The SP720 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP720 has 2 protection SCR/Diode device structures per input. A total of 14 available inputs can be used to protect up to 14 external signal or bus lines. Over-voltage protection is from the IN (pins 1-7 and 9-15) to V+ or V-.

The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 16) or a -VBE diode threshold below V- (Pin 8). From an IN input, a clamp to V+ is activated if a transient pulse causes the input to be increased to a voltage level greater than one VBE above V+. A similar clamp to V- is activated if a negative pulse, one VBE less than V-, is applied to an IN input.

pdficon IEC 61000 4 2 ESD Immunity and Transient Current Capability for the SP72X Series Protection Arrays Application Note

This application note covers IEC 61000-4-2 ESD immunity and transient current capability for the SP72X Series protection arrays. The SP720 SP721 SP723 and SP724 are protection ICs with an array of SCR/Diode bipolar structures for ESD and over-voltage protection of sensitive input circuits. They have 2 protection SCR/Diode device structures per input.

pdficon ESD and Transient Protection Using the SP720 Application Note

This application note discusses ESD and transient protection using the SP720. For a given level of voltage or power there is a defined degree of protection compatible to that need. For the SP720 the protection circuits are designed to clamp over-voltage within a range of peak current that will substantially improve the survival input expectancy of average monolithic silicon circuits used for small signal and digital processing applications.

pdficon SP720 SP721 and SP723 Turn-On and Turn-Off Characteristics Application Note

The purpose of this application note is to focus on customer concerns related to the fast switching characteristics of the SP720 SP721 and SP723 family of protection ICs during an ESD discharge. The SCR cell structures of this family were first introduced for ESD protection of sensitive ICs that were subject to substantially more severe conditions than normal Human Body Model stress.
