For applications of 18V DC or less. Higher voltages available, contact your Littelfuse Sales Representative. 2. Tested with IEC-61000-4-2 Human Body Model (HBM) discharge test circuit. 3. Direct discharge to device terminals (IEC preferred test method). 4. Corona discharge through air (represents actual ESD event). 5. Capacitance may be customized, contact your Littelfuse Sales Representative. 6. Leakage current ratings are at 18 V DC and 25 A maximum. 7. The typical capacitance rating is the discrete component test result. 8. Items are lead free, and available as "R" packing option only. 25 0 1 CURRENT (A) NOMINAL VOLTAGE AT 1mADC 10 100 1000 10000 5 10 15 20 30 1.2 0.0 0.0001 25 0.001 0.01 0.1 1 CURRENT (mA) NORMALIZED VARISTOR VOLTAGE (V) 1.0 0.8 0.6 0.4 0.2 85 125 O 100 80 60 40 20 0 -55 50 60 70 80 90 100 110 120 130 140 150 PERCENT OF RATED VALUE AMBIENT TEMPERATURE ( o C) Figure 1 Figure 2 Figure 3 Figure 4
