JA is measured with the component mounted on an evaluation PC board in free air. 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 0.01F 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. +V CC INPUT DRIVERS SP721 INPUT PROTECTION CIRCUIT (1 OF 6 SHOWN) OR SIGNAL SOURCES IN 5 - 7 IN 1 - 3 SP721 V- TO +V CC LINEAR OR DIGITAL IC INTERFACE V+ +V CC (Application as an Input Clamp for Over-voltage, Greater than 1V BE Above V+ or less than -1V BE below V-) Typical Application of the SP721
