TVS Diode Arrays (SPA Diodes) General Purpose ESD Protection - SP723 Series RoHS Pb GREEN SP723 Series 5pF 8kV Diode Array Description 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 +V diode threshold above V+ (Pin 8) or BE a -V diode threshold below V- (Pin 4). From an IN input, BE a clamp to V+ is activated if a transient pulse causes the input to be increased to a voltage level greater than one V above V+. A similar clamp to V- is activated if a negative BE Pinout pulse, one V less than V-, is applied to an IN input. BE Refer to Fig 1 and Table 1 for further details. Refer to IN 1 8 V+ Application Note AN9304 and AN9612 for further detail.

In automotive ans battery operated systems, the power supply lines should be externally protected for load dump and reverse battery. When the V+ and V- Pins are connected to the same supply voltage source as the device or control line under protection, acurrent limiting resistor should be connectied in series between the external supply and the SP723 supply pins to limit reverse battery current to within the rated maximum limits. Bypass capacitors of typically 0.01F or larger from the V+ and V- Pins to ground are recommended. 3. Refer to the Figure 3 graph for determine peak current and dessipation under EOS conditions.
