The SMF5.0A responds to overvoltage transients in less than 1 nanosecond (typically 0.5ns to 0.8ns). This sub-nanosecond response provides instantaneous protection against ESD events per IEC 61000-4-2 (which have rise times as fast as 0.7ns to 1ns) and electrical fast transients (EFT) per IEC 61000-4-4 (5ns rise time). This speed ensures that sensitive CMOS ICs are protected from even the fastest transient events.
