IP4233CZ6 Ultra low capacitance ESD protection for Ethernet ports Rev. 3 — 17 June 2010 Product data sheet 1. Product profile 1.1 General description The IP4233CZ6 is designed to protect Input/Output (I/O) ports that are sensitive to capacitive loads, such as Ethernet, from destruction by ElectroStatic Discharge (ESD). The IP4233CZ6 incorporates two pairs of ultra low capacitance back-to-back diodes which protect components from ESD voltages as high as ±8 kV contact discharge according to IEC 61000-4-2, level 4. The back-to-back diodes prevent negative clipping of AC signals and voltages below zero. The IP4233CZ6 is fabricated using monolithic silicon technology integrating two ultra low capacitance back-to-back ESD protection diodes in a very small 6-lead SOT363 package. 1.2 Features and benefits Pb-free and Restriction of Hazardous Substances (RoHS) compliant ESD protection compliant to IEC 61000-4-2 level 4, ±8 kV contact discharge Two low input capacitance (0.9 pF typical) back-to-back ESD protection diodes Very small 6-lead SOT363 package 1.3 Applications ESD protection high-frequency AC-coupled Ethernet ports 1.4 Quick reference data Table 1.

Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 8.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 8.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • • • • • • Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 8.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities IP4233CZ6 Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 5 of 11 IP4233CZ6 NXP Semiconductors Ultra low capacitance ESD protection for Ethernet ports 8.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 3) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 6 and 7 Table 6. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (°C) Volume (mm3) < 350 ≥ 350 < 2.5 235 220 ≥ 2.5 220 220 Table 7. Lead-free process (from J-STD-020C) Package thickness (mm) Package reflow temperature (°C) Volume (mm3) < 350 350 to 2000 > 2000 < 1.6 260 260 260 1.6 to 2.5 260 250 245 > 2.5 250 245 245 Moisture sensitivity precautions, as indicated on the packing, must be respected at all times. Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 3.
