The SP1103C includes TVS diodes fabricated in a proprietary silicon avalanche technology protect each I/O pin to provide a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). 这种二极管功能强大,可安全吸收±30kV(接触放电,IEC 61000-4-2)时反复性ESD震击,而性能无任何降低。 Additionally, each diode can safely dissipate 80A of 8/20mssurge current (IEC61000-4-5, 2nd edition) with very low clamping voltages.
