General Purpose ESD Protection - SM24CANA
SM24CANA Series 200W TVS Diode Array
RoHS
Pb GREEN
Description
The SM24CANA TVS Diode Array is designed to protect
automotive Controller Area Network (CAN) lines from
damage due to electrostatic discharge (ESD), electrical fast
transient (EFT), and other overvoltage transients.
The SM24CANA Series can absorb repetitive ESD strikes
above the maximum level specified in the IEC61000-4-2
international standard without performance degradation
and safely dissipate 3A of 8/20s surge current (IEC61000-45) with very low clamping voltages.
