15. ESD 8KV Contact Test for ultra low capacitance Comparisons Remark1: Low Ir (leakage current) measured at DC 6V. Remark2: All the protection device expect SFI are polymer devices. These polymer device contain physically elastic material, their performance degrades based on the number of ESD pulses they received. These polymer devices lifetimes vary 20 ESD pulses to 500 pulses. Remark3: SFI ESD protection devices are manufactured by ceramic. SFI protect devices withstand more then 2000 ESD pulses. Actually, the life time SFI device are unlimited. - - - 0.18~ 2.05 119~265 2000 25~30 0 0.20~ 0.26 751~948 - - 0.20~ 2.13 117~262 1000 0.20~ 0.50 75~97 0.20~0.26 602~846 20~26 0 0.19~ 0.75 125~405 500 0.19~ 0.30 75~142 0.19~0.27 498~799 0.19~ 0.28 79~113 0.21~ 1.07 143~237 250 0.19~ 0.27 91~332 0.19~0.26 167~511 0.19~ 0.27 117~345 0.21~ 0.27 159~267 0 Ir (μA) Breakdown voltage (V) Ir (μA) Breakdown voltage (V) Ir (μA) Breakdown voltage (V) Ir (μA) Breakdown voltage (V) T Product C Product I Product SFI ESD 8Kv contact strikes
