SP720 Series 3pF 4kV Diode Array
■ 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 +V BE diode threshold above V+ (Pin 16) or a -V BE 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 V BE above V+. A similar clamp to V-is activated if a negative pulse, one V BE less than V-, is applied to an IN input. Standard ESD Human Body Model (HBM) Capability is:
