The ESD protection provided by the component enables the data port to withstand ±8 KV Contact / ±15 KV Air Discharge when tested according to the method specified in IEC 61000-4-2. The component incorporates 7 identical channels and is supplied in a 20 pin CSP package which is intended to be mounted directly onto an FR4 printed circuit board. This package will meet typical thermal cycle and bend test specifications without the use of an underfill material.

The IEC 61000-4-2 test method will be adapted for component level testing. The device will provide the specified ESD protection performance on the “IN 1-7” pins only. 2. “Let Through” is a measure of the component of an incident ESD transient that the protection device allows through to the down stream circuitry. *RoHS Directive 2002/95/EC Jan 27 2003 including Annex Specifications are subject to change without notice.

Solder bumps, formed on the Silicon die, provide the interconnect medium from die to PCB. The bumps are arranged on the die in a regular grid formation. The grid pitch is 0.5mm. The dimensions for the CSP packaged device are shown in Fig. 2 below. 248.5 ± 45 (9.78 ± 1.78) 858 ± 40 (33.78 ± 1.57) BUMP A1/PIN 1 INDICATOR A1 BOURNS LOGO B1 A2 B2 C1 D1 C2 D2 300 DIA.

A 25-Pin Daisy Chain component is available from Bourns for this purpose (part number 2TAD-C25R). This is a 5 x 5 array featuring 0.5mm pitch solder bumps. The Distance to Neutral Point (DNP) on that component is larger than that of the 2FAH-C20R and is thus deemed a worse case for Thermal Cycle testing. “Silicon level” reliability performance will be assured by similarity to other Integrated Passive and Active Devices using CSP product from Bourns. Individual Channel Schematic This section contains the schematic (See Fig. 3 below) for the single channel in the integrated passive device. Note that the electrical parameters of primary interest are (a) DC Resistance and (b) ESD performance. In terms of DC parameters it should be noted that all resistor values have a tolerance of ±10 %. This schematic consists of a series 100ohm resistance and Back to Back Zener 6.5 Volt diodes for ESD protection.
