General Purpose ESD Protection - SM24CANA
SM24CANA Series 200W TVS Diode Array
Description
RoHS
Pb
GREEN
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 IEC 61000-4-2
international standard without performance degradation
and safely dissipate 3A of 8/20s surge current (IEC 61000-
4-5, 2
nd
Edition) with very low clamping voltages.
