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 IP4085CX4 IP4385CX4 IP4386CX4 IP4387CX4 Integrated high-performance ESD protection diodes Rev. 2 14 December 2012 Product data sheet 1. Product profile 1.1 General description Integrated high-performance protection diodes protecting appliances against ElectroStatic Discharge (ESD) of 30 kV, far exceeding IEC 61000-4-2 level 4 standard, overvoltage and wrong polarity. Each device includes one high-level ESD protection diode in a 4-channel 0.4 mm (IP438xCX4) or 0.5 mm (IP4085CX4) pitch Wafer Level Chip-Size Package (WLCSP). The anode and the cathode of ESD protection diode are each connected to two solder balls. 1.2 Features and benefits Single integrated high-performance ESD protection diode Surge immunity according to IEC 61000-4-5 (8/20 s) up to 60 A (IP4085CX4) ESD protection of >30 kV contact discharge, far exceeding IEC 61000-4-2, level 4 Small 2 2 solder ball WLCSP package with 0.4 mm or 0.5 mm pitch 1.3 Applications General-purpose ESD protection such as for charger interfaces in: Mobile handsets Portable devices Wireless data systems
