.0 4.5 0 2 4 6 ICL (A) ICL (A) IEC 61000-4-5 IEC 61000-4-5 (1) Tamb = 25 C; y = 0.21x + 2.86 (1) Tamb = 25 C; y = 0.16x + 1.52 (2) Tamb = 75 C (2) Tamb = 75 C (3) Tamb = 125 C (3) Tamb = 125 C Fig 11.

Design and assembly recommendations 7.1 PCB design guidelines For optimum performance, use a Non-Solder Mask Defined (NSMD), also known as a copper-defined design, incorporating laser-drilled micro-vias connecting the ground pads to a buried ground-plane layer. This results in the lowest possible ground inductance and provides the best high frequency and ESD performance. Refer to Table 6 for the recommended Printed-Circuit Board (PCB) design parameters.
