Notes:
2. In automotive and 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 het same
supply voltage source as the device or control line under protection, a current limiti ng resistor should be connected in series between the external supply and the SP721 supply pins to
limit reverse battery current to within the rated maximum limits. Bypass capacitors of typically 0.01μF or larger romf the V+ and V- Pins to ground are recommended.
3. Refer to the Figure 3 graph for definitions of equivalent “SCR ON Threshold” and “SCR ON Resistance”. These characteristics are given here for thumb-rule nformation to determine peak
current and dissipation under EOS conditions.
