Overview

TVS Diode Arrays Electronic Protection Array for ESD and Overvoltage Protection SP721 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 device 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 ...
