1.1 General description
The IP4302CX2/A is a bidirectional diode which is designed to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as 15 kV contact discharge according to the IEC 61000-4-2 model, far exceeding standard level 4. The device is fabricated using monolithic silicon technology and integrates one pair of back-to-back diodes in a 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP). These features make the IP4302CX2/A ideal for use in applications requiring the utmost in miniaturization such as mobile phone handsets, cordless telephones and other portable electronic devices.

Product data sheet Rev. 1 — 28 November 2011 4 of 10 NXP Semiconductors IP4302CX2/A Low profile bidirectional ESD protection diode 6. Application information The IP4302CX2/A is designed for the protection of one bidirectional data or signal line from the damage caused by ESD. The device may be used on lines where the signal polarities are both, positive and negative with respect to ground.
6.1 Printed-Circuit Board (PCB) layout and prot ection device placement
PCB layout is critical for the suppression of ESD and Electric Fast Transient (EFT). The following guidelines are recommended: 1. Place the device as close as possible to the input terminal or connector 2. The path length between the device an d the protected line should be minimized 3. Keep parallel signal paths to a minimum 4. Avoid running protected conductors in parallel with unprotected conductors 5. Minimize all PCB conductive loops including power and ground loops 6. Minimize the length of the transient return path to ground 7. Avoid using shared transient return paths to a common ground point Fig 1.
