The Littelfuse SC1333-01ETG back-to-back diodes are fabricated in a proprietary silicon avalanche technology. These diodes provide a high ESD (electrostatic discharge) protection level for electronic equipment. The SC1333-01ETG TVS can safely absorb repetitive ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation. The back-to-back configuration provides symmetrical ESD protection for data lines. Additionally, the SC1333-01ETG offers up to 5A 8/20μs surge rating with low clamping voltages.ESD, IEC 61000-4-2, ±30kV contact, ±30kV air EFT, IEC 61000-4-4, 40A (5/50ns) Lightning, IEC 61000-4- 5, 2nd Edition, 5A (8/20μs) Low capacitance of 8pF (TYP @ VR=0V) Low leakage current of 1nA (TYP) at 3.3VSpace Efficient 0402 Halogen free, Lead free and RoHS compliant Moisture Sensitivity Level (MSL -1)
