2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 02/23/17 TVS Diode Arrays (SPA Diodes) General Purpose ESD Protection - SP724 Series Absolute Maximum Ratings Parameter Rating Units Continuous Supply Voltage, (V+) - (V-) +20 V Forward Peak Current, I IN to V CC , GND (Refer to Figure 5) 2.2, 100s A Electrical Characteristics T A = -40 o C to 105 o C, V IN = 0.5V CC , Unless Otherwise Specified Thermal Information Parameter Rating Units Thermal Resistance (Typical, Note 3) JA o C/W SOT Package 220 o C/W Maximum Storage Temperature Range -65 to 150 o C Maximum Junction Temperature 150 o C Maximum Lead Temperature (Soldering 20-40s) (SOT - Lead Tips Only) 260 o C CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Note: 3. JA is measured with the component mounted on an evaluation PC board in free air.

In automotive and other battery charging systems, the SP724 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, a current limiting resistor should be connected in series between the external supply and the SP724 supply pins to limit reverse battery current to within the rated maximum limits. 5. Bypass capacitors of typically 0.01F or larger should be connected closely between the V+ and V- Pins for all applications. 6. Refer to the Figure 3 graph for definitions of equivalent "SCR ON Threshold" and "SCR ON Resistance". These characteristics are given here for information to determine peak current and dissipation under EOS conditions.
