The SP725 is an array of SCR/Diode bipolar structures for ESD and overvoltage protection of sensitive input circuits. The SP725 has 2 protection SCR/Diode device structures per input. There are a total of 4 available inputs that can be used to protect up to 4 external signal or bus lines. Over-voltage protection is from the IN (Pins 1 - 4) to V+ or V-.

The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 5,6) or one –VBE diode threshold below V- (Pin 7,8). 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 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 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.
