IP4059CX5

The Nexperia IP4059CX5 is a monolithic silicon ESD protection diode designed to safeguard I/O pins on computer interfaces like USB 2.0, USB On-The-Go (OTG), and Ethernet. It provides protection against electrostatic discharge voltages up to ±8 kV contact discharge according to IEC 61000-4-2.

This device integrates four ultra-low capacity ESD protection diodes with a typical capacitance of 3.0 pF. It features a typical reverse standoff voltage of 5.5V and a minimum breakdown voltage of 6V. The IP4059CX5 is fabricated using monolithic silicon technology and comes in a compact 0.5 mm pitch Wafer-Level Chip-Scale Package (WLCSP).

The IP4059CX5 is suitable for applications requiring general-purpose ElectroMagnetic Interference (EMI) and Radio Frequency Interference (RFI) filtering, along with downstream ESD protection for USB ports. Its small form factor and robust protection capabilities make it ideal for use in cellular handsets, PC peripherals, cordless telephones, wireless data systems, and digital cameras. The device operates within a temperature range of -40°C to 85°C and is mounted using a surface mount technique. It is Pb-free, RoHS compliant, and free of halogen and antimony.

Key specifications include ±8 kV contact discharge and ±15 kV air discharge ESD protection, 3.0 pF capacitance, 5.5V reverse standoff voltage, and 6V minimum breakdown voltage. The WLCSP package measures 0.96 mm by 1.34 mm.
