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.
