Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of IP4340CX15 6-channel filter for ESD protection of microSD memory card interfaces Rev. 2 13 August 2012 Product data sheet 1. Product profile 1.1 General description Array of 13 diodes and 11 resistors designed to protect downstream components against ElectroStatic Discharge (ESD) voltages as high as 15 kV. The device is encapsulated in a 1.56 mm 1.56 mm Wafer-Level Chip-Scale Package (WLCSP) fabricated using monolithic silicon semiconductor technology. These features make the device ideal for use in applications requiring a high degree of miniaturization, such as mobile phone handsets, cordless telephones and personal digital devices. 1.2 Features and benefits Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant) Integrated ESD protection, ElectroMagnetic Interference (EMI) and RF filtering for microSD memory card channels ESD protection up to 15 kV on 6 channels at output terminals Integrated EMI and RF filters with pull-up resistors (on 5 channels) Additional power supply protection WLCSP with 0.4 mm pitch 1.3 Applications MicroSD memory card interfaces in cellular phone and Personal Communication System (PCS) mobile handsets Cordless telephones Digital still and video cameras Media players Card readers
