Electronic Protection Array For ESD And Overvoltage Protection

The SP723 is an array of SCR Diode bipolar structures for ESD and over-voltage protection of sensitive input circuits. The SP723 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 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. Refer to Fig 1 and Table 1 for further details. Refer to Application Note AN9304 and AN9612 for further detail. By littelfuse
