TVS DIODE ARRAYS TVS Diode Arrays Electronic Protection Array for ESD and Overvoltage Protection SP720 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 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+.
