IP4234CZ6

Single USB 2.0 ESD protection to IEC 61000-4-2 level 4

Rev. 3.0 — 31 January 2018

Product data sheet

1 Product profile

1.1 General description

The IP4234CZ6 is designed to protect Input/Output (I/O) USB 2.0 ports, that are sensitive

to capacitive loads, from being damaged by ElectroStatic Discharge (ESD). The π-

filter structure is implemented with a small series resistor to provide the necessary

protection to signal and supply components from ESD voltages greater than ±8 kV

contact discharge according IEC 61000-4-2, level 4.

The ESD protection is independent of the supply voltage due to the rail-to-rail diode

architecture being connected to a Zener diode.

The IP4234CZ6 is fabricated using monolithic silicon technology and integrates two ultra-

low capacitance π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead

SOT457 package.

1.2 Features

• Pb-free and RoHS compliant

• Simple, direct signal routing provides for high speed signal integrity

• ESD protection compliant to IEC 61000-4-2 level 4, ±8 kV contact discharge

• Four low input capacitance (3.1 pF typical) rail-to-rail ESD protection diodest

• Low voltage clamping due to an integrated Zener diode

• Small 6-lead SO6 (SOT457) package

• IEC 61000-4-5 15 A Lightning (8/20 μs) compliant

1.3 Applications

• General-purpose downstream ESD protection high frequency analog signals and high-

speed serial data transmission for ports inside:

– Cellular and PCS mobile handsets

– PC/Notebook USB2.0/IEEE1394 ports

– DVI interfaces

– HDMI interfaces

– Cordless telephones

– Wireless data (WAN/LAN) systems

– PDAs

9 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”.

9.1 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.

9.2 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

9.3 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

9.4 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

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.
