SP721ABG - SP721 Lead-Free/Green Series

SP721_SP723
The SP721 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP721 has 2 protection SCR/Diode structures per input. There are a total of 6 available inputs that can be used to protect up to 6 external signal or bus lines. Over voltage protection is from the IN (Pins 1-3 and Pins 5-7) to V+ or V-. The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 8) or a –VBE diode threshold below V- (Pin 4). 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.

pdf icon 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.

pdf icon 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.
